Any other use of the inverter shall be considered inappropriate. The reading of the instructions included in the present manual and their compliance, particularly those ones referred to the safety, are considered a part of the appropriate use. Besides, the achievement of periodic inspections is also a part of the appropriate use. The inverter technician and not the manufacturer will be responsible for the personal and/or material damages resulting from an inappropriate use. 2.3. Product safety The product shall meet the quality and performance standards in effect at the time of delivery. The delivered product is mainly secure and reliable. The inverter and its additional or complementary elements must be used in fault-free conditions and they must be installed and used according to the use instructions. A use that exceeds the limits set out in Chapter 15 can lead to deterioration of the inverter. 2.4. Requirements for staff The persons in charge of planning, installation, adjustment and maintenance of the inverters must have the required qualification, aptitudes and training to carry out the job. Based on their knowledge and experience, they must recognize the potential risks of such a job. They must be aware of the safety regulations and guidelines for the prevention of accidents at the European, national and regional levels. Only staff trained for this purpose is allowed to operate and the apprentices will only do it under supervision. 2.5. Commissioning WARNING During the equipment commissioning, unexpected situations of risk may happen, due to a defective installation, faulty components, a bad adjustment or wrong electrical connections. During the adjustment, we must ensure the following points: • • • •

No persons or objects are in the danger area. The EMERGENCY STOP devices shall work properly. The overspeed governor (and all the other mechanical brakes) shall be activated. Compliance with applicable regulations and standards during the adjustment and commissioning.

2.6. Working on the inverter. Dangers due to residual voltage Before starting to work on inverters which have already been installed or in installation process, ensure that they are disconnected and cut off from the mains voltage. Also, take all the required measures to make impossible any inadvertent reconnection. There is a mortal danger of electrocution, even after the inverter has been disconnected, as its capacitors include electrical components containing energy that might have been charged due to a malfunction. When you want to manipulate the inverter, you must disconnect the power supply (R, S, T) and WAIT UNTIL THE LED DANGER HIGH VOLTAGE IS COMPLETELY OFF. Otherwise, there is a risk of electrical shock that can cause death. 2.7. Modifications/actions on the inverter For safety reasons, it is forbidden to perform on own behalf interventions and modifications on the equipment. All the modifications must be expressly approved by the manufacturer. Only materials/accessories supplied/recommended by MP must be used. These materials/accessories have been officially approved for use on the inverter. Otherwise, we cannot guarantee that they meet the relevant charge and safety standards. The spare parts and the special equipment that are not supplied/recommended by MP are not allowed for use on the device.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 3. GENERAL OVERVIEW OF THE 3VFMAC-DSP 6P 3.1. Application field The range of 3VFMAC-DSP frequency inverters is specifically designed for lift installations. It includes functions and configuration parameters that bring unique features to the frequency inverter applied to lifts with asynchronous and synchronous drive machines. 3.2. Functional description 3.2.1. General features With two access levels to parameters, the MP’s inverter handling is quick and easy. The parameter banks include functions like: S-curves, stop ramps, speed and current control, electronic motor protection, timers, external brake control, output frequency up to 65 Hz, regulation of the output voltage and monitoring the output phases. It allows real-time viewing of the most important electrical magnitudes. 3VFMAC-DSP 6P can operate in conventional open-loop control (voltage-frequency) and in closed-loop control. In the latter case, the inverter is able to supply up to 200% of rated torque at rotation speed 0 in a motor with the same power of the frequency inverter. FEATURES












Control of asynchronous and synchronous motors. Operating on battery power for emergency rescue. It detects the favourable direction of the load and carries out the lift motion at low speed using 5 batteries of 12 volts which are connected on the bus of continuous voltage. Emergency rescue without batteries for synchronous motors and with 4 batteries for asynchronous motors. Due to compatibility reasons, it also incorporates the rescue with 5 batteries, both for asynchronous and synchronous motors. It complies with standard EN-81 + A3 amendment, related to uncontrolled movements of the lift when the car is at landing level, with open doors, both with synchronous (from version 613) and asynchronous (from version 911A) motors. Static autotuning. Machine modeling by direct parameterisation of the electric constants of the motor (closed-loop control, synchronous motor). Self-adjustment of the sinusoidal encoder signals. Table of motors' characteristic values such as no load current, number of poles and machine constants. Current limiter of output to motor (synchronous motor). Configurability of the motion direction. Available communication interfaces RS-485, ENDAT, SSI, Serial TTL and CAN-BUS allowing the monitoring and remote control. “User-friendly” modular programming interface via computer or “on-board” keyboard.

COMFORT IMPROVEMENTS










1

Removal of the roll-back effect at starting. With asynchronous motors, it is achieved by using the VK2P weighing system; with synchronous motors, it incorporates the function of position control at starting and stopping. No electrical noise from the motor due to switching frequencies of up to 20 KHz in asynchronous motors and up to 14 KHz in synchronous, which allows its installation in machine room less lifts. Extra travel quality due to the automatic minimum jerk adjustment when starting and stopping, which removes the disgusting sensation caused by the acceleration at the starting and stopping moments. Characterisation of short ramps with two parameters: increase of target speed and hold speed timer. The converter uses these two data to automatically adjust the curve, with the same aim of comfort and the travel time at slow speed is reduced. Second order current filter removing the resonance frequencies generated by synchronous motors. Second order current advanced filter, with parameterisable cut off frequency, removing the resonance frequencies generated by synchronous motors. Direct access through absolute positioning, which allows the approach section to be removed, eliminating unnecessary waiting time for users 1. Progressive starting. For lifts with a backpack frame, there is an initial jerk due to the frame interlock on the guide rails. This feature makes possible to define a time interval during which a constant acceleration is applied, thereby removing the initial jolt felt in the car. It adds specific features for lifts, particularly affecting the comfort (5 S-curves) and the levelling.

There are two banks of speed and acceleration which will be activated by activating inputs provided for that purpose. 3.2.3. Operating modes The 3VFMAC-DSP 6P has two operating modes: RUN Mode and PROGRAMMING or SETUP Mode, as shown on the following diagram:

NO energy output STOP: Idle state waiting for a run command through XC10/XC2 inputs. Working mode Two possible states

Energy output RUN: The inverter is making the elevator move

Operating modes

Machine idle

Machine working

Setup Mode FIGURE 3.1 As shown, in RUN mode, two possible states are set out: Stop, where the inverter does not give energy and the machine remains idle and ready for running and Run, the inverter gives energy and the machine is working. In RUN mode, both stop and run states, no parameter can be modified. In this state, magnitudes such as speed, voltage, current, etc. can be real-time monitored. In PROGRAMMING or SETUP mode, the values of the parameters can be edited and adjusted. As we shall see later on, we can know at any moment whether the inverter is in RUN (Stopped or Running) or in PROGRAMMING mode because it is provided with both a console and a led to inform about its present state. 3.2.4. Parameterisation and monitoring The parameters are gathered in significant sheets or groups: Bank 1 of speed (TR1), Bank 2 of speed (TR2), Encoder (ENC), etc. The feature associated to the group or sheet is characterised into each sheet. 3VFMAC-DSP 6P offers a comfortable, easy and very operative technique of parameterisation (equipment configuration). In addition, the real-time viewing of the most outstanding electrical magnitudes is available: current consumption by motor, speed, target speed, voltage of capacitors, etc.

The inverter is provided with three voltage-free output signals which are controlled by the 2 relays and one triac located as shown in the previous picture. These are: - KRL1 This relay can be used for 3 different functions, depending on the motor type and whether the installation includes or not the EN81 + A3 amendment: overspeed governor interlocking, inverter state monitoring and speed limit relay, as shown in following diagram:

(1) Overspeed governor Interlocking/Release. This function is available for asynchronous inverters including A3 amendment activation. The output logic of this signal is the following one: Open relay (led SP off): Overspeed governor interlocking Closed relay (led SP off): Overspeed governor release (2) Inverter state monitoring. This function is available for synchronous inverters with A3 amendment feature activated. Through this signal, the inverter informs the control board about its state: Open relay (led SP off): Inverter offline Closed relay (led SP off): Inverter online/ready

(3) Limit speed relay. It switches when the value set in parameter TR0.01 is exceeded. In open-loop control, it switches when the output electric frequency exceeds it. In closed-loop control, it switches when the actual rotation speed of the motor exceeds it. The activation logic can be determined in the parameter TR0.02.

- KRL2: TRIAC FOR CONTROL OF CONTACTORS It controls, in series with the controller safety chain, the activation and deactivation of contactors, in coordination with the brake control (KRL3). - KRL3: RELAY FOR BRAKE CONTROL It controls, in series with the contactors, the opening and closing of the drive machine brake, in coordination with the control of contactors (KRL2).

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

6. ADDITIONAL ELEMENTS 6.1. Encoder We have to distinguish between asynchronous and synchronous machines:

- In asynchronous machines: the encoder use is optional, although it is highly recommended as it significantly improves the lift performance in regard with energy efficiency, control and comfort. Two encoder types can be installed: • Industrial Encoder. TTL. 5 Volts. • Magnet Encoder or low cost.

- In synchronous machines: the encoder use is mandatory, as this type of machines can only be controlled in closed-loop mode. For this kind of machines, the used encoder includes both the Endat01 absolute encoder technology and the incremental sinusoidal 1Vpp technology. The encoder use allows the flux vector control by 3VFMAC-DSP 6P with feedback of the speed reading (closedloop). This brings the following advantages: 1. Significant improvement in levelling. During the approach speed, the flux vector control guarantees that the motor always rotates at the same speed, independently of the existing load in the car. Furthermore, parameter RSN.05 (which is only operative in flux vector control) allows adjusting the levelling with absolute accuracy. As a final result, independently of the existing load in the car, the levelling point is always the same. 2. Overtorque. The main virtue of the flux vector control is to allow reaching the maximum possible motor torque over the entire frequency range. Thereby, in the event of overloads in car, the lift behaviour is much more reliable. 3. Electricity consumption reduction. The reduction in energy involved by the use of frequency inverter over other solutions (2-speeds, voltage inverter...) is well known. But, when operating with flux vector control the consumption is further more reduced compared to the conventional open-loop solution, because the equipment reduces very significantly the consumed current whenever the required torque is almost naught (for instance: half-loaded car). This also provides greater durability to the equipment. 4. Operating global reliability. The closed-loop control tends to make the motor rotate very close to theoretical curve of speed, due to the optimum dynamic response of the set. These advantages apply to both synchronous and asynchronous machines.

FIGURE 6.1

To ensure the proper motion of the car and to make it properly coincide with the encoder reading, you must perform the following actions in the specified order: 1. Set the equipment to make it operate in open-loop mode (CNF.00=0). Make the car move and confirm it goes upwards when the ascent order is given (and vice versa). If the car motion is in the opposite direction to the commanded one, exchange 2 phases in the power connectors of output to the motor inside the controller (terminals U, V, W). Confirm that now the motion coincides with the given order. 2. After that, connect the encoder. Be especially careful, because the encoder can be deteriorated if the connections are not properly done. Confirm that the number of motor poles (DRI.03) and the number of encoder pulses (ENC.00) have been set to the proper values. 3. The following checks must be done in stop, in upwards and downwards. The encoder will be OK if and only if the three conditions related here below are complied with:

V0.01 – 04/2013

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

• Stopped. The "Encod" value will be displayed. We will touch the encoder connector; we will • •

smoothly pull the cables. The value should remain at 0. If not, the encoder connection shall be checked. Upwards. The "UEL" viewing must be a positive value and very close to "FrEC", the "E5" viewing must also be positive and close to "FrEC" and the value of "Encod" counter shall be decreasing. Downwards. The "UEL" viewing must be a negative value and its absolute value very close to "FrEC", the "E5" viewing must also be negative and its absolute value close to "FrEC" and the value of "Encod" counter shall be increasing.

If all the specified conditions are not met in any of the described situations, there is a problem with the encoder. The most common problems related to the encoder are: a) While the lift is moving, upwards or downwards, if the “Encod” viewing value remains at zero, it means there is a connection error in the encoder (power supply, a non-connected channel). Check once more the connections. b) In the "UEL" viewing, if a rotation speed with opposite sign to the electric frequency of “E5” output appears, it means that the two channels of the pulse train are connected in reverse order. To correct the order, the channels must be exchanged one another; i.e., exchange the cable C1 + for the C2 + and the C1 – for the C2 -. c) If “UEL” and “E5” values have the same sign, but they differ significantly, check parameters DRI.03 (number of poles) and ENC.00 (number of encoder pulses). After the above mentioned points have been checked, repeat all the operations included in this section from the beginning. 4. Introduce the value of motor no-load current in parameter INT.00. It is more or less equal to the current consumed by the motor when operating in open-loop mode (CNF.00=0), at rated speed, when the car is empty and moving upwards. Read this current on the equipment display, introduce it on INT.00. Set the inverter in closed-loop mode (CNF.00=1). First, in inspection mode or rescue mode and, after, in normal mode, make the car travel several times. As a precautionary measure, lower the high speed (TR1.00), just in case there is any kind of problem. At this moment, if there are vibrations or if error 05 or error 11 appears, check the proper connection to ground of the encoder shield, at the connection of the encoder to the controller, as shown in below picture:

PICTURE 6.1 Regarding to inverter configuration, to ensure the inverter proper functioning, we must: 1. Check that the machine number of poles is correct (parameter DRI.03). 2. Set the value of parameter ENC.00 (encoder number of pulses) according to the number of pulses per turn indicated by the encoder manufacturer.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

6.1.2. Low cost encoder (asynchronous motors only) 3VFMAC-DSP 6P frequency inverter is provided with a connector (XC3) to allow using a low cost encoder. It is recommended to use this encoder type whenever the coupling of an industrial encoder to the machine is not possible and whenever the functioning in open-loop mode is not able to meet all the wanted expectations. Its use shall be limited to situations when the adaptation of a digital encoder to the machine is absolutely impossible. Due to its low resolution, the obtained comfort rate will always be well below the comfort degree provided by an industrial encoder. The connector C3 includes the following connections: 20: positive terminal of encoder power supply (+10 Vdc). 21: negative terminal of encoder power supply (0 Vdc). 22: Reading of pulses, channel 1. The encoder maximum consumption will be 40 mA. The encoder must be provided with open-collector outputs. The low cost encoder consists of magnets (8, 10 or 12) located on the machine handwheel (or equivalent part), equidistantly placed and with alternating polarities. A sensor (supplied with the equipment) will be placed in such a way its active front face (marked with a white point) is fully facing the magnets. The maximum distance between the white point and the magnets will be 2 mm.

FIGURE 6.2

Together with the sensor and magnets, a string and some metal profiles are supplied. The string enables placing the magnets in a quick and easy way. Place (usually) 12 magnets: 1. Embrace the handwheel with the string and make a knot so that the string keeps the handwheel perimeter size. 2. Take out the string, stretch it and mark the end. Now the handwheel is divided into 2 parts. Fold the marked end upon the knot; mark the 2 new ends of string and now the handwheel is divided into 4 parts. 3. Place back the string embracing the handwheel. Marks on the string indicate the first 4 division points of the handwheel. 4. By using the string, subdivide each quarter of the handwheel until all the points are achieved. 5. Fix the magnets with high-tack glue (Loctite or similar). Ensure their perfect fixing.

FIGURE 6.3

VERY IMPORTANT: the positioning of the magnets is very important. They must be perfectly equidistant.

VERY IMPORTANT: The polarity of the magnets must be alternate. In order to confirm the correct positioning, connect the equipment to the encoder (paying attention to the numbering) and turn on the power on the frequency converter only (not on the control board). By hand, make the motor move. Each time a magnet faces the sensor, the LED must change its state. Regarding to the converter configuration, in order to get a proper operation, we must: 1. Check that the machine number of poles is correct (parameter DRI.03). 2. Set the value of parameter ENC.00 (encoder number of pulses) like the number of placed magnets divided by two, as each couple of magnets generates one pulse. Therefore, if the numbers of permitted magnets are 8, 10 and 12, the values of ENC.00 associated to each of them are 4, 5 and 6, respectively. 6.1.3. Absolute/sinusoidal encoder (synchronous motors only) 3VFMAC-DSP 6P frequency converter is provided with four connectors (XC6, XC8, XC7 and XC5) to allow using an absolute/sinusoidal encoder. It is IMPERATIVE and MANDATORY to use it for the control of synchronous machines. It will be placed in the motor and it will enable the equipment to know in real time the rotation speed and the rotor exact position, which are necessary conditions for the control of this type of machines. Even though it is a single physical device, actually, this encoder type consists of two different encoders: the absolute encoder and the sinusoidal encoder. It must be supplied together with the machine, and its features are: - Power supply: 5 Vdc. - Sinusoidal encoder: two differential sinusoidal channels, 1Vpp geometrically displaced in 90º. 2048 cycles per turn recommended, and the valid values are 512, 1024, 2048 and 4096. - Absolute encoder: Protocol Endat01® (proprietary protocol Heidenhain). It consists of two differential channels of data and clock, with 8192 positions for a complete turn.

The sinusoidal/absolute encoder connection to 3VFMAC-DSP 6P is made through an adaptor cable supplied by MP.

PICTURE 6.2 As shown in the picture, the cable is provided with a female connector DB15 at one end which will be connected to the male connector DB15 of the machine encoder. The other end is provided with 2 Wago seven-pole connectors (XC6 and XC8), 2 two-pole Wago connectors (XC5 and XC7) and 1 three-pole Wago connector (power supply, with two terminals +,- only). This adaptor cable will be integrated in controllers supplied by MP. In the first controllers for controlling synchronous machines, the encoder shield was connected to terminal 1 of the connector XC6. Now, the shield connection to this terminal has been removed. Approximately 1 cm of the adaptor shield is bare to be fixed with screw/washer to bottom plate of the cabinet. To ensure the proper motion of the car, we must check the absolute encoder and sinusoidal encoder; it is mandatory to make following operations in the specified order: 1. Confirm the values of following parameters: ENC.00: We must set ENC.00 to the number of pulses per turn of the encoder coupled to the motor. It is very important to be sure about this value. A mistaken value at this parameter may cause an overspeed and/or an erratic behaviour. ENC.01: 21

After making all these checks, press the inverter red button (PR). If error 05 still persists, contact MP Lifts staff. 3. Set the control board in inspection mode or in MES mode. 4. Move the lift upwards or downwards. If err51 appears when starting, we must make following checks: a) Check the proper connection of connectors XC5 and XC7 to the inverter. b) Check that the Wago connectors do not bite the plastic. c) Check the proper connection of the adaptor cable to the terminal DB15 of the encoder cable. d) Check one by one the electrical continuity of the adapter cable wires, according to previous table (TABLE 6.1.2). e) Check that the encoder supports the Endat protocol, as shown in here below picture.

