Note:
Removal of the absolute encoder is only possible from the rear. Due to the extremely low failure rate
of the absolute encoder, this does not represent a problem. Nevertheless a suitable free space must
be maintained behind the machine in order to permit free access for maintenance. Never joint
together the encoder cable and the motor cable or pass together through the same pipe. The
encoder shield cable must be connected to a steel plate in the cabinet.

Offset
The absolute encoder offset is set to 0 in factory. Because different inverters can have different
behavior, before running the machine it is advisable anyway to perform a “poletuning” procedure
in order to get the encoder offset. This procedure has to be performed more times checking that the
encoder offset angle doesn’t differ more than ±10° each attempt. If replicability is not achieved check
that:
- The encoder cable in not damaged or with loosen cables
- The encoder is correctly fixed (expanding flage or central screw)
- Parameters entered in the inverter are correct according to the encoder data sheet and the
encoder card is correctly installed in the inverter
For details of the procedure, refer to the frequency inverter
operating instructions.
If for any reason the encoder should be dismounted and re-mounted, the “poletuning” procedure
MUST be absolutely performed before running the machine.
