- Fault name
- Over current verified
- Type
- WARNING/ALARM verified
- Cause
- The inverter peak current limit (approximately 200% of the rated current) is exceeded. The warning lasts approximately 1.5 s, then the frequency converter trips and issues an alarm. Shock loading or quick acceleration with high-inertia loads can cause this fault. If the acceleration during ramp- up is quick, the fault can also appear after kinetic back-up. If extended mechanical brake control is selected, a trip can be reset externally. verified
- Corrective action
- • Remove the power and check if the motor shaft can be turned. • Check that the motor size matches the frequency converter. • Check that the motor data is correct in parameters 1-20 to 1-25. verified
