Overcurrent trip during constant speed

What does E.OC2 mean?

This overcurrent trip occurs during constant speed operation when the inverter output current reaches or exceeds approximately 230% of its rated current. It often signals a sudden increase in load, an ongoing overload condition, or an electrical fault during steady-state operation. The inverter trips to prevent damage.

Complete Troubleshooting Guide

1. 1

   Ensure the load on the motor remains stable and within the inverter's capacity, avoiding sudden changes.

2. 2

   Inspect all wiring for the motor and output circuit for any short-circuits or ground faults.

3. 3

   Lower the setting of the stall prevention operation level (Pr. 22) to prevent nuisance trips.

4. 4

   Activate the fast-response current limit operation to improve transient current handling.
