ST130 | Error E.oC2 – What does it mean and what can be done?
If the error message E.oC2 appears on the ST130 inverter display, it indicates an overcurrent fault during the braking phase of the connected motor.
| Possible cause | Possible solution |
| Braking time too short | Increase the braking time (F0.06) |
| Excessive inertia of motor load | Increase braking time, brake externally if needed |
| Missing or incorrect motor parameters | Enter the correct motor parameters |
| Phase loss at inverter output | Check output wiring |
| Inverter undersized for load | Select a larger-rated inverter |