PICTURE 6.3

If error 05 still persists, contact MP Lifts staff. 5. At this point, we must check the motion direction. Let us remind that the control board is in Inspection mode or in MES mode. After checking that point, press the upwards (or downwards) button. If the lift moves downwards (or upwards), i.e., it travels in the opposite direction of the commanded one, we must modify parameter CNF.05: If CNF.05 = 1, set CNF.05 = 0 If CNF.05 = 0, set CNF.05 = 1 Try again to press the upwards (or downwards) button and verify the proper motion direction. VERY IMPORTANT: WITH SYNCRHONOUS MACHINES, TO MODIFY THE MOTION DIRECTION, NEVER, UNDER NO CIRCUMSTANCES, CHANGE THE ORDER OF THE OUPUT PHASES TO THE MOTOR, as done with asynchronous machines.

6.2. Weighing control: VK2P (asynchronous only) 6.2.1. Description This feature is available for asynchronous motors only. This performance is an optional feature. This system enables 3VFMAC-DSP 6P, by incorporating a weighing reader (VK2P), to adjust the required motor torque to carry out a service independently from the load in car. The main aim of using the VK2P is to avoid the roll-back effect when starting and it is particularly suitable for lowinertia machines. The user shall indicate the car maximum load Q (parameter PSO.00), as well as the maximum torque that the system will apply in order to correct the load in car (parameter PSO.01). This feature will be operative only if the equipment is configured in close-loop mode with industrial encoder. 6.2.2. Requirements 1. Weighing reader VK2P with bedframe/car (model TCE) load cells and a proper calibration. 2. Communication between both systems. The communication between 3VFMAC-DSP 6P and VK2P is of RS485 type and it is carried out between terminals T1 and T2 of connector XC5 and terminals T1 and T2 of VK2P, respectively. 3. Operation mode 3VFMAC-DSP 6P CLOSED-LOOP with industrial encoder (CNF.00 = 1, ENC.00 ≥ 500 and ENC.00 ≤ 5000). 6.2.3. Parameterisation For the activation/deactivation of this feature, there is no parameter. As a matter of fact, whenever 3VFMAC-DSP 6P is connected to a VK2P, this feature is activated. But in the group PSO, there are parameters dedicated to the weighing control configuration: PSO.00: Maximum load in car in kilograms. Range from 200 up to 3000. Default value depending on model: 10 HP: 450 Kg; 15 HP: 630 Kg; 20 HP: 900 Kg. PSO.01: Torque percentage in regard with the rated torque to be applied for the maximum load. Range from 0 up to 50. Default value: 0. As mentioned in previous section “Requirements”, this feature will be operative if 3VFMAC-DSP 6P is configured in closed-loop mode with industrial encoder. Therefore, CNF.00: Maximum load in car in kilograms. Range from 200 up to 3000. ENC.00: Number of pulses per encoder turn. Range: 500…5000. Default value: 2000. 6.2.4. Viewing There is only one viewing for this weighing control feature monitoring (refer to chapter 7): Weight. The possible values of this viewing are:

Value in kilograms registered by VK2P, positive or negative, depending on the car situation and its load. Or, “PSoEr”, if there is a connection problem or if VK2P is not connected to 3VFMAC-DSP 6P.

General 3VFMAC-DSP 6P enables the viewing in real time of the most relevant electric, dynamic and control magnitudes: current consumption of the motor, speed, target speed, voltage of capacitors, encoder reading of pulses, etc. The monitoring and viewing of these magnitudes are available in RUN mode only, both in idle state or running. The viewing main aim of these magnitudes is to enable checking the proper functioning of the encoder and installation as well. Therefore, these viewings can and should be used as a tool for detection, debugging and solving problems that may affect the inverter. 7.2. Console handling Let us remind that the console or user interface of 3VFMAC-DSP 6P consists of five 7 segment- displays and four buttons which are set out as shown in the following figure:

FIGURE 7.1 The actions associated to each button in monitoring mode are shown in the following table: BUTTON

ACTION If the inverter is in RUN mode and in idle state (without providing energy), change it to SETUP mode. When a service is running, pressing this button does not produce any effect.

It changes to the next viewing. For two seconds it will display the value legend and, after, it will display the magnitude value. If the active magnitude is the last one, it will change to the first one.

It changes to the previous viewing. For two seconds it will display the value legend and, after, it will display the magnitude value. If the active magnitude is the first one, it will change to the last one.

It displays the magnitude legend that is being visualised for two seconds. After, it displays again the value.

As noteworthy and common aspects for synchronous and asynchronous viewings, let us say that: a) The main viewing is always the first. In addition, if no button of the console is touched for three minutes 3VFMAC-DSP 6P will set the main viewing as the active one. b) At any moment, we can know the displayed magnitude by pressing the button
, except when displaying the main viewing and the error viewing. c) We can move forwards and backwards along the displayed magnitudes with the buttons  and ⊳, respectively. Furthermore, when we are on the first viewing, the previous one is the last one and when we are on the last viewing, the next one is the first one.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 8. PARAMETERS 8.1. General The inverter parameters have been structured in pages or groups. Each page can contain up to 16 parameters and is identified with an acronym of three letters. Each parameter is identified by the group acronym to which it belongs and a 2-digit number, with a value from 0 to 15 that determines its position or order into the page. For instance: the acronym “CNF” has been assigned to the page “General configuration”. This page first parameter is “Type of Control” and the second one, “Type of inverter”. The way of appointing each parameter will be CNF.00 and CNF.01 respectively. Whenever we enter the programming mode, we must give an access code. The access level of each parameter is determined by this key and, in some case, by the value of other parameters. There are three access codes: Normal, Advanced and Default. On the other hand, there are three access levels per each parameter: Reading/Writing, Reading only and Not visible. In the tables of this chapter, each parameter access level corresponding to each access code will be determined. Example 1: To modify any VEL group parameter, the access to programming mode with advanced key is required. Otherwise, it will appear as “Reading only”. Example 2: The VEL group parameters will be visible only if the parameter CNF.00 = 1, i.e., if the inverter has been configured in closed-loop mode. The parameters can be adjusted from the inverter console itself or by using the PC program MPConfig (refer to chapter 13, section 13.1).

8.2. Console handling in programming mode Let us remind that the console or user interface of 3VFMAC-DSP 6P consists of five 7 segment- displays and four buttons which are set out as shown in the following figure:

The action or actions assigned to each button depend on the context or level in which we are at each moment. The way to know in which level or context we are at each moment is the information shown on the displays.

TABLE 8.2 (1) The parameter DRI.08 (code of motor model) is a fictitious parameter. When entering the motor code, the parameters of no load current (INT.00), number of poles (DRI.03) and machine constants (DRI.01, DRI.02) are set. However, their values do not remain. For instance: We edit the parameter DRI.08 and enter the value 204. In so doing, the console display will l show “Po” blinking, i.e. the entered value is right. The parameters DRI.01, DRI.02, DRI.03 and INT.00 have been set to 88.5, 88.5, 4 and 14.2, respectively. If we edit once again the value of DRI.08, 0 will appear once more.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 9. Control of the inverter This chapter describes in detail the inverter signals involved in its control. These signals can be divided into two large groups: Voltage-free inputs enable the inverter to be operated by any type of control board. The connection terminals are located in connector XC2 or XC10, depending on the type of control board. Furthermore, 3VFMAC-DSP 6P is equipped with a special additional input in connector XC3 for the rescue or emergency signal. Voltage-free outputs: The equipment includes 3 relays with outputs through voltage-free contacts. The connection terminals are located in connector XC4. The function and sequence of these relays cannot be modified by means of configuration. Within each group of control inputs and outputs, some are optional and some are compulsory. When we describe them, we will indicate for each one whether it is compulsory or optional. The signals marked with (*) must be imperatively incorporated. The remaining ones are optional.

PICTURE 9.1 (*)The three LEDs of voltage-free outputs are located at this place. In addition to these three LEDs, in the upper part, you can find the LED EM, associated to the activation signal input of the automatic rescue with batteries.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 9.1. Inputs If the control board operating the inverter is MicroBasic or a non-MP one, the used connection terminals will be those of connector XC2. If the control board operating the inverter is Via Serie, the used connection terminals will be those of connector XC10. Independently of the used connector (XC2 or XC10), the references of the connection terminals will be the same ones. The only input signal that is not located in connectors XC2/XC10 is the rescue or emergency signal (EM). Like for the other signals, it is a voltage-free signal, so that for DSP rescue with 5 batteries the terminals 20 and 23 of the connector XC3 can be used; but, in case of DSP rescue with 4 batteries (asynchronous) or DSP-UPS rescue without batteries (synchronous) the terminals 21 and 23 of the same XC3 connector shall be used. Let us remind that the state of the input signals can be monitored through the input LEDs, as shown in picture 9.1. Those LEDs are silk-screen printed with a number that coincides with the ones of the terminals of the input signals:

PICTURE 9.2 The monitoring LED of the rescue or emergency input signal (EM) is in a different bank of LEDs, close to the LEDs of the output signal activation; it is silk-screen printed with EM. 9.1.1. Emergency stop (contactors’ reading) Connector XC13, terminals 11 and 12. It is compulsory (*). This signal informs the frequency inverter that the contactors K1 and K2 are activated. It analyses the signal when activating the relay KRL2 (by activating the contactors). At the beginning of a service or during it, if the EMERGENCY STOP signal disappears, the inverter will immediately cut off the energy supply, it will deactivate the triac KRL2 of contactors, brake relay KRL3 and it will display the error 0E (uncontrolled opening of contactors). This situation shall occur when any safety contact of the installation opens during a service (for instance: default in door lock contact). When the error 0E appears, it is displayed for approximately 1 second and during this period the inverter is inhibited (it does not accept any command input signal). After that time, it starts running normally again. 9.1.2. Run Connector XC2/XC10, terminal 13. It is compulsory (*). This signal activation triggers the execution of a service, therefore causing the start-up sequence indicated in the diagram of starting and stopping. 9.1.3. Rated speed / Approach speed Connector XC2/XC10, terminal 14. It is compulsory (*). This signal informs the inverter about which has to be the motor turn frequency: Activated: RATED speed. Deactivated: APPROACH speed. By changing this signal, the frequency will gradually be modified (depending on the acceleration, deceleration times and the S-curves), until reaching the frequency/speed target. The rated speed is determined by the parameter TR1.00 value and the approach speed by the parameter TR1.01 value. If the input signal of the speed 2nd bank is activated (refer to next section), the rated speed will be determined by the parameter TR2.00 and the approach speed by the parameter TR2.01.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 9.1.4. 2nd Speed Bank Connector XC2/XC10, terminal 15. Optional. This signal activation enables using a second group of RATED AND APPROACH speeds: PARAMETERS RATED SPEED APPROACH SPEED TR1.00 TR1.01 TR2.00 TR2.01 TABLE 9.1

Terminal 15 DEACTIVATED ACTIVATED

If you do not need to use this function, keep the terminal nr 15 unconnected. 9.1.5. Inspection speed Connector XC2/XC10, terminal 16. Compulsory (*). Its activation selects the motor turn frequency in inspection mode. Connect to the terminal nr 16 a contact of the inspection switch or a contact of a relay activated by this switch. The contact must be normally closed, i.e., open when the inspection mode is activated. Therefore, this signal is interpreted by the inverter in the following way: Activated: Control board in normal operation, NOT in inspection operation. Deactivated: Control board in inspection operation.

The inspection speed is defined in the parameter TR0.00. In inspection mode it is recommended to deactivate the contactors from the control board without any delay (by opening the run contactors). This way, the lift will stop immediately as soon as you stop pressing the upward or downward command, allowing quicker and more precise maintenance works. In the installations supplied by MP, inspection operation is made this way. Therefore, whenever you stop pressing the upward or downward command (in inspection), the error 0E will appear, as the contactors are immediately deactivated from the control board. 9.1.6. 2nd Acceleration Bank Connector XC2/XC10, terminal 17. Optional. The acceleration and deceleration times define how long it takes to the frequency inverter spends to go from frequency/speed zero to frequency/rated speed (acceleration) and from frequency/rated speed to frequency/approach speed (deceleration). The 2º bank of ACCELERATION / DECELERATION signal enables using two different groups of parameters to carry out the acceleration and deceleration in the motor:

9.1.7. Run direction Connector XC2/XC10, terminal 18. Compulsory (*). It allows selecting the motor turn direction without needing to use an additional contactor to carry out the up and down movement of the lift. To adjust the run direction, it is recommended to operate in inspection or MES mode. Press the upward or downward button. On this point, we have to make the difference between asynchronous and synchronous motors:

ASYNCHRONOUS When commissioning the lift, if you observe that the movement direction is reversed, exchange 2 phases of the power output to motor. Do not modify the UP / DOWN signal wiring, neither the phases of the frequency inverter power.

SYNCHRONOUS

IMPORTANTE: With synchronous motors, when commissioning the lift, if you observe that the movement direction is reversed, NEVER exchange the output phases to motor.

The exchange of the output phases to motor will cause an erratic functioning, a blocking or a runaway of the machine. To set the proper run direction: 1) Set the control board in inspection or MES mode. 2) Press the up (or down) button. -

If it runs down (or up), i.e., if the motion direction is the reverse of the commanded one, modify the parameter CNF.05: If CNF.05 = 1, set CNF.05 = 0 If CNF.05 = 0, set CNF.05 = 1

- Try again to press the up (or down) button. 9.1.8 Error reset/reading of brake microswitches/reading of overspeed governor interlocking coil state (EN81+A3 amendment) Connector XC2, terminal 19. Optional. This terminal is not available in the connector XC10. In asynchronous motors, this terminal function is configured through the parameter A3A.00 as following:

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

In synchronous motors, this terminal function can be configured through the parameters A3A.00 and/or STC.08 as following:

READING OF BRAKE MICROSWITCHES N/CLOSED. FUNCTION EN81+AMENDEMENT A3 ACTIVATED WITH AUTOMATIC RESET. TABLE 9.4

From this table, we deduce that the value of STC.08 takes effect if and only if A3 amendment function is not activated, i.e., if A3A.00 = 0. If this function is activated (A3A.00=1 or 2), the reading of brake microswitches will be activated in normally closed mode, INDEPENDENTLY of the recorded value in STC.08. Automatic reset means that the occurrence of an error associated to A3 amendment will NEVER leave the inverter in permanent out of service. On the contrary, the manual reset means that the occurrence of any error associated to A3 amendment will leave the inverter in permanent out of service, so that, to reactivate it, the presence of maintenance staff is required. The meaning of both terms applies to the EN-81+ A3 amendment function and it is the same for both asynchronous and synchronous motors. 9.1.8.1. Error Reset Function The frequency inverter can detect different error situations that cause the lift stop. When an error occurs, the inverter requires a RESET to be done to go on operating after. There are four possible ways to apply a RESET: a) By turning off and on again the equipment. b) By using the AUTORESET function (CNF.02, the digit on right). Automatically, the equipment carries out a maximum number of RESET during a period (3 minutes). c) By entering in PROGRAMMING mode and coming back to RUN mode. d) By applying the ERROR RESET. The activation of the ERROR RESET signal takes no effect when the inverter is giving energy. When the equipment does not supply energy and the terminal nr 19 is activated: a) The display shows the text RESET blinking as long as the signal applies. b) If there was an error, it will be reset. c) The moment the signal is not applied any more, the equipment will be ready to carry out a new service. If there was an error, it will be reset and the moment the signal is not applied any more, the equipment will be ready to carry out a new service. As long as the signal is activated, the inverter will not carry out any service, even if the RUN output remains activated. The activation of the ERROR RESET signal does not avoid that the AUTORESET function records one unit more (on the counter of maximum number of RESET during a period of 3 minutes) when an error appears.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter Do not make an usual use of the ERROR external RESET signal. The AUTORESET function ensures that sporadic errors do not cause the lift permanent stop; however, in case of repetitive occurrence of errors (that could lead the lift to critical situations), the equipment stops operating. 9.1.8.2. Function reading of brake microswitches (Synchronous machines only) The synchronous machines are equipped with two brake discs. Each of them includes a microswitch to allow its state monitoring. There are two possibilities: Normally open: with deactivated brake (mechanically closed), open. Normally closed: with deactivated brake (mechanically closed), closed. As there is only one input, both brake microswitches must be wired together, in parallel or in series. The MP machines are supplied with normally closed in series microswitches. As said before, this signal is optional, even if its use is highly recommended. IMPORTANT: If the parameter STC.08 is set to 0 and the parameter A3A.00 is set to 0 (ERROR RESET function), we must disconnect the terminal 19 of the connector XC2. Otherwise, even if receiving the RUN signal (terminal 13), the inverter will not start.

