Instruction Manual of -S3 Inverter for Elevator
normally required by other inverters, but similar with ordinary checking and repairing, as
described below:
a) -S3 Inverter with synchronous traction machines shall be equipped with a
synchronous PG card (5V or 5.3 V, with frequency division output).
If SIN/COS encoders are to be used, a SIN/COS PG card shall be equipped. The
number of the PG card is AS.T007. The installation and wiring of SIN/COS PG card
can be found in 4.5.2 SIN/COS PG Card for Synchronous Motors. AS.T004 cards are
an old type of SIN/COS PG card.
If UVW encoders are to be used, UVW increment PG card shall be equipped. The
number of the PG card is AS.T010. The installation and wiring of UVW increment PG
card can be found in 4.5.3 UVW Increment PG Card for Synchronous Motors.
If Endat absolute encoders are to be used, Endat absolute PG card shall be equipped.
The number of the PG card is AS.T013. The installation and wiring of Endat absolute
PG card can be found in 4.5.4 Endat Absolute PG Card for Synchronous Motors.
b) Ensure correct phase sequence of the output power line linking the Inverter and the
motor.
c) Ensure correct wiring of the encoder and reliable grounding of the shield.
d) Procedures of the autotuning:
a) Before the autotuning:
The installation and wiring of the elevator is ready for operation. The elevator
shall be put into repair state, with the safety circuit and the locking circuit
connected and without any fault. Ensure the balance of the car and the
counterweight, i.e., the elevator will not slip with the brake open. The elevator
shall be with no load.
b) Confirm parameter settings:
Confirm parameter settings through the operator:
Zero speed integral C02 = 0, current loop gain C13 = 1.00, (both by default);
Control mode E01 = 1 (for synchronous motors);
Number of poles E02, rated voltage E03, rated speed E04, rated current E05,
encoder type E09 and encoder specification E10 shall be all corrected set as
per the configuration.
c) Autotuning procedures:
Set A03 to 4 (to send the autotuning command) with the operator.
In field operation, after setting A03 to 4, hold (until the autotuning ends) the
checking button for running upward (or downward). The autotuning begins, with
the indicator lit showing Inverter running.
If SIN/COS encoder or Endat absolute encoder is used, the motor will
automatically stop at a certain position, and, about ten seconds after this, it will
resume running slowly for about ten seconds. Then it will stop again for about
ten seconds, and the Inverter will cut off the output, with the indicator off. A03
can now be seen to automatically change to 3 on the operator, indicating the
