4.12 Motor data identification and rotating measurement

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.

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.
