SINAMICS S210 F07412: Drive Commutation Angle Incorrect (Motor Model)
What F07412 means
The S210 found that the motor's magnetic position doesn't match what the encoder reports (wrong commutation angle).
Symptoms
The motor runs rough, jumps or runs away on enable, or trips straight after starting.
Is it repairable?
Yes: encoder replacement and alignment is a standard servo motor repair.
Common causes
- Motor phases swapped
- Encoder knocked out of alignment or damaged
- Encoder speed signal disturbed
- Wrong motor data or unstable control settings
Safe checks
- 1Check the motor phase order at the converter
- 2Check whether the motor was recently repaired or the encoder replaced
- 3Inspect the OCC cable
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
