[. . . ] Before tuning make sure that the control mode is set to PM Closed Loop Vector (A1-02 = 6). START * Remove the ropes so that the motor can rotate freely * Set the Base Block inputs BB and BB1 Switch ON the power supply if it is OFF Does a OPE06 fault occur? Yes Check parameter * F1-01 * n8-35 Switch off the power supply and check if the right PG card is correctley installed No * Check parameter n8-35 * If EnDat / Hiperface is used - check the encoder power supply - check the CLOCK and DATA signal wiring * Switch off the power supply. Does a CPF24 fault occur? Yes No Does a OPE02 fault occur? Yes * Check if the correct PG constant (F1-01) and absolute encoder resolution (F1-21) has been set. * Refer to: page 26, Operator Programming Errors (OPE) No Set mechanical constants: S3-13 - Traction sheave diameter S3-14 - Roping S3-15 - Gear ratio and eliminate the fault source Open the brake, close the motor contactor, turn the motor slowly in Forward direction*1 and check monitor U1-05. Does PGO (no encoder feedback) occur? Yes * Check the wiring * Check/readjust the encoder power supply No No Is the sign of the U1-05 value positive (not -)? * Check the encoder wiring * Change parameter F1-05 Yes Set the autotuning parameters: T2-04 - Motor rated current T1-01 = 0 - Rotational Tuning T2-05 - Motor pole number T2-01 - Motor rated power T2-09 - Encoder resolution T2-02 - Motor base frequency T2-10 - Motor voltage constant T2-03 - Motor rated voltage Press the UP button until the "Tuning Ready" display appears Refer to page 27, Auto-tuning Faults Close the motor contactor(s) and press the RUN button Wait until tuning is finsihed and eliminate the fault source No (Fault code is displayed) Tuning successful? Yes ("Tuning successful" is displayed) Open the contactors, open the baseblock inputs and close the brake FINISH * 1. Forward direction means: The direction the motor turns with an UP command at terminal S1 (i. e. with a clockwise rotating 3 phase supply and U-U, V-V, W-W wiring between inverter and motor). Usually the direction is clockwise seen from the motor shaft (traction sheave) side. Refer to the motor instruction manual or consult the manufacturer for details about the rotation direction. Fig 7 Autotuning for Permanent Magnet Motors EN-17 PM Motor Encoder Offset Tuning Fig 8 shows the autotuning procedure for an encoder offset tuning. The procedure should be performed if the encoder has been changed or has not been aligned correctly. Before tuning make sure that PM losed loop vector control is selected (A1-02 = 6) and that the E1and E5parameters are set up correctly. START No Is it possible to remove the ropes ? Yes Remove the ropes. Set the Base Block inputs BB and BB1 Balance the car so that it does not move with open brakes. Note: The tuning accuracy will be lower in this tuning mode Switch ON the power supply if it is OFF Does a OPE06 fault occur? Yes Check parameter * F1-01 * n8-35 Switch off the power supply and check if PG card is correctly installed No * Check parameter n8-35 * If EnDat / Hiperface is used - check the encoder power supply - check the CLOCK and DATA signal wiring * Switch off the power supply. Does a CPF24 fault occur? Yes No Does a OPE02 fault occur? Yes * Check if the correct PG constant (F1-01) and absolute encoder resolution (F1-21) has been set. * Refer to: and eliminate the fault source page 26, Operator Programming Errors (OPE) No Open the brake, close the motor contactor, turn the motor slowly in Forward direction*1 and check monitor U1-05. Does PGO (no encoder feedback) occur? Yes * Check the wiring * Check/readjust the encoder power supply No No Is the sign of the U1-05 value positive (not -)? * Check the encoder wiring * Change parameter F1-05 Yes Set: T1-01 = 4 - Encoder Offset Tuning Press the UP button until the "Tuning Ready" display appears. Refer to Close the motor contactor(s) and press the RUN key. Wait until the tuning is finished. page 27, Auto-tuning Faults and eliminate the fault source. Tuning successful? No (Fault code is displayed) Yes ("Tuning successful" display is shown) Open the contactors, open the base block inputs and close the brake FINISH * 1. Forward direction means: The direction the motor turns with an UP command at terminal S1 (i. e. with a clockwise rotating 3 phase supply and U-U, V-V, W-W wiring between inverter and motor).

Fig 8 Encoder Offset Autotuning EN-18 Ride Profile and Sequence Setup Up and Down Commands and Speed Reference Selection Up / Down Command Source Selection The input source for the Up and Down signal can be selected in parameter b1-02. The factory setting is Up/ Down command by the terminals S1/S2 (b1-02 = 1). Travel start in Up or Down direction To start in the elevator in Up or Down direction the following conditions have to be fulfilled: · At least one speed reference must be selected if digital inputs are used for speed reference selection. · The hardware base block signal (Terminal BB and BB1) must be set (not base block condition). · The Up/Down signal must be set to start in the corresponding direction. Travel stop The inverter can be stopped as follows: · The direction command (UP or Down) signal is removed. · The speed reference selection signal is removed if digital inputs are used for speed reference selection. · If d1-18 is set to 3 and all speed inputs are removed Speed Reference Source Selection The speed reference source can be selected using parameter b1-01. The factory setting is the digital operator (b1-01 = 0), i. e. [. . . ] C5-07 ASR switching frequency Sets the frequency for switching between Proportion Gain 1, 2, 3 and Integral Time 1, 2, 3. Mid. output freFrequency (Hz) E1-08 quency voltage (VB) To set V/f characteristics in a straight Min. output fre- line, set the same values for E1-07 and E1-10 quency voltage E1-09. In this case, the setting for E1-08 will be disregarded. [. . . ]
