SINAMICS S210 F07801: Drive Motor Overcurrent
What F07801 means
The motor current went above the limit allowed for this motor, so the S210 switched it off.
Symptoms
Trips when the axis accelerates, hits a load, or as soon as it is enabled.
Is it repairable?
Yes, when the motor winding, cable or converter output stage is damaged.
Common causes
- Load too high or axis jammed
- Short circuit or ground fault in the motor or OCC cable
- Current limit or control settings wrong
- Motor and converter not a matching pair
Safe checks
- 1Check the axis moves freely
- 2Megger the motor and cable with power off
- 3Confirm the motor model matches the converter it is paired with
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
