F07801 Motor Overcurrent fault in siemens drive
F07801 Motor Overcurrent fault in siemens drive indicates that the motor current has exceeded the permissible limit defined in the parameters. The drive shuts down to protect power semiconductors.
Cause
1. Short circuit in motor or cable.
2. Motor impedance is too low.
3. Sudden load shock or mechanical blockage.
4. Current controller parameters incorrect.
Remedy
- Check motor connection (star/delta).
- Check cables for short circuit.
- Check if motor can rotate freely.
- Check current limits (p0640).
- Perform motor ID (ID run).
