Speed Loop Error
Description:
- Motor phases (U, V, W) interchanged so that commutation of motor is incorrect
- Incorrect encoder arrangement
- Velocity loop setting incorrect
- Commutation offset incorrect
- Drive is operated in voltage-controlled form (without encoder; U/f control); with this drive function, velocity loop monitoring does not make sense
- Motor encoder defective
- Check motor cable connection and correct phase assignment, if necessary
- Correct encoder arrangement (inverting rotational direction of encoder can possibly resolve problem
- Check velocity loop setting according to Functional Description/Application Manual
- Replace motor (in the case of MHD, MKD, MKE motors); in the case of kit motors, make commutation settings
- Deactivate velocity loop monitoring in P-0-0556
- Replace motor encoder (or motor)
