THE V3F-20 DRIVE The main function of the V3F-20 drive is to adjust the motor speed by means of a change in frequency and voltage. The V3F-20 drive converts the three-phase current (AC) into direct-current voltage (DC) by means of an intermediate circuit made up of filters and capacitors. Direct-current voltage is converted again into three-phase alternating current by means of an intermediate circuit, thereby changing both voltage and frequency. V3F-20 is the first KONE drive system with a completely digital control system, which means an easier installation on the lift. As for V3F-20 technical specifications, see the product specification SOE-11.65.3. On the drive front panel there is an user interface board, which can show the various learning phases and the drive operating status. Fault finding is possible thanks to the LEDs positioned both on the interface board and on the board inside V3F-20.

CONTROL PANEL MOUNTING The EPB 2.4 control panel with the V3F-20 drive must be mounted according to the layout drawing of the machine room. The installation procedure with the V3F-20 drive does not modify the EPB 2.4 control panel one. The control panel complete with EPB 2.4 and V3F-20 is pre-tested and set in the factory according to the lifts characteristics. The control panel must be mounted on the floor with at least 100 mm clearance from the wall to permit the ventilation of the drive. The ventilation system is positioned on the back side of the drive. The V3F-20 system requires the grounding of both the motor power cable (both on the control panel side and on the motor side); cable for tachometer is grounded one end only.

Health and safety at work

–

After switching off the power, wait at least 5 minutes before working or taking any measurements inside the V3F-20 panel and in the motor connection box. As long as the led DANGER is lit on the drive, there are high voltage in the V3F-20 panel (look at the picture on page 6 “V3F-20 open view”).

–

Do not remove the V3F-20 front panel when the drive is supplied.

–

All grounding connections must be carried out properly.

–

Do not carry out flash tests on V3F-20 because the inside electronic circuits are sensitive to high voltage.

–

Do not connect or disconnect any wires while V3F-20 has power supplied to it.

–

Do not touch the braking resistor since there is high voltage on it.

Set-up drive This set-up drive allows V3F-20 to learn the positions of all the floor levels and shaft devices. This is necessary before running on nominal speed. The elevator can normally work only when this set-up drive has been carried out. –

Turn the main switch off.

–

Switch on the inspection drive mode by means of the maintenance control station (42).

–

Disable the car and landing door opening by means of the jumpers (X2 and X5) on the EPB 2.4 board.

–

Turn the main switch on (286:1-2-3).

–

Run the elevator on inspection drive mode to the bottom floor. The leds U61 (61:U), N61 (61:N), 30, UN132 and N136 (136:N) must be on while the led U136 (136:U) must be off.

Make sure that the EPB 2.4 board does not generate error signals; in this case, see the manual AME-10.21.10 (fault-finding instruction). –

Set the V3F-20 to the “INPUT MODE 1” with the user interface unit by pressing the both arrow buttons at the same time (inspection drive switch 265 must be down). There now should be three horizontal lines on the display (see figure below):

–

Check that the elevator has passed the topmost floor.

–

Check also that the SET-UP led is off on the user interface unit MODE 2.

If the elevator stops before the topmost floor or the led S.FAIL is blinking, the set-up drive has failed and will have to be done again. Check that the shaft installation is done according to your delivery documents. After the new set-up, check that the led S.FAIL is not blinking anymore. If it is only lit, select the letter “c” on the display (between MODE 1 and 2) with the up and down arrow buttons and push CONFIRM. This resets the fault indications.

If all leds are lit then the balancing of the elevator may be incorrect. The balancing is normally 50% (the mass of the counterweight is the weight of the car + 50% of the rated load of the elevator). Another reason for that might also be the wrong motor parameters in V3F-20. In this case check the parameters (see the training manual TC 05 213 00). Motor slip –

If the temperature is too high, check the ventilation of the panel. The machine room temperature should be below 40 °C. The reason for overtemperature might also be the wrong motor parameters in V3F-20; in this case check the parameters (see the training manual TC 05 213 00). 4.3.5

Checking of the floor level –

Drive the car to each floor and record any floor level error (e.g. figure below). If the elevator stops too early, mark the error with a minus sign. If too late, mark the error with a plus sign.

–

Move the floor and door zone vanes if the error is more than 5 mm (controlled by oscillators 61:U, 61:N and 30) to adjust the floor level errors to zero. If the error is negative move the vane towards to the floor level and if positive, move it away from the floor level.

Example: FLOOR 6 5 4 3 2 1

LEVEL - 3 mm + 8 mm - 12 mm + 3 mm + 2 mm + 7 mm

Error signals detected by the EPB 2.4 control panel with V3F-20

ERROR CODE:

GENERATED IF:

The “Main contactor” signal from V3F-20 does not arrive to EPB during starting and stopping.

CONSEQUENCES:

During starting the 201:1 and 201:2 start relays are not activated and the lift stays at floor. In deceleration run, the lift oversteps the floor.