9.1.8.3. Reading of overspeed governor interlocking coil state (EN81 + A3) (Asynchronous machines only) To implement A3 amendment function on installations with asynchronous machines (geared), an overspeed governor interlocking coil is used. When this device is inactivated, the overspeed governor is interlocked. When it is activated, the overspeed governor is released. This device is fully commanded by the inverter: the activation is carried out through the relay KRL1 (XC4, 32-33) and its state reading is carried out through the microswitch included into the interlocking device and through the input XC2/19: - Activated input (led 19 on): interlocked overspeed governor. - Deactivated input (led 19 off): released overspeed governor. Let us suppose that the inverter is included in a controller provided with A3 amendment function. If the parameter A3A.00 is set to 0, i.e., if A3 amendment function is disabled in the inverter, the input 19 function is ERROR RESET. Therefore, the inverter will display the text “rESEt” blinking and even if receiving the RUN signal (terminal 13), the inverter will not start running. 9.1.9. Rescue signal (EM) Connector XC3, terminals 20 and 23 or 21 and 23. Optional. This voltage-free input proceeding from the control board is a special input. This signal activation causes that, after being properly configured, the inverter enters a special operating mode: automatic rescue mode. There are 3 automatic rescue modes, detailed in the following table: AUTOMATIC RESCUE MODE

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

At this moment, the DSP Rescue 4 batteries mode is the standard rescue mode for asynchronous machines and the UPS Rescue (without batteries) mode is the rescue mode for synchronous machines. The reason why the DSP Rescue 5 batteries mode (synchronous and asynchronous) remains is the compatibility with existing installations where it is incorporated. For the full description of the rescue or emergency special function, refer to Chapter 9, section 9.5. However, it is important to highlight two things regarding the input signals: 1. During all the rescue process, the rescue signal will remain activated. If the input of the rescue signal is deactivated for more than 3 seconds during the process, the inverter will interrupt the rescue operation. If the signal is reactivated, it will start from the beginning. 2. In rescue mode, the only voltage-free input in the main board input connector (XC2/XC10) that 3VFMACDSP 6P will take into consideration will be the RUN signal (#13), as its activation will determine the beginning of the rescue process. The target speed and the direction will be determined by the inverter itself according to the rescue mode (DSP 5 batteries, DSP 4 batteries or DSP-UPS), the load and the parameters associated to the rescue module (group RES). 9.2. Voltage-free outputs The equipment is equipped with 2 relays and one triac that offer outputs through voltage-free contacts. The connection terminals are located in the connector XC4. El state of the output signals can be monitored at the output LEDs, located as shown in the Picture 9.1. A zoom on the area of the output LEDs will let us see what is shown on the following figure: OUTPUT LEDS

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

Let us suppose that the inverter is included in a controller provided with A3 Amendment function. If the parameter A3A.00 is set to 0, i.e., if A3 Amendment function is disabled in the inverter, the input 19 function is ERROR RESET. Therefore, the inverter will display the text “rESEt” blinking and even if receiving the RUN signal (terminal 13), the inverter will not start running. 9.2.1.1. Relay of speed limit It enables informing the controller the electrical frequency output (open-loop control) or the actual speed of the machine (closed-loop mode) is higher than the defined limit at the parameter TR0.01. A switching of the relay of speed limit can be done when the value set in parameter TR0.01 has been exceeded by: a) b)

The output frequency, if the equipment operates in open-loop control The actual speed of the motor, if the equipment operates in closed-loop control

If the parameter is set to zero, the switching of relay of logic of contacts will never occur. Depending on the set out logic in the parameter TR0.02, the relay will be operated in the following way: a) Positive logic (TR0.02 = 1) Lower value than TR0.01: open contact Higher value than TR0.01: closed contact b) Negative logic (TR0.02 = 0) Lower value than TR0.01: closed contact Higher value than TR0.01: open contact Use this relay when the lift is provided with approach to floor with doors pre-opening. The inverter will inform on the moment that the car speed is lower than a determined value (required by EN-81). Example: In a lift of 1.0 m/s in which we want to start the doors pre-opening when the speed is lower than 0.15 m/s, if 1 m/s corresponds to 50.00 Hz, at 0.15 m/s, the output frequency would correspond to (50.00*0.15) / 1.0 = 7.50 Hz. Therefore, the parameter TR0.03 value should be set to 7.50 Hz. 9.2.1.2. Overspeed governor Interlocking/Release This function is available for those asynchronous inverters provided with A3 Amendment function activated. With asynchronous machines (geared), the interlocking coil of the overspeed governor is used. When this device is inactivated, the overspeed governor is interlocked. When it is activated, the overspeed governor is released. This device is fully commanded by the inverter: the activation is carried out through the relay KRL1 and its state reading is carried out through the microswitch included into the interlocking device and through the input XC2/19. To check whether the inverter has activated or not KRL1, we will visualize the SP LED state (refer to table 9.6):

• On: Overspeed governor released. • Off: Overspeed governor interlocked. Therefore, when the lift is stopped, KRL1 is deactivated (SP LED off). When the lift is moving, KRL1 shall be activated (SP LED on). For further information, refer to chapter 5 about electrical installation. 9.2.1.3. Inverter state monitoring This function is available for those asynchronous inverters provided with A3 Amendment function activated. This voltage-free output is directly connected to a main board input: in Via Serie, the input KP2; in MicroBasic, the input 4. Thus, the control board is informed at any time about the inverter state:

•

KRL1 will be activated, SP LED on, if the inverter is ready to carry out a service.

•

KRL1 will be deactivated, SP LED off, if the inverter is not ready to carry out a service. The inverter will be “offline” if it is in permanent out of service due to an error, or it is in programming mode or it is off.

For further information, refer to chapter 5 about electrical installation.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 9.2.2. Contactors’ control triac (KRL2) (*) Connector XC4, terminals 34 and 35. It is compulsory. The CONTACTORS’ CONTROL enables the inverter to carry out the optimum (in comfort terms) starting and stopping sequence, by acting on the contactors. The activation of the contactors is commanded by three groups of contacts placed in series: a) Contacts of the safety chain. b) Control from the control board (the run contactors). c) Control from the frequency inverter through KRL2. Refer to the diagrams at chapter 5 to check the required wiring of the contactors’ control, in order to obtain a proper operation. 9.2.3. Relay of brake control (KRL3) (*) Connector XC4, terminals 36 and 37. It is compulsory. 3VFMAC-DSP inverter carries out the mechanical brake control of the drive machine through the relay KRL3. This output is used to activate an external relay or contactor of the brake. A brake relay contact (or brake external contactor) will be placed in series with contacts of the contactors K1 and K2. This brake control is the most usual, the most reliable and the cheapest. The relay KRL3 makes possible an easy brake control that provides great comfort: 1. The relay KRL3 will command an external relay KRFR (brake relay).

Diagram 9.2

Depending on the brake type and/or the machine type, the power supply, the brake actuator device and the advisability or not of using a filter (A*) and/or varistors can vary. For further information, refer to chapter 5 about electrical installation. 9.3. Sequence This section describes the logical sequence, in normal mode, for the activation of the input and output signals. For the description of the DSP rescue function, refer to chapter 9, section 9.5 as it is a special operation mode. The RUN signal (XC2/XC10-13) activation triggers the execution of a service, therefore causing the starting sequence shown in starting and stopping diagram 9.1. The RUN signal comes out from the control board and is responsible of its deactivation (causing the stopping sequence) as soon as the level floor is reached. The control board must wait until the inverter opens the contactors. This opening informs the control board that now the service can be achieved. The contactors’ control is carried out together from the control board and the inverter. The control board’s run contactors and the inverter KRL2 are in series. Therefore, to avoid the activation of the contactors, both output signals have to be activated in both the control board and the inverter. However, the activation of these signals has to be carried out according to sequence shown in the here below table: CONTACTORS’ CONTROL STARTING SEQUENCE 1º 2º 3º 4º

STOPPING SEQUENCE The floor level is reached. The RUN signal is deactivated The motor is electrically stopped. KRL2 is deactivated and the contactors are open.

Safety contacts closed The run contactors are activated. The RUN signal is activated. The frequency inverter activates KRL2 and closes the contactors The lift starts

The run contactors are deactivated. The service finishes

Where: Action achieved by the control board Action achieved by the inverter TABLE 9.8 If the starting and stopping sequences are not carried out like explained or if, during a service, the safety chain or the run contactors are eventually open, the error 0E will be generated and KRL2 (contactors) and KRL3 (brake) will be deactivated. The inverter will remain disabled for approximately 1 s., the error will be reset and, then, the equipment will be ready to operate again. El error 0E is “” (AUTO RESET type) 5; i.e., even if it appears many times, it will never cause the inverter permanent stop.

5

As we will see forward in chapter 10, there are two types of errors: “uncountable” (AUTO RESET type) and “countable” (NO AUTORESET). The digit on the right of parameter CNF.02 determines the maximum number of errors for three minutes. Whenever a “countable” error (NO AUTORESET) occurs, the counter increases the recording of errors. When the value of the digit on the right of parameter CNF.02 is reached, the inverter remains out of service. V0.01 – 04/2013

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter The brake control, unlike the contactors’ control, is exclusively carried out by the frequency inverter. During the starting sequence KRL3 is activated (the brake opens) just after the contactors have been activated (after activating KRL2). So as not to start the motor turn until the brake is full open, the target frequency/speed does not begin to increase (acceleration ramp) until the time defined in parameter STC.00 is elapsed after the KRL3 acting. During the stopping sequence, KRL3 is deactivated (therefore acting the mechanical brake) before deactivating the contactors. Before deactivating KRL3, the motor will be electrically blocked and it will wait as long as the time defined by the parameter STC.01 (brake delay before the stop). The detailed and full execution of a service by the inverter is set out in previous page, schema 9.3: starting and stopping, with all the involved inputs and outputs, as well as the associated parameters. The function of position control and also the parameter STC.09 apply to synchronous motors only. This parameter determines the current drop time after the brake closing. In this machine type, as there is no gear, if the current is abruptly interrupted, a snapping noise occurs, because of the little play of the brake.

The magnetizing time (3), indicated in the starting sequence, applies to asynchronous motors ONLY. This motor type, unlike synchronous motors, does not have permanent magnets. Therefore, the magnetic field must be created before the brake opening. All the other involved parameters are common to both motor types and they are those ones concerning the two speed banks (TR1, TR2), the starting and stopping (STC) and those concerning the adjustment of S-curves (RSN).

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 10. MANAGEMENT OF ERRORS 10.1. Error Reset The equipment can detect different error situations. To return to normal operation mode, RESET the error. Otherwise, the equipment will remain out of service. There are several possible ways to carry out an error RESET: a) By turning off and on again the equipment. b) By pressing the red button P/R in the console. c) By entering in SETUP mode and coming back to RUN mode. d) By the AUTORESET function. e) By running an external Reset. The RESET of an error is possible only when the originating cause disappeared. 10.1.1 Autoreset Function that automatically carries out a maximum number of RESETs in 3 minutes. During this period, if as many errors as the maximum number set out (figure entered in parameter CNF.02 right digit) appear, the equipment will remain out of service until an error RESET is carried out by any other mean. Every time the equipment is turned off and on, or we enter or exit the PROGRAM mode, the internal counter of number of errors within 3 minutes will switch to 0; i.e., as many errors as the maximum number set to parameter CNF.02’s right digit value will be allowed in the next 3 minutes. The AUTORESET function waits until the error cause disappears to generate (and count) the RESET. 10.1.2 External Reset of an Error (Terminal 19 connector XC2) To have this function activated, let us remind that A3 Amendment function is to be deactivated and, for synchronous motors, in addition to the function of reading of brake microswitches (refer to tables 9.3, 9.4). An error RESET can be carried out through a voltage-free external contact, in terminal nº 19 of the connector XC2. If this external RESET is applied together with the AUTORESET function, the AUTORESET internal counter will never be increased. If the AUTORESET function exceeds the maximum number of allowed errors, the external reset application will not restore the AUTORESET counter to zero. When an external reset is carried out, the display shows a blinking “rESEt” while it is being applied and the equipment is disabled. This error RESET type is only accepted when no energy is given. Normally, do not use the external ERROR RESET. An abusive use may degrade the installation if the error is serious and occurs repeatedly. The AUTORESET function is secure and reliable. 10.1.3. Exceptions The following groups of errors are exceptions to the above-mentioned: NON-RESETTABLE Errors. This error group cannot be reset, neither with the AUTORESET function, nor with EXTERNAL RESET. These are the group of error of parameters (Err 0b, Err bx). When it appears for the first time, the equipment will be left into out of service and it will not admit any kind of error RESET, neither AUTORESET nor EXTERNAL RESET. Correct all the possible errors of parameters. Errors with automatic AUTORESET. Regardless of parameter CNF.02 right digit value, the errors belonging to this group are automatically reset. Therefore, as soon as the error cause disappears, it disappears too and the AUTORESET function counter does not increase. They can be referred as infinite or uncountable errors. When an error belonging to this group occurs, the inverter will never be out of service. The errors with automatic AUTORESET are: 0E (uncontrolled opening of contactors), 04 (low voltage), 07 (C1-C2 open), 18 (brake open when it should be closed), 19 (brake closed when it should be open), 5 (incremental/sinusoidal encoder error), 51 (error of absolute position reading). For further information about these errors, refer to the section 10.3 of the present chapter. Autotuning errors (Ax) and errors of sensors adjustment (dx). Regardless of parameter CNF.02 right digit value, these are errors for which the maximum number of errors of the AUTORESET function is 1. Therefore, if only one error appears, it will leave the inverter out of service.

DESCRIPTION Current sensor Error

CAUSE At least one of the current sensors has stopped working properly.

SOLUTION Before every starting, the inverter checks the current sensors. When starting, if the error 01 appears, we will make the following check: The data viewings int r and int S while inverter is stopped

01

NO

The difference between both values might be greater than 50 and/or the absolute value of one of them greater than 100. If this is the case, you should replace the inverter.

Over-current

02

A working situation where the motor instantly consumes a current above the maximum one supplied by the equipment has been detected.

NO

Anyway, if you have any questions or some questions to make, contact MP for support. This error is always a side effect of very serious problems such as: Power cables incorrectly connected, faulty contactor, encoder with occasional failures, too sudden acceleration or deceleration, machine wheels with high inertia ... Find the failure. The repetitive occurrence of this failure may cause the equipment’s destruction. If you cannot solve it, please contact MACPUARSA and describe the failure situation in detail.

High capacitors’ voltage

03

The maximum capacitors’ voltage allowed has been exceeded either in idle state or in operation.

1. Check voltage applied to the equipment. EXCESSIVE VOLTAGE MAY DESTROY EQUIPMENT. IF 400 Vac IS APPLIED TO THE 220Vac EQUIPMENT, IT WILL BE COMPLETELY DESTROYED. 2. Check both the braking resistance connection and that it is in perfect condition (by measuring ohms between its terminals).

NO

When working in regenerative operation (as a generator), capacitors’ voltage increases and voltage is restricted by braking resistance. If the latter is not connected, Err 03 will be displayed.

CAUSE

Low capacitors’ voltage

The capacitors’ voltage is below the minimum accepted by the equipment, either in standby or in operation. In rescue mode, low battery voltage.

Minimum capacitor voltage levels: 400 Vac: 500 Vdc Stopped; 450 Vdc Running 230 Vac: 250 Vdc Stopped; 220 Vdc Running

SOLUTION In normal mode: 1. Check voltage applied to the equipment. Insufficient voltage may prevent the equipment from starting. Provisional connection, heavy machinery near the installation, etc. are possible causes for this error. 2. Like error 02, it may be due to third causes: Power cables incorrectly connected, faulty contactor, encoder with occasional failures, too sudden acceleration or deceleration, machine wheels with high inertia ... In rescue mode with 4/5 batteries

Minimum battery voltage levels (400 / 230 Vac):

1. Make sure the batteries have been charging for at least 24 hours.

As a whole, 50 Vdc Stopped; 45 Vdc Running 04

YES

For each battery: 12/13 Vdc. If voltage drops below 8 Vdc or raises above 16/17 Vdc, replace the unit immediately.

2. Check overall voltage in all batteries and unit voltage of each of them. 3. Check wiring in inverter’s batteries. 4. Check that, in normal mode, batteries are charging and 60 V CARBAT board/48 V CHARGER work normally. In rescue mode with UPS (WITHOUT batteries) 1. Make sure the UPS have been charging for at least 24 hours. 2. Check that the continuous bus voltage (CE-, CE+), in rescue mode is above 300 Vdc (220 rectified Vac). 3. Check the rescue system’s wiring. 4. Check that in, normal mode, UPS is ON and charging.

SOLUTION

2) Machine speed is under target speed or zero (only for synchronous if TR0.03 ≠ 0).

2. If the car is overloaded and the lift is not correctly counterweighted, or if the car or counterweight locking has occurred, the inverter cannot start the machine and this error will be displayed. 3. Motor not connected or wrongly connected with, at least, one phase missing. 4. Incorrect parameterising of the inverter. The most common parameters which may cause this error are ENC.00 (pulses per turn) and DRI.03 (number of machine poles). 5. Encoder offset not adjusted. Either the encoder has been replaced or, due to an incorrect encoder to rotor coupling, it has misadjusted. The encoder coupling must be secured/checked and then run autotuning.

ASYNCHRONOUS Motors: 1. Operating in open-loop control. It may be due to parameter INT.01 being excessively low and, on applying an important load to the car, the lift does not start. 2. Operating in closed-loop control. It may have been configured as closed-loop control and the encoder is not connected or the inverter is not detecting its pulses. The equipment will consider speed 0 and apply maximum current. 3. Check that the brake activates correctly. 4. If the car is overloaded and the lift is not correctly counterweighted, if the car or counterweight locking has occurred, the inverter cannot start the machine and this error will be displayed. 5. Incorrect parameterising of the inverter. The most common parameters which may cause this error are ENC.00 (pulses per turn) and DRI.03 (number of machine poles).

DESCRIPTION

CAUSE

SOLUTION

Power terminals C1 – C2 not connected

The terminals C1 and C2 must be shorted (with power cable) as long as the inverter is supplying energy. If it disappears instantly, the error is generated.

Refer to chapter 5, section 5.2: to know how to make the bridge between C1 - C2 and K1 and K2 contactors. Check the connections.

Short circuit

A short circuit has been detected in the motor output (U, V, W) or in the braking resistance.

Check phases U, V, W from the inverter’s output to the machine’s connection.

A contactor’s power contact may also be damaged.

08

NO Check that braking resistance is in perfect condition by measuring resistance between its terminals. Overtemperature

09

Over-temperature is due to a high rate working situation, with long approach speed sections and high room temperature. This error, unlike the others, remains on display for 1 minute. This is to cool down the inverter.

NO

1. Try to reduce the approach speed section and then operate in closed-loop (consumption is lower). 2. The equipment’s fans may deteriorate (although very unlikely); please observe if, on the inverter supplying energy (lift in motion), the fans remain stopped. If this is the case, replace the equipment. 3. Check that the brake activates correctly.

0E

YES

Uncontrolled contactor opening

Motor not connected 10

During a service execution, the EMERGENCY STOP signal disappeared (terminal no.12); that is to say, contactors K1 and K2 were unexpectedly deactivated.

There is no charge connected to the frequency inverter output.

Normally, this error occurs when a contact in the safety chain is unexpectedly activated during a service execution. In MACPUARSA controllers, in inspection operation, the series suddenly activate when a movement is interrupted. This causes error 0E to be displayed after each inspection movement. Check power wiring from inverter’s output (U – V- W) to motor terminals.

NO Check that the motor is in perfect condition (by measuring resistance between phases).

