SINAMICS S210 F30001: Drive Overcurrent
What F30001 means
The S210 measured more current in its output stage than the hardware allows and switched the motor off to protect the power transistors (IGBTs).
Symptoms
Trips as soon as the axis is enabled, while accelerating, or at random under heavy load.
Is it repairable?
Yes: power stage faults (IGBT, gate drive, current sensing) are a common converter repair.
Common causes
- Short circuit or ground fault in the motor or its OCC cable
- Wrong motor data or over-tuned control settings
- Motor rated for much more current than the converter
- Failed IGBTs or current sensing inside the converter
- Supply phase missing
Safe checks
- 1With the converter isolated and the DC link discharged, megger the motor and cable phase to ground and compare the three winding resistances
- 2Check the cable is fully seated
- 3If motor and cable test good, the converter is the likely cause
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