CAUSES:

- The “Main contactor” (201) signal is not activated in V3F-20 output. - Check the connection and diode polarity (in series) between EPB and V3F-20 (XM4/1 e 11). - Control the fault codes generated by V3F-20.

ERROR CODE:

GENERATED IF:

The V3F-20 drive is losing the shaft car position and it communicates to EPB that a synchronization run is needed.

CONSEQUENCES:

The controller enables the drive to start for a synchronization run.

CAUSES:

- The V3F-20 does not find the shaft signals. - The interface signals are not activated between EPB and V3F-20. - Check the switches and the signal to the shaft.

ERROR CODE:

GENERATED IF:

The V3F-20 is running set-up.

ERROR CODE:

GENERATED IF:

It indicates that the alarm signal has been activated with V3F-20.

CONSEQUENCES:

The car will arrive at the floor or stop immediately. Refer to the V3F-20 drive manual.

FAULT FINDING ON V3F-20 DRIVE This chapter is to be used by trained persons who have completed a V3F20 training course. The users must also be able to use the laptop based INVMON program for changing the V3F20 software parameters. This information is valid for V3F20 software rev 5.0 and later. The version number can be seen on the EPROM chips on the Motion Control Board 385:Al under the cover. The V3F20 has been developed to give high reliability and high resistance to failures. The engineer who works with the drive system will find much information in the forms of led's and the user interface card to aid in the correct commissioning of the drive, and to identify any difficulties that are encountered. The drive system will have passed many tests before the module is delivered for installation on site; ALL functions would have been tested and ALL parameters will have been programmed. Theoretically all that is necessary to commission a V3F20 for a new elevator would be to check that the tachometer wires are the correct polarity and the correct motor rotation direction, then to perform the set-up drive. Unfortunately there are occasionally difficulties during the life of any product. This chapter is designed to aid in the fault finding and trouble shooting of a V3F20 drive system. It is to be used in conjunction with the documentation listed below.

Related documentation SOE 11.65.3, AME 10.37.8 (Start-Up TMS600), AME 11.65.7, AR 11.65.5, AS 12.7.14, UM 11.65.3, TC OSA 213 00 and TC05 213 ME.

5.2

Fault finding procedure The first steps for trouble shooting is always to first read all LED's (inside and outside the V3F20 module), and ensure they give the correct indication for the system status. In order to drive, all green leds must be ON and all red leds OFF. Yellow leds may be ON or OFF depending on drive conditions. If one of the red leds is illuminated in the drive system: there is a failure in the boards; or in external devices, or disconnections in connectors/wiring. As the V3F20 follows the commands from the EPB control system, the elevator will not move without the MODE (i.e. Normal or Inspection drives) and START commands. The interface commands for a normal drive sequence are shown on page 22. Other drive modes are shown in SOE 11.65.3 appendix 4. It is recommended to fill in a failure report and keep a record of all jumpers at the start and during any problem investigation.

General Rules for Changing V3F20 Parameters Always use a PC if available or from User Interface menus (acceleration and jerk only). (Some changes are possible using the Motion Control Board potentiometer but this is difficult to use. Note that for software versions H08 or above a new voltage range is used - Use V20CAL50 or AS 12.7.14, issue-A parameter tables). INVMONx is used to read and change parameters in the V3F-20 drive unit. See UM-11.65.3 for details on how to use INVMON program. A set of default parameters are always initially set and are available to reset at any time. Parameters are normally configured to suit the site in the M3 control panel factory. If the program does not start, check the communication cables and the software versions. V3F20 MCB SW H01 to H04 H05 to H06

Change Parameter "Overspeed limit" changed to "tacho input saturation". New parameter ranges added. H09 or above New features added

* H07, H08 and INVMON4 were pilot versions only! - not officially released. Before changing parameters please note the following. 1 Always start by setting parameters to the V20CALx Configuration Data values. 2 Always use INVMON parameter display if possible. 3 Elevator nominal speed can not be changed without recalculating parameters with V20CAL and adjusting Tacho Test Voltage on the Motion Control Board. 4 The tacho test voltage (TTV) must be set to the specified value. 5 Check TSPL value and adjust RSPL if needed. Value for 1.0, 1.6, 1.8 and 2.0 m/s speeds are listed on the inverter board (385:A2). Otherwise calculate as 1.35/nominal speed. 6 The links on the V3F-20 Modulator Board must be set according to the frequency range specified in V20CAL results. 7 Parameter loading accuracy. – Nominal speed. – Must be loaded accurately from V20CAL results to give correct speed. – Recommended to use standard speeds using Parameter Display option. – If not possible then load special speed using Monitor Display – Max. slip (Rotor Frequency Limit); load nearest higher value. – Fsn (Frequency scaling); within ± 1 Hz. – Kl, K2, K3, K4 parameters; load nearest possible value using parameter display. If outside the selection range then use monitor display. – P factor; load nearest value. Further information about V3F-20 Fault Finding see on AME-11.65.7