It can occur in faulty motors, when there is car overload, in machines with inertia drive ... If the equipment is incorrectly parameterised, this error may also occur. The most common parameters which may cause this error are ENC.00 (pulses per turn) and DRI.03 (number of machine poles). In synchronous motors with parameter TR0.03 ≠ 0, this error may occur in the following situations: 1) Autotuning has been run with the machine empty. Furthermore, the inverter has been parameterised with the corresponding profile. Run the machine and, after a brief vibration/rumble, error 11 (or 14) will occur. The reason is the machine is empty and the profiles have been created for loaded machines. Once sure that the autotuning process has been completed, place the load and test it. 2) The machine is loaded, a brief vibration/rumble is noticed and error 11 (or 14) occurs. This is normally due to incorrect parameterising of the speed control, filter and/or position control. In this case, use the profile corresponding to this machine.

DESCRIPTION Reverse overspeed

CAUSE Lift is moving on the opposite direction to the wanted one and faster than expected.

SOLUTION This error can occur in the following situations: 1) If the equipment parameterisation is wrong, this error can appear. The most common parameters that may cause this error are ENC.00 (pulses per revolution) and DRI.03 (poles number of the machine).

14

2) An autotuning has been run when the machine was working with no load hanging from the pulley. In addition, the inverter has been parameterised with the right profile. We make the machine work and, after a short vibration/rumbling, the inverter issues error 11 (or 14).

NO

This is because the machine has no load hanging and the profiles are designed for machines with load hanging. If we are sure that the autotuning has finished successfully, we will hang the load and make the test. 3) The machine has load hanging, after a short vibration/rumbling, the error 14 (or 11) appears. Usually, this is due to a wrong parameterisation of the speed control, the filter and/or the position control. In this case, apply the right profile for this machine. Invalid contactor state

16

The inverter has detected that contactors are closed when it is stopped.

NO

If you get this error, do the following check: 1)

Set the third digit from right of parameter CNF.02 to 1.

2)

Unplug connector XC13 from the inverter.

3)

Make the lift run, either in normal mode or MES mode or inspection mode.

CAUSE

Overvoltage (open loop only)

The inverter has exceeded the voltage limit applied to the motor and the current does not reach the starting current (INT.01).

SOLUTION Possible causes: 1)

Current sensors in bad conditions. If you have the current sensors checking disabled, you can enable it by setting the 4th digit from right of parameter CNF.02 to 0. By doing so, the inverter will check the state of the sensors at starting. Also, while inverter is stopped, you can view the int r and int s data. Their values must be between -50 and +50 and the difference between them must be less than 100.

2) 17

NO

Starting current too high (INT.01). This parameter value must never exceed the rated current indicated on the machine’s nameplate. Usually, it must be between the 50% and 75% of the rated current, depending on the installation.

3)

Motor not connected. Check there is continuity of phases from the inverter up to the machine.

4)

Motor stator resistance too high. Measure the resistance between the machine phases. Normally, it should not exceed 12 Ohms in induction machines. Contact MP for support.

It is very important to be sure of this value. A wrong value in this parameter may cause the car overspeed. It has to be done at this moment in order to proceed with the encoder check later on. We will have to set DRI.03 to the number of motor poles. Usually, its value is 4 which is the default value for this parameter. However, if you want to be sure, we recommend referring to the nameplate machine.

TABLE 11.5 11.3. Check of encoder, current sensors and run direction We will carry out the following actions: 1. Set the type of control in open-loop (CNF.00 = 0). 2. Set the control board in inspection mode. 3. Press the upwards (or downwards) button of the inspection command. If it runs up (or down), i.e., if the movement direction is the reverse of the commanded one, there is a problem machine phases’ order. In this situation, we will have to: a) Switch off the inverter (for safety), and, in the mains connection cable from the machine to the controller, make the exchange of U and V phases. b) Switch on the inverter and retry to press upwards (or downwards) button. If the inverter is going to run in open-loop (WITHOUT ENCODER), go to point 10 (end of the process). 4. Activate the test mode (CNF.05 = 1). 5. With the inverter stopped, we can see: · Or, tESt, blinking every two seconds. After it is seen three times, we determine that, for the moment, everything is correct. · Or, tSt01 blinking. Contact MP. 6. Make an upward travel and another one downward, as the encoder check is possible only when the machine is in movement. · If during both travels tSt02 does NOT appear, at any point, the encoder is correct. Go to point 8. · If at some point during the execution of these travels, tSt02 appears, it is because there is a problem with the encoder. Go to point 7. 7. Deactivate the test mode (CNF.05 = 0) and display the "Encod" value. The "Encod" viewing value is a counter with a range from 0 to 65535. If the value is increasing, when it reaches 65535, it will return to 0, and it will go on increasing. If the value is decreasing, when it reaches 0, it will return to 65535, and it will go on decreasing.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter We have to ensure the following conditions in the following situations:

• Stopped. We will visualize the "Encod" value. We will touch the encoder connector; we • •

will smoothly pull the cables. The value should remain at 0. If not, the encoder connection shall be checked. Upwards. The "UEL" visualisation must be a positive value and very close to "FrEC", the "E5" visualisation must be also positive and close to "FrEC" and the value of "Encod" counter shall be decreasing. Downwards. La "UEL" visualisation must be a negative value and its absolute value very close to "FrEC", the "E5" visualisation must be also negative and its absolute value close to "FrEC" and the value of "Encod" counter shall be increasing.

If the visualisations "UEL" and "E5" have similar values and opposite sign and “Encod” behaviour is the reverse of the described one when moving upwards or downwards and, when stopped, it remains to 0, we have to exchange C1+ by el C1-, in six-pole female Wago connector XENC of the encoder, and repeat the test. In any other case, there is a problem with the encoder. The most common problems related to the encoder are: - One or more cables of the encoder signal do not contact, because when inserting the cable in the Wago connector, it "bites" the plastic sleeve instead of “biting” the cable. - Confusion in the connection order of the cables in the connector. - Absence of encoder supply. In this case, when moving, the value of "Encod" visualisation remains to 0. Once the required checks have been done, we will reactivate the test mode (CNF05 = 1) and return to point 5. 8. Deactivate the test mode (CNF.05 = 0). 9. ONLY if the lift is going to operate in closed-loop control (using the encoder), restore CNF.00=1. 10. End of the check. 11.4. Adjustment of INT.00 and INT.01 1. Set the control type in open-loop (CNF.00 = 0). 2. Determination of the starting current (INT.01). This step applies only if the inverter is going to run in open-loop mode. If it going to run in closedloop mode, go to point 3. These are the steps to be followed: a) Carry out a downwards service without load from the highest floor. If it is unable to start, we will slowly and gradually increase INT.01 until the starting is achieved. Do not overdo. After reaching this, proceed with next point. b) Carry out a downwards service with load from the highest floor. If it is unable to start, we will slowly and gradually increase INT.01 until the starting is achieved. Do not overdo. 3. Determination of the no-load current (INT.00). In open-loop and closed-loop. Even if the inverter is going to run in open-loop, the parameter INT.00 has to be properly adjusted to let the inverter carry out the proper unbalanced load. The process to be followed is the following:

• Executing long services, we will make the lift operate without load in car. • When it is moving at rated speed, read the "int d" magnitude. • Make the reading both upwards and downwards. The obtained result in both cases will be quite similar.

• Set INT.00 to the LOWER of the two readings. 4. ONLY if the lift is going to operate in closed-loop control (using the encoder), restore CNF.00=1.

TR2.00

are

the

rated

Depending on the control type selected through parameter CNF.00 (0: open-loop; 1: closed-loop), these data will be son interpreted like frequencies or speeds, respectively. Let us suppose an inverter configured in closed-loop control, with TR1.00 = 50.00. We give the rated speed command to it. It makes the acceleration curve properly, it reaches the rated speed and, after 1 or 2 seconds, it starts vibrating, vibrations that, depending on the case, can be very strong. Why does it occur? As already mentioned, if the inverter is configured in open-loop control (CNF.00 = 0), the value stored in TR1.00 represents the target electrical frequency of output to motor and, if the inverter is configured in closed-loop control (CNF.00 = 1), TR1.00 is the target mechanical frequency, which is not the electrical frequency of output, due to the inherent sliding to asynchronous machines. Therefore, if the inverter is configured in open-loop, the value we have to record in parameter TR1.00 is the rated frequency in hertz shown in the machine’s nameplate. If the inverter is configured in closed-loop, we have to calculate the following formula:

RPMxPoles No. 120 On the machine’s nameplate, the rated revolutions per minute (RPM) and the number of poles shall be stated. With these data and applying the following formula, we obtain the maximum value to be recorded in TR1.00 and TR2.00. The formula considers the number of poles, not the pairs of poles. For instance, let us suppose a machine with 4 poles 1350 rpm in its nameplate. The value to be recorded in this parameter would be:

RPMxPoles No. 1350 x 4 = = 45.00 120 120 There is a formula to calculate TR1.00 which is normally used:

RPM x50 Hz 1500 Two conditions are required for this formula to be valid: 1) The machine rated frequency must be 50Hz 2) The machine must necessarily have 4 poles. Even if it is not usual, there are machines of 6 poles. In these cases, this formula cannot be used. 11.6. Adjustment of low speed (TR1.01) The steps to be followed are: - Initial value of TR1.01 (approach speed).

V0.01 – 04/2013

101

The initial value of TR1.01 can be taken from the following table: Speed (m/s)

3..4 TABLE 11.6

This table is based on experimental results. In most of the cases, with these values, good results have been obtained. Therefore, we are going to use the table to set a first value. However, we can say that the approach speed is obtained on the basis of the linear speed. This one is to be around 10-12 cm/s. For instance, a frequent case: Leo Sassi machine of 1 m/s and regulation frequency of 45 Hz:

10 cm/s x

45 Hz 45 Hz = 0.10 m/s x = 4.5 Hz 1 m/s 1 m/s

If we apply this formula in all the other cases, taking 45/48 Hz as rated speed, we will see that it is the rule to follow. - Vibrations When setting the values from the table, it may be that we obtain vibrations in approach. It happens quite often in lifts of 1.6 m/s. We will increase TR1.01 in 0,5 Hz increments until the vibration disappears. 11.7. Adjustment of S-curves The speed is defined as the position change with respect to time - first derivative of position. The acceleration is defined as the speed change with respect to time - first derivative of speed or second derivative of position. The jerk is defined as the acceleration change with respect to time - first derivative of acceleration. Our sensitivity is associated to this magnitude, i.e., to the acceleration changes and it can cause an unpleasant sensation to the lift car passengers when starting and stopping. Therefore, in these points (starting and stopping), we have to assign the speed setpoints to the motor in such a way to obtain smooth changes of acceleration. The speed profile obtained this way is called S-curves. In the following figure, we can see the profiles of speed, acceleration and jerk for a linear curve and an S-curve.

FIGURE 11.2 The higher is the value set in parameters RSN.01-RSN.04, the higher is the gentleness in the associated area. IMPORTANT NOTE: When we use this type of curves, the acceleration time TR1.02 and deceleration time TR1.04 are affected by constants RSN.01-RSN.04. We could say that the set values in TR1.02 and TR1.04 could be the acceleration and deceleration times if parameters RSN.01-RSN.04 were set to 1. As these parameters are being increased, the times of acceleration and deceleration are being increased as well.

FIGURE 11.3 11.7.2. Sinusoidal curves These curves are called sinusoidal because the acceleration and jerk profiles are sinusoidal. A big difference with respect to standard curves, important to bear in mind, is that this type of curves scrupulously observes the times of acceleration (TR1.02) and deceleration (TR1.04), using exactly the time indicated by these parameters, neither more nor less. Therefore, if the set values in these parameters are too low, it can happen that we obtain errors like Err 04 (low voltage of capacitors), Err 02 (over-current) or Err 13 (instable voltage of capacitors). To solve this problem, just increase TR1.02 and/or TR1.04. The standard curves are also called partial S-curves, as we begin from a linear acceleration and we modify, one by one, the areas of speed slope change by means of constants. The sinusoidal S-curves are also called full S-curves, as the obtained speed curve corresponds to a unique function that depends on the initial speed, final speed and acceleration or deceleration time. It means that 3VFMAC-DSP 6P determines the full curve for these parameters. There is just one issue more to be treated: modification factor for acceleration curve (TR1.03, TR1.05). The modification factor is nothing more and nothing less than a "deformation" of the curve, in such a way that:

• the higher the value, the softer the beginning of the curve and the harder at the end and vice versa, and

• the lower the value, the less gentle the beginning of the curve and the softer at the end.

V0.01 – 04/2013

104

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

The value that does not "deform" the curve (neutral value) is 1. The most convenient is to smooth the acceleration at low speeds. Therefore, the default value TR1.03 (modification factor for acceleration) is 1.50. 11.7.3. Which curve type do we have to choose? Whenever it is possible, the sinusoidal S-curve (default value): the obtained jerk is lower than the resulting one from standard curves. 11.7.4. Adjustment process for standard curves in open-loop mode 1. Adjustment of the acceleration curve: TR1.02, RSN.01, RSN.02 The adjustment of the acceleration curve corresponding to the standard curves consists of the adjustment of 3 parameters:

• TR1.02 (acceleration time) • RSN.01 (constant of acceleration beginning) • RSN.02 (constant of acceleration end) These three parameters have to be simultaneously adjusted. Let us remind, as already mentioned in section 11.7.1. Standard curves of this document that the acceleration final time depends on these 3 parameters, because TR1.02 is affected by the constants RSN.01 and RSN.02: the higher these constants, the gentler the beginning and the end of the acceleration and the longer the final time invested. The values set in these parameters will be a compromise between the required comfort during the acceleration curve and the final time invested in the acceleration. The default values for these parameters are TR1.02=2.50s, RSN.01=50, RSN.02=50. 2. Adjustment of the deceleration curve: TR1.04, RSN.03, RSN.04 The adjustment of the deceleration curve corresponding to the standard curves consists of the adjustment of 3 parameters:

• TR1.04 (deceleration time) • RSN.03 (constant of deceleration beginning) • RSN.04 (constant of deceleration end) These three parameters have to be simultaneously adjusted. Let us remind, as already mentioned in section 11.7.1. Standard curves of this document that the acceleration final time depends on these 3 parameters, because TR1.04 is affected by the constants RSN.03 and RSN.04: the higher these constants, the gentler the beginning and the end of the deceleration and the longer the final time invested. Once the approach frequency is reached, it is important it remains stable for a time between 1 and 3 seconds. To do this, we will use the viewing “FrEC” where an "E" must be displayed for more than 1 second and less than 3: - If it is displayed for less than one second, we can:

• Or reduce the deceleration time (TR1.04). We have to do this carefully because a • •

too low value in this parameter can cause Err 02, Err 04 or Err 13. We will do this by decreasing 0.20 seconds at a time. Or slightly reduce RSN.03 without compromising the comfort at the deceleration beginning, by using decreases of 20 units. Or slightly reduce RSN.04 without compromising the comfort at the deceleration end, by using decreases of 20 units at a time.

The default values for these parameters are TR1.02=2.50 s, RSN.01=50, RSN.02=50. 2.

- If it is displayed for more than three seconds, we will increase the deceleration time, by increases of (TR1.04) of 0.20 seconds, until reaching the indicated range. 4. Adjustment of the modification factor for deceleration: TR1.05 This parameter affects “only” the profile of the target speed during the deceleration:

• the higher the value, the softer the beginning of the curve and the harder at the end and vice versa, and

• the lower the value, the less gentle the beginning of the curve and the softer at the end. When we say that it affects only the speed profile, we mean that it does not affect the deceleration time: it does not increase or decrease it. Its default value is 1.00. 11.8. Adjustment of levelling 11.8.1. Stopping time (RSN.05) The parameter RSN.05 is the stopping time: i.e., how long it takes to the lift to get from the approach speed to speed 0. Values with milliseconds accuracy can be introduced. The stopping S-curve is ALWAYS sinusoidal type -with modification factor 1.00, independently of the S-curve type selected (RSN.00 = 0 or RSN.00 = 2). The unique parameterisable datum of the stopping curve is the time. It has been designed like this because, as already mentioned in previous section, the sinusoidal curve jerk is much lower than the standard curve one. 11.8.2. Load compensation (RSN.06) The function of parameter RSN.06 is to compensate "somehow" the load during the stopping. In open-loop operation, this "somehow" consists of setting out as stopping time a factor higher or lower than RSN.05 and setting out as approach speed a factor higher or lower than TR1.01, factor which is determined by the inverter according to the torque exerted by the motor. In closed-loop operation, this "somehow" consists of increasing or decreasing the stopping time according to the torque which is being exerted at that moment.

• The neutral value for this parameter is 100 which is also the default value. Neutral value means that with this value the stopping time will be exactly the one set in RSN.05.

• The higher than 100, the lower the stopping time according to the load. • The lower than 100, the higher the stopping time according to the load. 11.8.3. Load compensation and levelling adjustment The aim of the levelling adjustment process is not the exact levelling with floor level; the real aim is to achieve a uniform stopping point (always the same) independently of the load, either up or down service. Once this is achieved, the levelling magnets will be moved in order to make the lift stopping point coincide with the floor level. Hereafter, the sequence of the actions to be carried out in order to achieve the levelling adjustment is explained. These actions must be made according to this sequence, because if the order is modified, it will be very difficult to achieve a proper levelling of the lift. The adjustment procedure is different whether the installation is going to operate in open-loop (without encoder) or in closed-loop (with encoder).

