InverteriC5Verification pending — cross-check with the official manual
iC5 OCt — Over Current
Trip — immediate stop
CAUSE
Why does it occur?
Acc/Dec time too short for load inertia (GD2); Load exceeds inverter rating; Output issued while motor free running; Output short circuit or ground fault; Mechanical brake operating too fast
REMEDY · Step by step
How to fix it?
Increase Acc/Dec time; Replace with higher capacity; Stop motor first or use speed search (H22); Check output wiring; Check mechanical brake
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
