5.6 Feedback from incremental encoder
In place of the resolver it is possible to use an incremental encoder (must be expressly requested
when placing your order). When the feedback is incremental encoder see par. “
setting feedback”.
Modifications at this bit are available only after restarting of the drive.
The phasing procedure must be run upon every drive start up.
It’s possible choose among two type of procedure, and it’s necessary that the motor must be free to
rotate, also when the motor is mounted into the system (the brake of the motor must be disable).
During the phasing procedure 1, the drive checks the connections, and the movement of the motor is
broadest, so this procedure is recommended for the first time.

Command phasing 1. It’s necessary to disable the
software (b40.9=0); enable the hardware
(b41.5=1), and driver OK (Pr23=0).
The motor executes two movements and the last is
about 90° degree electric, with control sign of the
encoder feedback. Introduce the correct number of
the motor poles (Pr29).

Status:
0 if positive result
2 if wrong enabling
3 if positive feedback
4 if wrong motor poles (tolerance ±22.5 electric
degrees)
5 if drive not ready (Pr23 ≠0 or open inrush)