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 11.8.3.1. Load compensation and levelling adjustment in open-loop (without encoder) 1. Load compensation (RSN.06): If it is required, here are the steps to follow: a. Set RSN.06 to a value between 130 and 140. b. Choose a destination intermediate floor (D) c. Choose a departure floor in such a way that: - It is located above the destination floor D - It is not the highest floor - There are at least two levels until the destination floor D d. Make a travel from the departure floor A until D, WITHOUT LOAD. e. Make a travel from the departure floor A until D, WITH LOAD. f. Analyse the obtained result for the runs carried out: Gradually increase - if we fall short- or decrease - if we exceed- until achieving the appropriate levelling. In open-loop, you do not get a perfect levelling (whereas in closed-loop, you get it), so that deviations of +/- 1 cm must be admitted. If it is not achieved, slightly slow down the approach speed TR01.01, but never adjust with lower values than 4.2 Hz. Once RSN.06 or TR1.01 is modified, return to point 1.d. 2. Levelling in up direction and in down direction (Adjustment of RSN.05) a. Choose a destination intermediate floor (D) b. Choose a departure floor A in such a way that: - It is located above the destination floor D - It is not the highest floor - There are at least two levels until the destination floor D c. Choose a second departure floor B in such a way that: - It is located bellow the destination floor D - It is not the lowest floor - There are at least two levels until the destination floor D d. Make a travel from the upper departure floor A until D, WITHOUT LOAD. e. Make a travel from the lower departure floor B until D, WITHOUT LOAD. f. Analyse the obtained result for the runs carried out: - In the downwards service (d), if we obtain a stopping point higher than the one obtained after the upwards service (e), increase RSN.05 slightly and gradually, by increases of 0.050 seconds (for example: from 0.800 to 0.850). Once RSN.05 is modified, return to point d.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter - In the downwards service (d), if we obtain a stopping point lower than the one obtained after the upwards service (e), decrease RSN.05 slightly and gradually, by decreases of 0,050 seconds (for example: from 0.800 to 0.750). Once RSN.05 is modified, return to point d. - If the levelling point coincides in both cases (d, e), proceed to relocate the level magnets. 3. Relocation of level magnets Previous adjustments enable to make the lift stop at the same point, with or without load, and in up direction or in down direction. Then, we just have to make that (already uniform) point coincide with the floor level. To do so, duly move the magnets which determine the levelling point at each floor, and correct the existing deviations at every stopping. NOTE: If there is any case where the modification is higher than 5 cm, the points of deceleration beginning (pulse magnets) will have to be modified in order to keep constant the deceleration section and the approach section to floor. Finally, we must check that the distance between the approach magnet and the stopping magnet of the destination floor D selected at 3.a is the same at all the other levels. 11.8.3.2. Load compensation and levelling adjustment in closed-loop (with encoder) 1. Adjustment of parameter VEL.10, if required If the machine makes a throaty noise when stopping, we must set the second digit - from right of parameter VEL.10 to 1. This is to say, assuming that its value is the default one 01000, we will have to set it to the value 01010. This parameter can only be modified with the advanced access code. 2. Load compensation (RSN.06): Optional Normally, when operating in closed-loop -with industrial encoder or with magnet encoder -, no there is no need to modify this parameter, because in this mode the load is automatically compensated. If it is required, here are the steps to follow: a. Choose a destination intermediate floor (D) b. Choose a departure floor A in such a way that: - It is located above the destination floor D - It is not the highest floor (superior) - There are at least two levels until the destination floor D c. Make a travel from the upper departure floor A until D, WITHOUT LOAD. e. Make a travel from the lower departure floor B until D, WITHOUT LOAD. f. Analyse the obtained result for the runs carried out: - If the levelling point is the same in both cases (c, d), proceed to next point (3). - Otherwise, increase RSN.06 in increases of 5 units. With the inverter operating in closed loop, never exceed 120.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter Once modified, return to point 2.c. 3. Readjustment of TR1.01: Optional The aim of the readjustment of TR1.01 is to make a first rough approximation of the distance between the magnetic reader and the magnet, leaving RSN.05 for the fine adjustment. Thus, once adjusted, the value of the stopping time parameter RSN.05 would be neither too high nor too low. In some cases, too high could cause problems in stopping with full load. Too low could cause an abrupt stopping. To carry out this adjustment phase, a person will get on the car roof to take the required measurements. The steps to follow are: a. Choose a destination intermediate floor (D) b. Choose a departure floor A in such a way that: - It is located above the destination floor D - It is not the highest floor - There are at least two levels until the destination floor c. Choose a second departure floor B in such a way that: - It is located bellow the destination floor D - It is not the lowest floor - There are at least two levels until the destination floor D d. Make a travel from the upper departure floor A until D. Measure the distance from the magnet beginning up to the place where the magnetic reader is, as shown in the figure.

Once RSN.05 is modified, return to point d. - If the levelling point coincides in both cases (d, e), proceed to relocate the level magnets. 5. Relocation of level magnets Previous adjustments enable to make the lift stop at the same point, with or without load, and in up direction or in down direction. Then, we just have to make that (already uniform) point coincide with the floor level. To do so, duly move the magnets which determine the levelling point at each floor, and correct the existing deviations at every stopping. NOTE: If there is any case where the modification is higher than 5 cm, the points of deceleration beginning (pulse magnets) will have to be modified in order to keep constant the deceleration section and the approach section to floor. Finally, we must check that the distance between the approach magnet and the stopping magnet is the same at every single level. 11.9. Adjustment of short floors 11.9.1. What is a short floor? The notion of "short floor" within the inverter context is different from the notion of "short floor" within the control board context. Here, we talk about "short floor" from the inverter point of view when the rated speed is not achieved during a service. It may occur because:

• •

it is a particularly short floor, or during the service between adjacent floors, the rated speed is not achieved. This is the most common case. It happens in those lifts working at 1.6 m/s or 1.0 m/s, with large acceleration sections.

This circumstance can be appreciated in the value of the viewing "FrEC" which falls short of reaching the rated speed. 11.9.2. Adjustment aim When configuring a "short floor", the main aim is that the time elapsing at low speed is not excessive, in such a way that the service would take longer than required. In open-loop, to quantify this time, we will observe that the programmed approach frequency (TR1.01) is kept in the viewing "FrEC" for 2 or 3 seconds. More than 3 seconds is considered excessive. In closed-loop, to quantify this time, we will observe that a fixed "E" on the first digit -from left- is kept in the viewing "FrEC" for 2 or 3 seconds. More than 3 seconds is considered excessive.

11.9.3. How to adjust a short floor? There are two parameters, both in group RSC (Short S-Ramp), to adjust short floors: RSC.00 and RSC.01.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

FIGURE 11.6 When the inverter meets the signal of approach frequency, it will make the following:

• It will go on with the frequency ramp a “little more”, i.e., it will go on increasing the frequency a “little more”. -

-

For standard S-curves, this “little more” is automatically calculated by the inverter according to the acceleration time and the cut off frequency, in the same way its predecessor, el 3VFMAC1, did it. For sinusoidal S-curves, this “little more” is quantified by parameter RSC.01. By default, it is set to a value of 50. The longer RSC.01, it will go on increasing the frequency for longer and, therefore, the shorter approach time.

• After completion of the frequency ramp, it can keep the frequency reached for a certain time which will be calculated from the RSC.00 parameter value: RSC.00 is the time during which the final frequency of the ramp cut off is going to be kept if the latter was half of the rated frequency. Thus, the higher the frequency at the end of the cut off ramp, the shorter the extension time and vice versa, the lower this frequency, the longer the extension time. Thus, the tendency is always to achieve the set objective: reduce the time at low frequency. The formula is the following one:

TR1.00 x RSC.00  CUT OFF FREC/SPEED    2   For instance: let us suppose that TR1.00 = 50.00 Hz and RSC.00 = 1.000 s. CUT OFF FRECUENCY 12.5 Hz

2.000 s

25.0 Hz = TR1/2

1.000 s = RSC.00

37.5 Hz

0.667 s

50 Hz

0.500 s

Extension Time

TABLE 11.7 Parameter RSC.00 applies for both types of curves (sinusoidal and standard). Nevertheless, when selecting Sinusoidal S-curves (RSN.00 = 2), it is usually set it to zero (RSC.00 = 0.000), because the adjustment of RSC.01 may normally be enough.

PICTURE 12.1 b) Control board connection. We will have to take into account if the control board is Via Serie, MicroBasic or non-MP. •

If the control board is VIA SERIE, the commands are given through the connector with flat cable XC10 and the connector XC2 must have NO terminal connected. Important points when checking the connection of the flat cable in connector XC10: - DO NOT CONNECT IN XC11 OF THE INVERTER - The flat cable has to be connected in the connector X3VF of the Via Serie board and its red part has to be on the left side, according to its position in the controller seen from the front. - The flat cable has to be connected in XC10 of the inverter with its red part facing upwards, according to its position in the controller seen from the front.

•

If the control board is MICROBASIC or non-MP, the command orders will arrive to the inverter through the voltage-free contacts of the connector XC2. When replacing a 3P inverter by a 6P inverter, follow the instructions given in the document called “3VFMAC-DSP replacement guide”.

If the reading of brake microswitches is enabled (refer to section 12.1.2.2), it will come through terminal 19 of connector XC2, for both Via Serie and MicroBasic. Therefore, these are the two cases that can occur when the reading of brake microswitches is enabled: • •

Standard rectifier RECT_01: activation and holding voltages are the same and it provides 200 Vdc (schema 12.2).

SCHEMA 12.2 The schemas show the references (1), associated to the brake-varistor filter, and (2), associated to the reading of brake microswitches. These two issues will be developed in next sections. 12.1.2.1. Brake-varistor filter Due to the electrical features of the brake activation circuit and by the very nature of the brake coil, a brakevaristor filter is required, because of voltage peaks that occur when deactivating the brakes. Its function is to ensure the electrical protection of the controller’s elements against these voltage peaks. The filter MUST be connected to terminals (3) and (4) of the connector XMAQ, at the end connected to the machine, NEVER at the end connected to the controller. IMPORTANT THE APPROPRIATE VARISTOR-FILTER IS COMPULSORY. OTHERWISE, IT CAN CAUSE THE DESTRUCTION OF THE ELECTRICAL /ELECTRONIC ELEMENTS. Should you have any doubt or need support, contact MP. 12.1.2.2. Brake microswitches The reading of brake microswitches is optional, but highly recommended. If carried out, such a reading will be done only through terminal 19 of connector XC2. As already mentioned in section 12.1.1, if the reading of brake microswitches is enabled, it will be carried out through terminal 19 of connector XC2, for both Via Serie and MicroBasic control boards. Therefore, these are the two cases that can occur when the reading of brake microswitches is enabled: • If the control board is Via Serie, the connector XC2 will only and exclusively have terminals 11 and 19 wired and connected. • If the control board is MICROBASIC or non-MP, all the terminals must be wired, including, of course, terminal 19.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter The reading of brake microswitches can be monitored through the state of LED 19. 3VFMAC-DSP 6P can be configured in three different ways, depending on the value of parameter STC.08: 0: Reading of brake microswitches disabled. Function RESET ERROR of terminal 19. 1: Reading of brake microswitches with normally open logic. 2: Reading of brake microswitches with normally closed logic. Synchronous machines are provided with two microswitches, one for each brake disc included in this type of machines. Depending on the model and/or the manufacturer, the brake microswitches can be wired in three different ways: 1) Common signal + NC contact for both brake microswitches. 2) Common signal + NO contact for both brake microswitches. 3) Common signal + NC contact for one of the microswitches + NO contact for the other one. As pointed out earlier, 3VFMAC-DSP 6P carries out the reading of brake microswitches via a single terminal. Therefore, we will have to wire the microswitches both together, in series or in parallel with the required logic according to which we will set the appropriate value in STC.08. As shown in previous schemas 12.2 and 12.3, terminals 5 and 6 of controller’s connector XMAQ are directly wired to terminals 11 and 12 of connector XC2, respectively. IMPORTANT NOTE: If the inverter input is connected to the brake microswitches, we must be sure that parameter SCT.08 is appropriately configured. If STC.08 = 0 and the reading is wired to terminal 19, it can happen that the inverter never starts, even though receiving the RUN command. In this particular case, everything would be solved by disconnecting terminal 19 of XC2. 12.1.3. Encoder The encoder coupled to a synchronous machine is very different from the industrial encoder coupled to an asynchronous machine. As a matter of fact, they are different devices: an absolute encoder a sinusoidal encoder. The absolute encoder provides to the inverter a fixed and determined position in one complete turn with a resolution of 8192 points. The absolute position reading is based on a physical interface RS-485 through connectors XC5 (DATA channel, terminals T1, T2) and XC7 (CLOCK, terminals T3, T4).

PICTURE 12.2 The supported protocol is Endat01, proprietary Heidenhain. Errors associated to the absolute encoder are numbered as err 5x, i.e., 51, 51, etc. The sinusoidal encoder consists of two sinusoidal signals 1V peak to peak displaced in 90º to one another.

In addition, it is very important to check that the connection of the power source connector and the one of the adapter cable connector have the same sign: +, red and -, black. Check that the negative pole of the power source is connected to ground, as shown in the here below picture.

To connect the encoder to the inverter, an adapter cable is required. The encoder adapter cable provides the connection interface between the machine encoder and the inverter.

FIGURE 12.2 During the starting and stopping, the speed control reference will be set out by the position control. In any other situation, the reference speed will be set out by the module of S-curves. The position control configuration is carried out through the group POS parameters. The module of S-curves generates constantly the reference speed, plotting out a speed curve based on the TR1 group of parameters for the bank number 1 of speeds/acceleration and on the TR2 for the bank number 2 of speeds/acceleration and on the parameter RSN.05 (stopping time). We will have a reference current as output of the speed control. This current has to be filtered, in order to eliminate the typical mechanical resonances of the machine and of the installation. The involved parameters in the filter configuration are INT.09 and PEC.00. Finally, there is a current control. This module output will be the result of the output voltages to the motor in accordance with the reference current. This module parameterisation is one of the functions automatically carried out during the autotuning process. The parameters associated to this module are INT.03, INT.04, INT.05 and INT.06.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 12.2.3. Sinusoidal encoder check When switching on the inverter, after the starting process, if the inverter display shows err 05, we will have to: - Check that the main board is switched on. - Press the red button (PR) of the inverter - If the error persists, carry out following checks: 1) Check the encoder power supply (5 Vdc). 2) Check that the power supply negative terminal is connected to the ground. 3) Check the proper connection of terminals XC6 and XC8. 4) Check that the wires of the adapter cable going to connectors XC6 and XC8 do not “bite” the plastic. 5) Check that the cable length going from the machine encoder to the adapter cable is approximately 10 m. 6) Check the electrical continuity of the adapter cable (refer to table 12.5, figure 12.1). After all these checks are done, press the red button (PR) of the inverter. However, if the error 05 persists, contact MP for support. 12.2.4. Initial review of parameters The initial review of parameters will help us to set out baseline values with which a great part of the adjustment will already be done. These are the cases that may occur: 1. If the machine is included in the machine table (refer to section 8.4), we will use parameter DRI.08 to set out the values associated to the machine. 2. If the machine is not included in the machine table but we have its associated profile, the associated values will be set out by hand. These profiles can be consulted at ssp.macpuarsa.es. 3. If we know the parameters of another installation which is properly functioning with the same machine model, we can use those installation parameters. 4. Otherwise, i.e., if the machine is not included in the machine table, we have neither its profile, nor any other installation with the same machine model, we will have to carry out the autotuning process (section 12.2.6). 12.2.5. Absolute encoder check A. CHECK THAT THE ENCODER CABLE IS PROPERLY CONNECTED TO THE MACHINE ENCODER. Some encoders are supplied with a cable of 5 to 10 m, ending in a male DB15. Other encoders are provided with a cable of 10 cm, ending in a 12-poles M23 male connector. A cable of 5 to 10 m M23, female at an end and male DB15 at the other end is connected to this connector. In this case, the proper connection of 12-poles M23 male-female connectors must be checked. B. CHECK THE PROPER CONNECTION OF THE ADAPTER CABLE, ON THE ONE HAND, TO THE CABLE COMING OUT FROM THE ENCODER (TERMINAL DB15) AND, ON THE OTHER HAND, TO THE INVERTER TERMINALS (XC8, XC6, XC5 AND XC7); CHECK THE POWER SUPPLY CABLE AS WELL. C. CHECK THAT THE MAIN BOARD IS SWITCHED ON. The input voltage of the encoder power supply source comes from the main board. Therefore, if the main board is switched off, the error of absolute or sinusoidal encoder will be displayed. - If error 52 (or 51 at starting) occurs: 1) Check the proper connection of connectors XC5 and XC7 in the inverter. 2) Check that the Wago connectors do not “bite” the plastic. 3) Check the proper connection of the adapter cable to terminal DB15 of the encoder cable.

PICTURE 12.6 Press the red button (PR) of the inverter, twice in case of error 52, once in case of error 51. If the error persists, contact MP. - If error 58 occurs, there is discrepancy between the number of encoder turns and the inverter parameterisation. Contact MP Staff. - If an error between 53 and 57 occurs, the encoder is not right, maybe because internal errors are recorded or maybe because it is not the appropriate type. However, contact MP Staff. 12.2.6. Autotuning The autotuning process applies only to synchronous motors. The fundamental premise in order to run the autotuning process is that it must be carried out with no load hanging from the machine pulley. Therefore, the process execution requires the car and the counterweight to be hanged, and the cables removed from the pulley.

VERY IMPORTANT THE AUTOTUNING PROCESS’ EXECUTION IS MANDATORY IF AT LEAST ONE OF THESE TWO CONDITIONS IS MET: 1) THE MACHINE PROFILE IS NOT AVAILABLE. 2) IF THE ENCODER COUPLING HAS BEEN SOMEHOW MODIFIED.

Autotuning not only carries out the pole adjustment or zero adjustment. All the performed adjustments during the process are: 1. 2. 3. 4. 5. 6. 7.

Pole adjustment or zero adjustment. Configuration of the current control. Determination of the motor equivalent circuit. Adjustment values of the sinusoidal encoder. Determination of the number of poles. Determination of the number of pulses per encoder turn. Adjustment of motor direction/phases. The “Adjustment of motor direction/phases” involves “reconciling” the absolute encoder direction, the sinusoidal encoder and the phase connection order. Therefore, during the inverter installation, if the phase order is changed or if there were any change in the sinusoidal channels A and/or B, the autotuning process would detect the change and carry out the required adjustments.

Each group of these adjustments involves setting out the values of the parameters associated to each of them, as reflected in the following table:

In short, the autotuning process' execution generates values of parameters. Therefore, an inverter replacement does not involve the autotuning execution but the value migration of a group of parameters. Let us suppose that in an installation we replace the inverter by another one supplied from our Servicenter. Let us suppose the most common case: motor phases connected in the right order and the encoder channels as well. In this case, by means of the application MPConfig (reading/writing of parameters), we will read the parameters of the “old” inverter and we will write them on the “new” one. Doing so, the new inverter is now ready to operate. Another way to do so would be to record the machine profile by setting its appropriate code in the parameter DRI.08 (refer to section 8.4). The values of parameters DRI.04, DRI.05 and DRI.06 will not be modified. But these parameters ARE JUST FOR INFORMATION and do not have any effect on the machine control. Their values will only be modified as a consequence of the autotuning process' execution.

(*) The parameters relating to the speeds can be deduced from the rated frequency (Fn) or from the RPMs and the number of poles. (**)If the absolute encoder does not support Endat01 and/or the incremental encoder does not consist of two 1Vpp sinusoidal analogue channels, contact MP.

