4.12 Motor data identification and rotating measurement
Note
If speed control optimization is used for operation with encoder, then the control operating
mode is automatically reset to speed control without encoder, so that the encoder test
can be carried out.

DANGER
During speed controller optimization, the drive triggers movements in the motor that can
reach the maximum motor speed. The emergency STOP functions must be fully
operational during commissioning. To protect the machines and personnel, the relevant
safety regulations must be observed.
