SINAMICS S210 F07575: Drive Motor Encoder Not Ready
What F07575 means
The motor encoder told the S210 it isn't ready, so the converter can't control the motor.
Symptoms
The axis won't enable; often appears together with other encoder messages.
Is it repairable?
Yes: encoder replacement on the motor or repair of the converter's encoder interface.
Common causes
- Encoder failed to start up
- Damaged OCC cable or connector
- Faulty encoder in the 1FK2 motor
- Encoder interface in the converter faulty
Safe checks
- 1Read the other encoder messages in the list
- 2Reseat or swap the OCC cable
- 3Try the motor on a known-good converter if one is available
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