Process execution The execution and characterisation of the autotuning process is carried out through parameter TUN.00. To modify/execute this parameter, there is no need to enter with advanced code in SETUP mode. To command the autotuning process' execution, this parameter has to be set to the value 09999. After the process completion and as a result, if no error occurred over the course, we will set the values of a parameter group due to the adjustment and, in addition, the parameter TUN.00 itself will be set to zero. If any error occurs and/or the process is somehow interrupted, NO parameter will be modified. The modified parameters as a result of autotuning (TUN00=09999) are the ones related in table 12.6. Let us remind, as mentioned in previous section, that the autotuning process' execution requires noload hangs from the machine, the car and the counterweight are hanged, and the cables are REMOVED from the machine pulley.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter The autotuning execution consists of the following steps: * STEP 1: Set the control board in inspection or MES mode. * STEP 2: Check that the value of parameter DRI.07 corresponds to the machine rated current. The rated current value must be included on the machine’s nameplate. IMPORTANT NOTE: An erroneous value in this parameter may cause the machine deterioration. If this value is unknown or not available, the autotuning must not be carried out. * STEP 3: Check of speeds. This is basic for the machine proper functioning after the autotuning execution. TR1.00: Rated frequency. This datum can also be found on the machine nameplate. TR1.01: Approach frequency. As an initial value, set it to 10% of the rated frequency (TR1.00). TR0.00: Inspection speed. As an initial value, set it to 30% of the rated frequency (TR1.00). * STEP 4: Autotuning activation: Set TUN.00 = 09999. * STEP 5: Exit the SETUP mode. * STEP 6: The console must display, blinking and alternately:

* STEP 7: Keep pressing the up or down button of the rescue command or the inspection box. Along the process, the following message will appear, blinking:

t U n X X where XX represents the percentage of the completed process.

IMPORTANT: THIS IS THE MOMENT, NEVER BEFORE, WHEN WE CAN STOP PRESSING THE UP OR DOWN BUTTON, AS THE PROCESS HAS BEEN COMPLETED. * STEP 10: Stop pressing the up or down button. * STEP 11: Additional actions. Process end. If the process has been completed without errors, the parameter TUN.00 will be automatically set to zero by the inverter. Therefore, the inverter would stop to be in autotuning mode and we could proceed to the next point.

131

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter If during the process execution an error occurs, this error will appear and it will leave the inverter in permanent out of service and ABSOLUTELY NO parameter will be modified, even TUN.00 which is set to the value 09999. We must determinate the error cause, solve it and carry out once more this process from the beginning. Errors associated to the autotuning process are related in section 10.3.4. Autotuning errors of the present manual. 12.2.7. Adjustment of speed control and current filter IMPORTANT NOTE: Before proceeding with the adjustment of the speed control and the current filter, we must be 100% sure that the previous autotuning process, if it has been carried out, is successfully completed and without any error. Once we are sure about this, we must carry out the following protocol: 1) Ensure that parameter TR0.03 = 10. 2) Hang the car and the counterweight. It makes no sense to adjust the speed and position controls at this point, as these settings change from being with no load or with load. 3) Check the initial values of the parameters associated to the speed control and the current filter. There are three possible cases: a) The inverter is pre-parameterised. These are cases in which the inverter is part of a complete lift order and the autotuning execution is not indicated as compulsory (TUN.00 = 0). Another possibility is that the inverter has been specifically supplied for this installation, as a result of a claim inquiry. In this case, proceed to following point. b) The inverter is not pre-parameterised. These are cases in which even if the inverter is part of a complete lift order, the autotuning execution is indicated as compulsory. Also in those cases in which the inverter comes from another installation or from the own customer warehouse or from the branch or if it has been supplied from Servicenter or from the factory with a generic parameterisation. In these cases, if we have the profile associated to the machine/installation or the inverter parameterisation of another identical installation/machine that works properly, we will set the parameters according to this document or to this configuration. If the profile associated to the machine does not exist, the default values of these parameters will be used as initial values. These values can be consulted in the parameter table of the synchronous version (section 8.4). c) We do not know whether it is pre-parameterised or not. In this case, contact MP for support or use the default values of these parameters as initial values (section 8.4). 4) Move the car in inspection or rescue mode. If a speed error appears (11, 06 or 14)7 while starting, we must set following parameters to following values: a) POS.01 = 200 (usually, to 250 or 300). b) VEL.00 = 15000 (usually to 20000). If the problem persists, decrease VEL.00 up to 10000, never more than this. 5) If the problem persists, check that INT.09 = 2 and make the test with the following values of PEC.00: 12.0 Khz, 14.0 Khz and 10.0 KHz. What we are doing at this point is to configure the current filter (refer to Figure 12.2), by varying its cut off frequency. This filter aim is eliminate the mechanical resonance frequencies. But we must bear in mind that these frequencies are inherent to the complete lift: machine, guide rails, car, counterweight, pulleys, etc. 7

For versions 612 and higher, unlike previous versions, there are three errors associated to speed:

• Error 06: Motor blocked: The machine is lower than the target speed. • Error 11: Overspeed/runaway: The machine is higher than the target speed. • Error 14: Overspeed in reverse: the machine moves in the opposite direction to the target direction.

V0.01 – 04/2013

132

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter Therefore, even if we know the machine profile, the latter can slightly vary depending on how the assembly has been made. Why is it adjusted by varying INT.09 and PEC.00? On one hand, by setting INT.09, we configure the filter for a PEC.00 of 12.0 KHz. If we increase PEC.00, we are also proportionally increasing the cut off frequency. If we decrease it lower than 12.0 KHz, we are also proportionally decreasing the cut off frequency. 6) If the speed error persists (11, 06 or 14) while starting, we must know if it is caused by a machine vibration or a movement’s wrong direction or an overspeed in reverse (due to a short circuit or any phase disconnection). Therefore, we can cancel the speed error and just let the overspeed error on the rated speed (TR0.03 = 0), then make the test in inspection or rescue mode. Do not forget to restore this parameter to its initial value (10). 7) If in point 6 we determine that it is due to vibrations, decrease VEL.01 and VEL.03 up to 15000 and, if the problem persists, up to 10000, never lower than this. If it is due to a movement’s wrong direction or an overspeed in reverse, check the connection of the machine phases.

12.2.8. Check of the run direction The run direction depends on three factors: 1. Connection of sinusoidal encoder 2. Connection motor phases 3. Location of the machine into the shaft: right or left. In MP inverter/machine sets, the two first factors are fixed at the factory. However, since the inverter can be supplied as a component or as part of a complete lift, this adjustment must be carried out in situ.

IMPORTANT NOTE In this machine type (gearless/synchronous), never change the phases to modify the run direction, like we use to do in induction machines (asynchronous).

To set the proper run direction, the following steps must be carried out: 1. SET THE CONTROL BOARD IN INSPECTION OR MES MODE. 2. PRESS TH UP (OR DOWN) BUTTON. - If it goes downwards (or upwards) respectively, i.e., if it carries out the operation in the opposite direction to commanded one, modify parameter CNF.05: * If CNF.05 = 1, set CNF.05 = 0 * If CNF.05 = 0, set CNF.05 = 1 - Try again to press the up (or down) button.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 12.2.9. Adjustment of S- curves The speed is defined like the position change with respect to the time - first derivative of the position. The acceleration is defined like the speed change with respect to the time - first derivative of the speed or second derivative of the position. The jerk is defined like the acceleration change with respect to the time - first derivative of the acceleration. Our sensitivity is associated to this magnitude, i.e., to the acceleration changes and this is what may cause an unpleasant sensation to the car lift passengers while starting and stopping. Therefore, these are the points (starting and stopping) where we have to assign the speed commands to the motor in such a way as to achieve smooth changes of acceleration. The speed profile we obtained this way is called S-curves. In the following figure, we can see the profiles of speed, acceleration and jerk for a linear curve and an S-curve.

FIGURE 12.5 3VFMAC-DSP 6P supports two types of S-curve: Standard and Sinusoidal. We can select any of them by means of the parameter RSN.00 setting:

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 12.2.9.1. Standard curves Standard S-curves are exactly the same that the ones incorporated in 3VFMAC1. We start from a linear profile of the speed and by means of the constants RSN.01, RSN.02, RSN.03, RSN.04 we smooth the slope changes of the speed.

o o

RSN.01, RSN.02: Acceleration Beginning and End; from speed 0 up to rated speed. RSN.03,RSN.04 : Deceleration Beginning and End; from rated speed up to approach speed

FIGURE 12.6

The higher the number set in parameters RSN.01-RSN.04, the more gentle in the associated zone. IMPORTANT NOTE: When we use this type of curves, the acceleration time TR1.02 and deceleration time TR1.04 are affected by the constants RSN.01-RSN.04. We could say that the values set in TR1.02 and TR1.04 would be the acceleration and deceleration times if parameters RSN.01-RSN.04 have the value 1. At the same time that these parameters are being increased, the times of acceleration and deceleration are being increased too.

FIGURE 12.7 12.2.9.2. Sinusoidal curves These curves are called sinusoidal since the profiles of the acceleration and jerk are sinusoidal. An important difference to bear in mind with respect to standard curves is that this type of curves observes scrupulously the acceleration time (TR1.02) and the deceleration time (TR1.04), using exactly the time indicated by these parameters, neither more nor less. Therefore, if we set too low values in these parameters, it may happen that we get errors like Err 04 (low voltage of capacitors), Err 02 (over current) or Err 13 (unstable voltage of capacitors). To solve this problem, just increase TR1.02 and/or TR1.04. Standard curves are said to be partial S-curves, since we start from a linear acceleration and we modify, by means of constants and one by one, the zones of slope speed. Sinusoidal S-curves are said to be complete S-curves, since the obtained speed curve corresponds to a unique function which depends on the initial speed, final speed and time of acceleration or deceleration. That is, 3VFMAC-DSP 6P determine the complete curve for these parameters.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter There is only one point left to be treated: modification factor for acceleration curve (TR1.03, TR1.05). The modification factor for acceleration curve is nothing less than a "deformer" of the curve in such a way that:

• the higher the value, the softer the beginning of the curve and the harder at the end and vice versa, and

• the lower the value, the less gentle the beginning of the curve and the softer at the end. The value that does not "deform" the curve (neutral value) is 1.00. The most convenient is to smooth the acceleration at low speeds. Therefore, the default value of TR1.03 (modification factor for acceleration curve) is 1.50. 12.2.9.3. Which type of curve to choose? Whenever it is possible, the sinusoidal S-curve (default value): The obtained jerk is lower than the one resulting from standard curves. 12.2.9.4. Adjustment process for standard curves 1. Adjustment of the acceleration curve: TR1.02, RSN.01, RSN.02 The adjustment of the acceleration curve corresponding to the standard curves consists of the adjustment of 3 parameters:

• TR1.02 (acceleration time) • RSN.01 (constant of acceleration beginning) • RSN.02 (constant of acceleration end) These three parameters have to be simultaneously adjusted. Let us remind, as already mentioned in section “12.2.9.1. Standard curves” of this document that the acceleration final time depends on these 3 parameters, because TR1.02 is affected by the constants RSN.01 and RSN.02: the higher these constants, the gentler the beginning and the end of the acceleration and the longer the final time invested. The values set in these parameters will be a compromise between the required comfort during the acceleration curve and the final time invested in the acceleration. The default values for these parameters are TR1.02 = 2.50 s, RSN.01 = 50, RSN.02 = 50. 2. Adjustment of the deceleration curve: TR1.04, RSN.03, RSN.04 The adjustment of the deceleration curve corresponding to the standard curves consists of the adjustment of 3 parameters:

• TR1.04 (deceleration time) • RSN.03 (constant of deceleration beginning) • RSN.04 (constant of deceleration end) These three parameters have to be simultaneously adjusted. Let us remind, as already mentioned in section “12.2.9.2. Standard curves” of this document that the acceleration final time depends on these 3 parameters, because TR1.04 is affected by the constants RSN.03 and RSN.04: the higher these constants, the gentler the beginning and the end of the deceleration and the longer the final time invested. Once the approach speed, is reached, it is important it remains stable for a time between 1 and 2 seconds. To do this, we will use the viewing "FrEC" where the low speed command must be displayed for the indicated time: between 1 and 2 seconds: - If it is displayed for less than one second, we can:

• Or reduce the deceleration time (TR1.04). We have to do this carefully because a too low • • •

value in this parameter can cause Err 02, Err 04 or Err 13. We will do this by decreasing 0.20 seconds at a time. Or slightly reduce RSN.03 without compromising the comfort at the deceleration beginning, by using decreases of 20 units. Or slightly reduce RSN.04 without compromising the comfort at the deceleration end, by using decreases of 20 units at a time. Or increase the approach speed, by increases of 0.5 Hz at a time.

- If it is displayed for more than 2 seconds, we can:

• Or increase RSN.04 • Or increase RSN.03 • Or increase the deceleration time (TR1.04). 12.2.9.5. Adjustment process for sinusoidal curves 1. Adjustment of the acceleration time: TR1.02 As already mentioned in section “12.2.9.2. Sinusoidal curves”, this type of curves scrupulously observes the times of acceleration set in TR1.02. It is not recommended to set too low values in these parameters are, because it may cause errors like Err 02, Err 04 or Err 13. We will configure this acceleration time according to the gentleness that we want to give during the acceleration. The default value is 2.50 s. 2. Adjustment of the modification factor for acceleration: TR1.03 This parameter affects only the profile of the target speed during the acceleration:

• the higher the value, the softer the beginning of the curve and the harder at the end and vice versa, and

• the lower the value, the less gentle the beginning of the curve and the softer at the end. This parameter affects only the speed profile. It does NOT affect the acceleration time: it does not increase or decrease it. Its default value is 1.50. 3. Adjustment of the modification factor for deceleration: TR1.04 The sinusoidal curves scrupulously observe the times set in TR1.04. A too low value may cause errors like Err 02, Err 04 or Err 13. Once the approach speed is reached it is important it remains stable for a time between 1 and 2 seconds. To do this, we will use the viewing "FrEC" where the low speed command must be displayed for the indicated time: between 1 and 2 seconds: - If it is displayed for less than one second, we can:

• • •

Or slightly reduce the deceleration time (TR1.04). We have to do this carefully because a too low value in this parameter may cause Err 02, Err 04 or Err 13. We will do this by decreasing 0.20 seconds at a time. Or increase the approach speed, by increases of 0.5 Hz at a time. Or both.

- If it is displayed for more than 2 seconds, we will increase the deceleration time, by increases of (TR1.04) of 0.20 seconds, until reaching the indicated range.

• the higher the value, the softer the beginning of the curve and the harder at the end and vice versa, and

• the lower the value, the less gentle the beginning of the curve and the softer at the end. When we say that it affects only the speed profile, we mean that it does not affect the deceleration time: it does not increase or decrease it. Its default value is 1.00. 12.2.10. Adjustment of levelling 12.2.10.1. Stopping time (RSN.05) The parameter RSN.05 is the stopping time: i.e., how long it takes to the lift to get from the approach speed to speed 0. Values with milliseconds accuracy can be introduced. The stopping S-curve is ALWAYS sinusoidal type -with modification factor 1.00, independently of the S-curve type selected (RSN.00 = 0 or RSN.00 = 2). The unique parameterisable datum of the stopping curve is the time. It has been designed like this because, as already mentioned in previous section, the sinusoidal curve jerk is much lower than the standard curve one. 12.2.10.2. Levelling adjustment The aim of the levelling adjustment process is not the exact levelling with floor level; the real aim is to achieve a uniform stopping point (always the same) independently of the load, either up or down service. Once this is achieved, the levelling magnets will be moved in order to make the lift stopping point coincide with the floor level. Hereafter, the sequence of the actions to be carried out in order to achieve the levelling adjustment is explained. These actions must be made according to this sequence, because if the order is modified, it will be very difficult to achieve a proper levelling of the lift. The adjustment procedure is different whether the installation is going to operate in open-loop (without encoder) or in closed-loop (with encoder).

1. Readjustment of TR1.01: Optional The aim of the readjustment of TR1.01 is to make a first rough approximation of the distance between the magnetic reader and the magnet, leaving RSN.05 for the fine adjustment. Thus, once adjusted, the value of the stopping time parameter RSN.05 would be neither too high nor too low. In some cases, too high could cause problems in stopping with full load. Too low could cause an abrupt stopping. To carry out this adjustment phase, a person will get on the car roof to take the required measurements. The steps to follow are: a. Choose a destination intermediate floor (D) b. Choose a departure floor A in such a way that: - It is located above the destination floor D - It is not the highest floor - There are at least two levels until the destination floor c. Choose a second departure floor B in such a way that: - It is located bellow the destination floor D - It is not the lowest floor - There are at least two levels until the destination floor D d. Make a travel from the upper departure floor A until D. Measure the distance from the magnet beginning up to the place where the magnetic reader is, as shown in the figure.

Analyse the obtained result for the runs carried out: - In the downwards service (d), if we obtain a stopping point higher than the one obtained after the upwards service (e), increase RSN.05 slightly and gradually, by increases of 0.050 seconds (for example: from 0.800 to 0.850). Once RSN.05 is modified, return to point.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter - In the downwards service (d), if we obtain a stopping point lower than the one obtained after the upwards service (e), decrease RSN.05 slightly and gradually, by decreases of 0,050 seconds (for example: from 0.800 to 0.750). Return to point d after RSN.05 is modified. - If the levelling point coincides in both cases (d, e), proceed to relocate the level magnets. 3. Relocation of level magnets Previous adjustments enable to make the lift stop at the same point, with or without load, and in up direction or in down direction. Then, we just have to make that (already uniform) point coincide with the floor level. To do so, duly move the magnets which determine the levelling point at each floor, and correct the existing deviations at every stopping. NOTE: If there is any case where the modification is higher than 5 cm, the points of deceleration beginning (pulse magnets) will have to be modified in order to keep constant the deceleration section and the approach section to floor. Finally, we must check that the distance between the approach magnet and the stopping magnet is the same at every single level. 12.2.11. Adjustment of short floors 12.2.11.1. What is a short floor? The notion of "short floor" within the inverter context is different from the notion of "short floor" within the control board context. Here, we talk about "short floor" from the inverter point of view when the rated speed is not achieved during a service. It may occur because:

• •

it is a particularly short floor, or during the service between adjacent floors, the rated speed is not achieved either. This is the most common case. It happens in those lifts working at 1.6 m/s or 1.0 m/s, with large acceleration sections.

