- Positive feedback of motor; commutation offset determination generated incorrect value for ‘P-0-0521, Effective commutation offset’.
- Positive feedback of motor after motor replacement (servicing) due to connection error.
- During commutation setting process, axis got into resonance.
- Due to low friction of mechanical system, axis moved away from its initial position at start of commutation offset setting.

Autom. Commutation: Max. Motion Range When Moving Back
Description:
- Check motor encoder signals. To do this, move motor knowing manufacturer-side setting for sense of rotation or velocity polarity and check actual position values with regard to polarity and validation. If necessary, invert polarity of motor encoder or invert two motor phases. Carry out commutation setting again.
- Check whether direction of motion (sense of rotation) of motor complies with that of motor encoder. If not, invert direction of motion of motor (invert phases) or of motor encoder.
- Set ‘search direction for sine-wave method’ to ‘increase of amplitude with priority’ in ‘P-0-0522, Control word for commutation setting’- or -Reduce value in ‘P-0-0507, Test frequency for angle acquisition’ in order modify excitation frequency for sinewave method compared to resonance frequency of axis.
- With saturation method, switch off ‘moving back to start position’, if possible on axis-side! With sine-wave method, determine new start values forP-0-0506 and P-0-0507! To do this, set P-0-0506 to ‘0’ and start command C1200!
