04
Thermal overload of motor / Overcurrent in brake chopper
SEW Eurodrive · MOVIFIT-FC Inverter
What does 04 mean?
This fault can signify one of two issues: either a thermal overload of the motor due to factors like high ambient temperature, inadequate heat dissipation, or excessive mechanical load; or an overcurrent condition within the brake chopper circuitry. Both conditions indicate a risk of component damage.
Common Causes
- Motor temperature exceeds safety limits.
- Overcurrent condition exceeding safe operating parameters.
- Brake chopper circuit fault or overload.
- Motor windings shorted or damaged.
- Parameter P0610 (motor thermal model) settings incorrect.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Lower the ambient temperature around the motor.
- 2
Ensure proper airflow and ventilation to prevent heat build-up around the motor.
- 3
Reduce the mechanical load on the motor.
- 4
Increase the motor speed if the application allows.
- 5
Reset the fault by switching off the DC 24 V supply voltage.