This circumstance can be appreciated in the value of the viewing "FrEC" which falls short of reaching the rated speed. 12.2.11.2. Adjustment aim When configuring a "short floor", the main aim is that the time elapsing at low speed is not excessive, in such a way that the service would take longer than required. 12.2.11.3. How to adjust a short floor? There are two parameters, both in group RSC (Short S-Ramp), to adjust short floors: RSC.00 and RSC.01.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

When the inverter meets the signal of approach frequency, it makes the following:

• It will go on with the frequency ramp a “little more”, i.e., it will go on increasing the frequency a “little more”. - For standard S-curves, this “little more” is automatically calculated by the inverter according to the acceleration time and the cut off frequency, in the same way its predecessor, el 3VFMAC1, did it. - For sinusoidal S-curves, this “little more” is quantified by parameter RSC.01. By default, it is set to a value of 50. The longer RSC.01, it will go on increasing the frequency for longer and, therefore, the shorter approach time.

• After completion of the frequency ramp, it can keep the frequency reached for a certain time which will be calculated from the RSC.00 parameter value: RSC.00 is the time during which the final frequency of the ramp cut off is going to be kept if the latter was half of the rated frequency. Thus, the higher the frequency at the end of the cut off ramp, the shorter the extension time and vice versa, the lower this frequency, the longer the extension time. Thus, the tendency is always to achieve the set objective: reduce the time at low frequency. The formula is the following one:

TR1.00 x RSC.00  CUT OFF FREQ/SPEED    2   For instance: let us suppose that TR1.00 = 20.00 Hz and RSC.00 = 1.000 s. CUT OFF FRECUENCY 5.00 Hz

2.000 s

10.0 Hz = TR1/2

1.000 s = RSC.00

15.00 Hz

0.667 s

20.00 Hz

0.500 s

Extension Time

TABLE 12.8 Parameter RSC.00 applies for both types of curves (sinusoidal and standard). Nevertheless, when selecting Sinusoidal S-curves (RSN.00 = 2), it is usually set it to zero (RSC.00 = 0.000), because the adjustment of RSC.01 may normally be enough.

TABLE 12.9

To adjust these parameters, the best option would be to make it with the maximum load. However, this case is usually impracticable; therefore, we describe the adjustment made with an empty car. The adjustment of these parameters is carried out in the following way: • In 2:1 installations: the position control mode POS.00 is set to 1 and POS.01 and POS.02 are adjusted with same value. We start with 200 and increase 50 by 50 units until the rollback disappears, both at starting and at stopping. Then, we stop. The tests will be done at departure and arrival at the top level (with empty car). Once the value is determined, we will make the test at the intermediate level and at the lowest one. If the machine makes oscillations or rumble, decrease the value of 50 by 50 units, until this effect disappears. In this type of installations, the values are usually included in a range between 200 and 400. • In 1:1 installations: the position control mode POS.00 00 is set to 2 and POS.01 and POS.02 are adjusted in an independent way. Installations with a 1:1 suspension are more likely to a stroke on the starting; it is more a feeling than an actual vibration, like a fast elastic movement, before the beginning of the travel. To avoid this behaviour, the position control mode POS.00 is set to 2. POS.01 and POS.02 are adjusted in the following way: POS.01 Position control at starting. We start with from the initial value of 500. We will make the test from the highest floor and increase 50 by 50 units in order to reduce as much as possible the starting jerk when the brake opens. Here, we have to be careful in order to distinguish whether it happens when the brake opens or when the movement begins. It is the first case we are mentioning in this point. Once the value is determined, we will make the test at the intermediate level and at the lowest one. If the machine makes oscillations or rumble, decrease the value of 50 by 50 units. POS.02 Position control at stopping. We start with 200 and increase 50 by 50 units until the rollback appears when stopping at the highest floor. Once the value is determined, we will make the test at the intermediate level and at the lowest one. If the machine makes oscillations or rumble, decrease the value of 50 by 50 units.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 12.2.13. Adjustments of brake The 3VFMAC-DSP 6P inverter is basically provided with 4 parameters for the adjustment of the activation/deactivation of the machine brake. These parameters are related in following table:

PARAM STC.08

DESCRIPTION It determines the role of pin 19 in XC2 connector.

STC.00

Delay between brake activation command and start of motor spinning. I.e., time between brake relay activation and brake opening. Time elapsed between brake deactivation and motor power failure at stopping. I.e., time between brake relay activation and brake closing. It determines the time current drop once the brake has been activated.

STC.02

STC.09

RANGE 0: Reset/Error 1: N/Open Brake microswitches reading/activated 2: N/Closed Brake microswitches reading/deactivated 00.01..02.50 s

00.01..02.50 s

0.00..3.00

TABLE 12.10 Synchronous machines (gearless) are usually provided with two brakes coupled to the motor’s rotor where also the machine pulley is directly coupled. Each brake includes a microswitch to enable its state monitoring. To optimize the starting and stopping times, the reading of brake microswitches must be enabled. If you want to comply with A3 Amendment of EN81 or, only meet safety recommendations, just wire the normally closed contacts in series and connect them to terminals 5, 6 of connector XMAQ (schemas 12.1, 12.2). These contacts go straight to the input XC2/19 of the inverter. To enable the reading of the normally closed brake microswitches, we must set parameter STC.08 to 2 (refer to table 12.10) and/or enable the A3 Amendment function (A3A.00 = 1). When connecting the brake microswitches, the inverter console displays “rESEt” blinking, it means that the input XC2/19 is configured with error reset.

12.2.13.1. Opening and closing times. Reading of the machine brake microswitches Reading of brake microswitches deactivated (Not recommended. Not in compliance with A3/EN-81 Amendment): STC.08 = 0. When starting, the inverter’s brake relay KRL3 will be activated. After STC.00 seconds are elapsed, the movement will start. When stopping, the inverter’s brake relay KRL3 will be deactivated. After STC.02 seconds are elapsed, the motor power failure will start. The opening and closing times of the brakes depend on the temperature and the input voltage and they can be different each other. If the values of parameters STC.00 and STC.02 are too tight, when the installation conditions (voltage and temperature) change, the inverter may issue errors 18 and 19. If we adjust them taking into account the worst conditions, we will be penalising the starting and stopping times. This is the reason why it is not recommended. The opening (STC.00) and closing (STC.02) times are adjusted in the same way but independently. We will start from value 1.20 s. • If no error appears, decrease by 0.20 s at a time until error 18 or 19 appears. The resulting value must be increased in 0.50 s. • • If error 18 or 19 appears, increase the value by 0.20 s at a time until error disappears. The resulting value must be increased in 0.50 s.

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter

VERY IMPORTANT THIS CONFIGURATION IS NOT IN COMPLIANCE WITH A3 AMENDEMENT OF STANDARD EN81.

Reading of brake microswitches activated: STC.08 = 1, 2 or A3A.00 = 1 (Recommended) When starting, the inverter’s brake relay KRL3 will be activated. The moment it is determined by the reading of brake microswitches that the machine brake is mechanically opened the movement will start. After STC.00 seconds are elapsed if the brake remains closed, error 19 will occur. When stopping, the inverter’s brake relay KRL3 will be deactivated. The moment it is determined by the reading of brake microswitches that the machine brake is mechanically closed, the motor power failure will start. After STC.02 seconds are elapsed if the brake remains opened, error 18 will occur. Therefore, as a general rule, the values of STC.00 and STC.02 must be set to 2.00 s, since the inverter will detect by the reading of brake microswitches at what moment it opened or closed. If there is any problem with the brake and the latter does not open (or close) after two seconds and half, an error of reading of brake microswitches (18, 19) occurs. If any kind of error occurs in the inverter during the stopping, the latter would be abruptly carried out. A classic case could be that the control board opens the contactors due to an opening in the safety chain. Then, the inverter would issue error 0E. In principle, it would not be a matter of stopping adjustment; so we must analyse the error cause and correct it. If we activate the A3 Amendment (A3A.00 = 1, 2) function, we will be activating reading of normally closed brake microswitches, independently of the value of STC.08.

12.2.13.2. Motor power failure After the machine brake is mechanically closed, the motor power failure starts. If the motor power is abruptly cut off, a “klonk” would be heard and a little jerk would be felt in the car (since the car would not move). Do not confuse this “klonk” and the little jerk sensation with an oscillation and an actual movement of an abrupt stopping caused by an error occurrence (refer to previous section). This “klonk” is due to the small clearance in the machine brake. At stopping, if the machine power is abruptly cut off, the load will cause an abrupt movement in the favourable direction. This effect is neither critical nor problematic, since the brake is already closed. However, this unpleasant sensation can be removed by means of parameter STC.09, whose value is the time, stated in seconds, of the current drop ramp. The default value of this parameter is 1.00 s. To adjust these parameters, the best option would be to make it at the lowest floor with the maximum load. However, this case is usually impracticable; therefore, we describe the adjustment made with an empty car and at the arrival to the highest floor. In short, with the value of parameter STC.09 set to 1.00 s, we distinguish two initial cases: 1.

If the “klonk” is not heard: in this case, it is a matter of decreasing this value until the “klonk” is heard. The resulting value must be increased in 0.20 s.

2.

If the “klonk” is heard: in this case, it is a matter of decreasing this value until the “klonk” is heard. The resulting value must be increased in 0.20 s.

13. OTHER SPECIAL FUNCTIONS 13.1. Adjustment of sensors 13.1.1. General The adjustment process of current sensors applies both to synchronous and asynchronous motors. This process’ aim is the adjustment of the amplitude of the current V phase in respect to the one of U phase, carried out at the rated current point of output to motor, in such a way the error is lower than 1%. In asynchronous inverters, the output rated current is determined by the inverter type in terms of power/voltage. Refer to table of specifications in section 16 of the present document. In synchronous inverters, the output rated current is determined by parameter DRI.07, whose maximum value corresponds to the rated current of the device in terms of power/voltage. Unlike the autotuning process, the no-load machine is NOT required; so no need to remove the traction cables of car and counterweight from the machine pulley. 13.1.2. Process execution The process execution of the adjustment of sensors is carried out through parameter TUN.01. To modify/execute this parameter, there is no need to enter SETUP with advanced access code. To command the process execution of the adjustment of sensors, set the parameter TUN.01 to value 00001. To complete the process and as a result of it, if no error occurred during the course, the adjustment of the V phase current as well as the values of a group of parameters will be set and, in addition, the parameter TUN.01 itself will be set to zero. If any error occurs and/or the process is interrupted in any way, NO parameter will be modified. We must remind, as already mentioned in previous section, that the process execution of the adjustment of sensors does NOT require no-load machine, since it will not even open the brake. The process of the adjustment of sensors consists of following steps: * STEP 1: Set the control board in inspection or MES mode. * STEP 2: Activate the adjustment of sensors: TUN.01 = 00001. * STEP 3: Exit the SETUP mode. * STEP 4: The console will display, blinking and alternately:

* STEP 5: Keep on pressing the up or down button of the rescue command or of the inspection box. Along the process the display will show, blinking:

A d J X X where XX represents the adjustment number which is being carried out at every moment. The process will take between 30 and 45 seconds, during which the machine must remain motionless and the brake deactivated.

If any error occurred during the process, the information related to it will be displayed in the console; the inverter will be out of service. In this case, the value of TUN.01 will go on being 00001. 13.1.3. Errors of adjustment of sensors If any error occurred during the process, NONE of the changes in current adjustments would be effective, the corresponding error would be displayed and the inverter state would be permanent out of service. The errors associated to the process of adjustment of sensors are related in following table: CODE

TABLE 13.2.2 13.2. Test Mode (asynchronous motors only) 13.2.1. General Test mode is a special operation mode in which the inverter informs, via console, about the state of current sensors and encoder. This procedure does not generate errors, it just informs about them when existing. The test mode activation is carried out through parameter TST.00. When this parameter is set to value 1, we are activating the test mode. When it set to value 0, the test mode is deactivated.

Then, the "Encod" viewing value would be 0 in any situation. Once the required checks are made, check again the encoder from the beginning. • STEP 6: Deactivate the test mode: TST.00 = 0. If required, in addition, set back to closed-loop operation mode (CNF.00 = 1).

13.3. 3VF Rescue Modes 13.3.1. General 3VF RESCUE Modes are special operation modes. They are activated in the event that power supply is interrupted and automatically carried out by the main board and 3VFMAC-DSP 6P. In the event of power supply outage, this process’ aim is to take the car to floor level and open the doors. Then, the process is completed. At the present moment, 3 3VF rescue modes are coexisting: • DSP RESCUE 5 BATTERIES • DSP RESCUE 4 BATTERIES • DSP-UPS RESCUE (without batteries) Currently manufactured controllers provided with rescue system are supplied with DSP rescue-4 batteries or DPS-UPS rescue (without batteries). DSP rescue-5 batteries was the first type of DSP rescue launched on the market and, therefore, 3VFMAC-DSP 6P inverters maintains full compatibility, both on software and hardware. The implementation of 3VF Rescue Modes is carried out by a set consisting of the following elements: UPS, switching contactors (if existing), batteries (if existing), wiring, inverter software and control board software. We refer to this element group as rescue system. Therefore, the control board and 3VFMAC-DSP 6P itself must be specifically prepared for the execution of this special operation mode. The required elements are different according to the involved rescue mode, as detailed in following table.

The DSP rescue with 4 batteries is applied as standard to asynchronous machines. The DSP-UPS rescue without batteries is applied as standard to synchronous machines. In the two modes of DSP rescue with batteries (4 or 5), the latter will supply energy to the traction machine and the UPS will supply the main board, the inverter, the machine brake and the door operator. The 3VF rescue is an automatic rescue mode (disregarded) which is activated in the event of power supply outage. In synchronous motors, do not mix up this rescue mode with the rescue system by means of unbalanced load. The rescue system by means of unbalanced load only applies to synchronous motors. It is carried out by the RESMON board and it is provided with a UPS unit for the supply of the brake and the door operator. In synchronous motors, both rescue modes may coexist. 13.3.2. DSP Rescue-5 batteries To check that a 3VFMAC-DSP 6P inverter is ready for an automatic rescue with 5 batteries, a series of checks must be done at wiring and parameterisation. For the execution of automatic rescue-5 batteries with asynchronous machines, the machine must necessarily be provided with an industrial encoder. Concerning asynchronous machines, remind that they cannot be controlled without an absolute/sinusoidal encoder and the rescue operation is not an exception to this rule. V0.01 – 04/2013

13.3.2.4. Process description In this rescue mode (DSP-5 batteries), there are two switching contactors: KG and KUPS. In normal mode, KG is closed KUPS is open. In rescue mode, KG is open and KUPS is closed. These contactors can NEVER be closed at the same time. Therefore, they are mechanically interlocked. The sequence would be the following one: 1. Cut off the electrical flow. 2. KG opens and KUPS closes, shifting into rescue mode. At transition, the reset of the control board and the inverter may occur. 3. After about 30 seconds, the rescue travel begins. 4. When reaching the floor level, the control board opens contactors K1 and K2 and the inverter displays error 0E. 5. The control board opens the doors and, after a certain time (control board parameter “Time for Next Service”), it deactivates KUPS. 6. At this moment, if the power supply has been restored, KG closes and we shift to normal mode. Otherwise, the control board would switch off until the electrical flow is restored. During the rescue execution, if the power supply is restored, KG remains open and KUPS remains closed, and the rescue operation is carried out. After the rescue travel completion and when the time specified by the control board is elapsed, the latter deactivates KUPS contactor and closes KG contactor. The batteries, whose charge is controlled by the CARBAT board, provide energy to the machine ONLY; the UPS supplies power to all the other elements involved in rescue operation: control board, inverter, machine brake, door operator, etc. In regard with the inverter, the following scheme describes the rescue process, taking as a reference the information provided by 3VFMAC-DSP 6P inverter on the console.

13.3.3.3. Process description In this rescue mode (DSP-4 batteries), there is only one switching contactor: KPW. In normal mode, KPW is closed. In rescue mode, KPW is open. This contactor controls the RST inverter’s input. The sequence would be the following one: 1. Cut off the electrical flow. 2. KPW opens, shifting into rescue mode. In this rescue mode, neither the main board nor the inverter is reset. 3. After about 6 seconds, the rescue begins. 4. When reaching the floor level, the control board opens contactors K1 and K2 and the inverter displays error 0E. 5. The control board opens the doors. 6. After a certain time, about 1 minute, the control board leaves the rescue mode and shifts into normal mode. At this moment, two things may happen: - If there is still no electrical flow, the UPS will switch off and, therefore, the whole controller. - If the electrical flow has been restored, KPW will be reactivated, and the control board will be available to carry out services in normal mode. During the rescue execution, if the power supply is restored, KPW remains open, and the rescue operation is carried out. After the rescue travel completion and 1 minute (point 6) is elapsed, the contactor KPW is reactivated and the rescue mode is exited. The batteries, whose charge is controlled by the CHARGER 48V unit, provide energy to the machine ONLY. The UPS supplies power to all the other elements involved in rescue operation: control board, inverter, machine brake, door operator, etc. In regard with the inverter, the following scheme describes the rescue process, taking as a reference the information provided by 3VFMAC-DSP 6P inverter on the console.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 13.3.4.3. Process Description As already mentioned in parameter table of previous section, there are 2 parameters associated to the speed during the rescue and 2 parameters associated to the acceleration time in rescue. When the inverter shifts in rescue mode WITHOUT BATTERIES, the starting process that is launched consists of two straight lines or acceleration ramps: •

Starting ramp: This first ramp is defined by parameters RES.04 and RES.05. This ramp is equivalent to the starting ramp in normal mode determined by the parameters of ARR group. Its function is to overcome the starting friction.

•

Acceleration ramp: Determined by parameters RES.01 and RES.03. Its function is to move the car at the required speed in rescue mode.

