11.3 Specific settings for permanent magnet synchronous motors
For permanent magnet synchronous motors pole tuning has to be performed before the first travel. The brake stays
applied. To do so, the parameters described in the table below must be set.

Pole tuning procedure in 7 steps:
To perform the described procedure the enable (EN1&EN2) inputs must be active.
1. Are motor and encoder connected properly?
2. Apply power to the inverter
3. The functions mentioned in the table above must be set.
Check that the inverter receives the encoder pulses as following: in the keypad go to Menu
4. I/O Check
and
press the down arrow key until you reach the page that shows P1, Z1, P2 and Z2 (8/8). If the motor is not moving,
the display should show
+0 p/s
after P2. Open (release) the brake and turn a little bit the motor. In this moment
the display should show a number different than 0 (positive or negative depending on the rotation direction). If the
display shows
----p/s
(or
+0 p/s
meanwhile the motor is turning) means that no signal is coming from the encoder.
In this case please check the encoder cable and the connection of the signals.
4. Set function
L03 to 1
and press FUNC/DATA key.
5. Give RUN command to the inverter from the lift controller (normally in RESCUE or INSPECTION mode). The
main contactors will be closed and current will flow through the motor producing some acoustic noise. This
procedure will take some seconds. After the procedure was finished correctly the offset value is saved and
shown in function
L04
. Write down the displayed value. If Er7 is displayed check the motor and encoder cabling
and repeat steps 5 and 6.
6. If possible, open the brake and let the cabin move some centimetres.
7. Perform steps 5 and 6 again. The result in function L04 between different measurements must not differ more
than ± 15°.
