Motor data identification and self-optimization
If you select the MOT ID (p1900) during basic commissioning, an alarm will be issued once
the basic commissioning has been completed.
For the motor data identification, the motor must be cold. A motor in a warm operational
condition supplies unusable measurement results.
Motor data identification for dangerous loads
Secure dangerous plant and system parts before starting the motor data identification, e.g.
by fencing off the dangerous location or lowering a suspended load to the floor.