FIGURE 13.3 At no time is there any mention of curves and, much less, of S curve, but of ramps and straight lines. The rescue operation aim is to take the car to the floor level and open doors. To achieve this aim, the inverter attempts to save the maximum possible energy and the comfort becomes secondary. However, as a general rule, the rescue speed (RES.01) is set at around 12-15 % of the rated speed and the time (RES.03) between 4 and 6 seconds. The final speed of the initial ramp (RES.04) is set at around 10% of the rated speed and the time (RES.05) at about 1-2 seconds. Parameter RES.06 (rated current during the rescue) will be used by the inverter to set the maximum current limit of output to motor during the rescue operation at two times its value. Its value depends neither on the machine nor on the inverter, but on the only power source during the rescue operation: the UPS. Its usual value is 1.5 Amp, which limits the maximum current to the motor at 3 Amp. It is recommended not to modify this parameter. During the DSP-UPS rescue operation, the inverter tries to move the machine according to the speed targets determined by the parameters of initial ramp and rescue ramp in the most favourable direction in terms of energy. Due to the position into the shaft and/or the load inside the car, it may happen that the lift is that unbalanced that the inverter is not able to move the machine according to the target speed with only the power supplied by the UPS, so that the lift real speed exceeds the target speed. Then, and only then, the inverter will operate like the RESMON command: it will short the motor phases. Let us suppose that at this moment one of the motor phases is accidentally disconnected. The circuit would open and the lift would accelerate. When the speed exceeds the value set in parameter RES.07, the error 11 (overspeed) would appear. The parameter RES.07 value is included in all the machines’ profiles. Usually, it is set at 50% de of the rated speed. In this rescue mode (DSP-UPS) THERE ARE NO SWITCHING CONTACTORS. That means less wiring and less EMC noises. The sequence would the following one: 1. Cut off the electrical flow. 2. Shift into rescue mode. In this rescue mode, neither the control board nor the inverter is reset.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 13.4. A3 Amendment A3 Amendment is a modification dated 2009 to the standard EN81-1, dated 1998, and reflected within the section 9.11. The A3 Amendment’s aim is the protection against unintended movement of the car when doors are open, as reflected in the first section: 9.11.1 Lifts shall be provided with a means to stop unintended car movement away from the landing with the landing door not in the locked position and the car door not in the closed position, as a result of failure in any single component of the lift machine or drive control system upon which the safe movement of the car depends, except failure of the suspension ropes or chains and the traction sheave or drum or sprockets of the machine. In addition, the standard states how and with which elements this movement detection has to be carried out, on which elements we shall act or not, which would be the actions in front of this type of failure, the maximum limits allowed, etc. For the integral text of the standard, refer to appendix C. The A3 Amendment implementation is different depending on the machine type of the installation: with gear (geared, asynchronous) or without gear (gearless, synchronous). The reason of this difference is reflected in sections 9.11.3 and 9.11.4 of the standard: 9.11.3 The means shall be capable of performing as required without assistance from any lift component that, during normal operation, controls the speed or retardation, stops the car or keeps it stopped, unless there is built-in redundancy and correct operation is self-monitored. NOTE Machine brake according 12.4.2 is considered to have built-in redundancy. In the case of using the machine brake, self-monitoring could include verification of correct lifting or dropping of the mechanism or verification of braking force. If a failure is detected, next normal start of the lift shall be prevented. Self-monitoring is subject to type examination. 9.11.4

The stopping element of the means shall act:

a) on the car, or b) on the counterweight, or c) on the rope system (suspension or compensating), or d) on the traction sheave (e.g. on the sheave directly or on the same shaft in the immediate vicinity of the sheave). The stopping element of the means or the means keeping the car stopped may be common with those used for: - preventing overspeed in down direction, - preventing ascending car overspeed (9.10). The stopping elements of the means may be different for the down direction and for the up direction.

In the case of SYNCHRONOUS (without gear) machines, the brakes act on the traction pulley itself. In addition, there are 2 brakes, so that the system is redundant and we can know their state through the reading of brake microswitches. Therefore, we can use them to avoid unintended movement of the car. The case of ASYNCHRONOUS (with gear) is different. The brake acts on the machine rotor (motor shaft), but not on the traction pulley itself, so that this element cannot be used as stopping element. However, the standard does allow that “…The stopping element of the means or the means keeping the car stopped may be common with those used for preventing overspeed in down or up direction”. This is the reason why, an interlocking device has been enabled on the overspeed governor. This device will be controlled by 3VFMAC-DSP 6P. Whatever the case, the inverter’s role, in regard with A3 Amendment, is the control of the stopping element.

13.4.1. A3 Amendment for asynchronous motors (ASYNC) As already mentioned in previous section, in installations including asynchronous motors, the A3 Amendment function has been implemented by using an interlocking device of the overspeed governor. This device consists of an electromechanical coil activated by the inverter via the KRL1 output. In addition, this device is provided with microcontact used by the inverter for its state monitoring via the 19 input of connector XC2. - When the inverter is in idle state, the coil keeps the overspeed governor interlocked. This way, if a car unintended movement occurs, the overspeed governor will act to leave the lift interlocked. - When the inverter is moving the machine, the coil releases the overspeed governor. This way, the overspeed governor operates normally and acts in the event of overspeed. The states of the KRL1 relay output and the XC2/19 input can be monitored through LEDs SP and 19, respectively. The following table shows the two valid states, depending on whether the lift is stopped or running. LIFT STATE

TABLE 13.9 Any discrepancy between the state of the KRL1 output and the state of the XC2/19 input will incur in a specific error associated to the A3 Amendment. These errors will be shown later in section 15.5.1.2. The A3 Amendment function for ASYNCHRONOUS motors is available from version 911A on. 13.4.1.1. Parameters The parameters associated to the A3 Amendment function are gathered in the group of parameters A3A. Their description, range and default values are reflected in the following table: ID

Parameter A3A.00 determines the activation (A3A.00 = 1 or 2) or deactivation (A3A.00 = 0) of this function in the inverter. This parameter has been included to enable the use of inverters with software version 911A or higher in installations WITHOUT A3 Amendment. If the A3 Amendment is deactivated, the KRL1 function will speed limit relay and the function of the XC2/19 input will be RESET OF ERROR. If the A3 Amendment is activated, both functions, speed limit and RESET OF ERROR for KRL1 and XC2/19, respectively, will be cancelled and they will take the required functions for the A3 Amendment function, such as interlocking device control and reading of its state. There are two modes for this function activation: - A3A.00 = 1: A3 Amendment activated with “automatic reset”: Any other error associated to the A3 Amendment will be automatically reset by the inverter, with no need of the maintenance staff intervention.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter - A3A.00 = 2: A3 Amendment activated with “manual reset”: Any other error associated to the A3 Amendment will leave the inverter out of service. To reset this error, the maintenance staff intervention is required and one of the following actions has to be carried out: a) Enter SETUP and then exit. b) Press the red button P/R of the console. c) Switch off and on again the device. The default value is 1 (function activated with automatic reset) as there are arguments against any one of the other two options: - IT IS NOT 2 because, according to certification bodies, the option of automatic reset (value 1) complies with the standard. Thus, the inverter will never be out of service because of occasional errors associated to A3 Amendment appeared. But, if the certification bodies would change the criteria relating to this point in such a way that the manual reset becomes compulsory, with just changing the value of one parameter it would be enough. - IT IS NOT 0 to avoid a possible interlocking of the lift. If the function associated to A3 Amendment is implemented in the installation, but it is not enabled in the inverter (A3A.00=0), the moment the lift starts moving, the interlocking will occur. If the function associated to A3 Amendment is NOT implemented in the installation, but it is enabled in the inverter (A3A.00=1), in idle state, error 30 (associated to A3 Amendment) will appear. All we have to do is to deactivate the function (A3A.00=0).

VERY IMPORTANT IF THE FUNCTION ASSOCIATED TO A3 AMENDMENT IS IMPLEMENTED IN THE INSTALLATION, BUT IT IS DISABLED IN THE INVERTER (A3A.00 = 0), THE LIFT INTERLOCKING WILL OCCUR. * A3A.01: Time of interlocking Parameter A3A.01 or time of interlocking is the time elapsing between the contactors’ opening (out of the stopping cycle) and the re-interlocking of the overspeed governor. “Contactors’ opening of contactors out of the stopping cycle” means any contactors’ opening due to the appearance of an error in the inverter or due to the detection of an opening in the safety chain. By instance, the lift stopping in MES mode or INSPECTION mode is carried out when the control board opens the safety chain, which incurs in error 0E in the inverter. A further example would be when, in normal operation mode, a low voltage error (err 04) occurs during a travel. In both cases, when detecting the error, the inverter deactivates its outputs of contactors (KRL2) and brake (KRL3) and it stops supplying energy. With ASYNCHRONOUS (GEARED) machines, the moment the lift starts braking (brake coils deactivated), there is a small slipping of the rotor on the brake shoes. This slipping magnitude depends on a large number of factors, like the shoe state, the brake power supply and its adjustment, el the counterweight balance, etc. Therefore, the slipping time can vary from an installation to another one. If the overspeed governor is interlocked while moving, the lift's interlocking would occur. This is the reason why there is a time delay between the contactors’ opening and the re-interlocking of the overspeed governor. If the stopping is carried out according to the normal stopping cycle and without errors, meaning that the brake closes with rotor stopped, this time delay does not happen. * A3A.02: Time of release. This is the waiting time between KRL1 activation (overspeed governor released) and the reading via XC2/19 input that the overspeed governor is released.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 13.4.1.2. Errors In the asynchronous version 911A, there are two errors associated to A3 Amendment and both are the result of any discrepancy between KRL1 output state and XC2/19 input state (refer to table 13.4). Error 30: Error of overspeed governor interlocking. The interlocking device of the overspeed governor should be interlocking the governor, but the inverter understands it is not. Check that KRL1 output is deactivated and XC2/19 input is activated. Check that the governor is provided with the interlocking coil. If yes, check its power supply. Error 31: Error of overspeed governor released. The overspeed governor coil should be releasing the governor, but the inverter understands it is interlocked. Check that KRL1 output is activated and XC2/19 input is deactivated. If there is not any problem with the output or with the input, the lift has probably been interlocked. The behaviour of these errors is determined by parameter A3A.00 value, as already mentioned in previous section: A3A.00 = 1: Automatic reset. Both errors (30 and 31) are “infinite” or “uncountable”. The appearance of any of them will NEVER leave the inverter in permanent out of service. A3A.00 = 2: Manual reset. The appearance of any of them (30 or 31) will leave the inverter in permanent out of service and will require a human intervention for reactivation. 13.4.2. A3 Amendment for synchronous motors (SYNC) In installations provided with synchronous (without gear) machines, A3 Amendment implementation uses, like stopping element, the two machine brakes that are acting directly on the traction pulley. The main board takes part as a further element of the A3 Amendment implementation. Therefore, the board must know, at all time, the inverter state. For this purpose, the KRL1 inverter output to one of the main board inputs has been enabled, in such a way that if: • KRL1 Activated: The inverter is available to carry out a service. • KRL1 Deactivated: The inverter is NOT available to carry out a service. It may suffer an error, it may be in programming mode or it may be switched off. Thus, the main board remains informed at all time about the inverter state. A3 Amendment function for SYNCHRONOUS motors is available from version 613 on. 13.4.2.1. Parameters The parameters associated to the A3 Amendment function are gathered in the group of parameters A3A. Their description, range and default values are reflected in the following table: ID

NAME

A3A.00 A3 Amendment Activation

A3A.01 Time of sampling

DESCRIPTION

RANGE

0: Deactivated This parameter specifies whether 1: Activated, the function associated to A3 automatic reset amendment is activated. 2: Activated, manual reset This parameter specifies the time during which the brake microswitch signal will be analysed.

DEFAULT VALUES

1

This parameter will only be effective if A3A.00 has a value different from zero (1 or 2). TABLE 13.11

MTELCVFDSP6P_001_EN

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter * A3A.00: A3 Amendment Activation Parameter A3A.00 determines activation (A3A.00=1 or 2) or not (A3A.00=0) of this function in the inverter. This parameter has been included to enable the use of inverters with software version 613 or higher in installations WITHOUT A3 Amendment. If A3 Amendment is deactivated (A3A.00=0), the KRL1 function will be the limit speed one and the function of the XC2/19 input will be defined by the value of STC.08. If this parameter value is different from zero (A3A.00 = 1 or 2), i.e., if A3 Amendment function is activated, with or without automatic reset, then: 1) The KRL1 function as a limit speed relay is cancelled, leaving without effect some of the TR0.01 (speed limit) parameters and TR0.02 (speed limit logic) parameters. 2) Independently of the value set in parameter STC.08, the XC2/19 input is set out as reading of normally closed brake microswitches.

VERY IMPORTANT FOR THE A3 AMENDMENT IMPLEMENTATION, IT IS COMPULSORY THAT THE NORMALLY CLOSED TERMINALS OF THE BRAKE MICROSWOTCHES ARE WIRED IN SERIES.

There are two modes for this function activation: - A3A.00 = 1: A3 Amendment activated with “automatic reset”: Any error associated to A3 Amendment will be automatically reset by the inverter, with no need of an intervention from the maintenance staff. - A3A.00 = 2: A3 Amendment activated with “manual reset”: Any error associated to A3 Amendment will leave the inverter out of service. To Reset this error and intervention from the maintenance staff is required and one of the following actions must be carried out: a) Enter SETUP and, then exit. b) Press the red button P/R of the console. c) Switch off and on again the device. The default value is 1 (function activated with automatic reset) as there as there are arguments against any one of the other two options: - IT IS NOT 2 because, according to certification bodies, the option of automatic reset (value 1) complies with the standard. Thus, the inverter will never be out of service because of occasional errors associated to A3 Amendment appeared. But, if the certification bodies would change the criteria relating to this point in such a way that the manual reset becomes compulsory, with just changing the value of one parameter it would be enough. - IT IS NOT 0 to avoid a possible interlocking of the lift. If the A3 Amendment function is enabled in the main board, but disabled in the inverter (A3A.00 = 0), the KRL1 relay will not close, and the main board will understand that the inverter is not available. If the A3 Amendment function is enabled in the inverter and not in the main board, the KRL1 relay will be closed or open, depending on the inverter state, but as this input is not connected to the main board, its state would be irrelevant. * A3A.01: Sampling time Parameter A3A.01 is the time during which the brake microswitch signal will be analysed. Its functioning is similar to a filter's one, because it specifies the sampling time required to validate the reading of brake microswitches. In addition, during this time, an analyse of the signal is carried out that enables noise detection at this input.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 13.4.2.2. Errors There are two errors associated to A3 Amendment in the synchronous version 613: Error 30: The machine brake should be closed, but the inverter reads as if it was open. Error 32: Noise in reading of brake state. During A3A.01 seconds, the inverter analyses and determines both the state and the signal quality of the brake microswitches. The behaviour of these errors is determined by parameter A3A.00 value, as already mentioned in previous section: A3A.00 = 1: Automatic reset. Both errors (30 and 32) are “infinite” or “uncountable”. The appearance of any of them will NEVER leave the inverter in permanent out of service. A3A.00 = 2: Manual reset.

TABLE 15.4 The previous table applies to installations of average traffic (ED9 = 40%) and when the environment temperature (Ta) is lower than 45ºC, with a switching frequency (fc) of 10 KHz. In any other type of conditions, consult MP. For any type of installation not reflected in the previous table, we must size the inverter in such a way that the current and the power are higher than the ones of the selected machine. This increase will depend on the ED, the performance, the switching frequency and the environment temperature of the installation. Should you have any doubt, contact MP for support.

APPENDIX C: EXTRACT OF EN81-1+A3 AMENDMENT

9.11 Protection against unintended car movement 9.11.1 Lifts shall be provided with means to stop unintended car movement away from the landing with the landing door not in the locked position and the car door not in the closed position, as a result of a failure in any single component of the lift machine or dive control system upon which the safe movement of the car depends, except failure of the suspension ropes or chains and the traction shave or drum or sprockets of the machine. NOTE

A failure of the traction sheave includes a loss of traction.

9.11.2 The means shall detect unintended movement of the car, shall cause the car to stop, and keep it stopped. 9.11.3 The means shall be capable of performing as required without assistance from any lift component that, during normal operation, controls the speed or retardation, stops the car or keeps it stopped, unless there is built-in redundancy and correct operation is self-monitored. NOTE

Machine brake according 12.4.2 is considered to have built-in redundancy.

In the case of using the machine brake, self-monitoring could include verification of correct lifting or dropping of the mechanism or verification of braking force. If a failure is detected, next normal start of the lift shall be prevented. Self-monitoring is subject to type examination. 9.11.4 The stopping element of the means shall act: a) on the car, or b) on the counterweight, or c) on the rope system (suspension or compensating), or d) on the traction sheave (e.g. on the sheave directly or on the same shaft in the immediate vicinity of the sheave). The stopping element of the means, or the means keeping the car stopped may be common with those used for: −

preventing overspeed in down direction,

−

preventing ascending car overspeed (9.10).

The stopping elements of the means may be different for the down direction and for the up direction.

TECHNICAL MANUAL OF THE PRODUCT 3VFMAC-DSP 6P Frequency inverter 9.11.5. The means shall stop the car in a distance: −

not exceeding 1,20 m from the landing where the unintended car movement has been detected, and

−

the vertical distance between the landing sill and the lowest part of the car apron shall not exceed 200 mm, and

− the free distance from car sill to landing door lintel, or from landing sill to car door lintel shall not be less than 1,00 m (see Figure 4). These values shall be obtained with any load in the car, up to 100 % of rated load.

Figure 4 − Unintended car movement 9.11.6 During the stopping phase, the stopping element of the means shall not allow a retardation of the car in excess of: −

1 gn for unintended movements in up direction,

−

the values accepted for safety gears in down direction.

These values shall be obtained with any load in the car, up to 100 % of rated load, moving away from a standstill position at landing level.

9.11.7 The unintended movement of the car shall be detected by at least one switching device at latest when the car leaves the unlocking zone (7.7.1). This switching device shall: −

either be a safety contact in conformity with 14.1.2.2, or

−

be connected in such a way as to satisfy the requirements for safety circuits in 14.1.2.3, or

−

satisfy requirements of 14.1.2.6.

9.11.8 NOTE

The means shall operate an electric safety device in conformity with 14.1.2 if it is engaged. This can be common to switching device of 9.11.7.

9.11.9 When the means has been activated or the self-monitoring has indicated a failure of the stopping element of the means, its release or the reset of the lift shall require the intervention of a competent person. 9.11.10

The release of the means shall not require the access to the car or the counterweight.

9.11.11

After its release, the means shall be in a condition to operate.

9.11.12 If the means requires external energy to operate, the absence of energy shall cause the lift to stop and keep it stopped. This does not apply for guided compressed springs. 9.11.13 The unintended car movement with open doors protection means is regarded as a safety component and shall be verified according to the requirements in F.8.
