Why does my Invertek Controller motor thermal overload protection trip?
- BBrianna SolisAug 21, 2025
If the Invertek Controller's motor thermal overload protection trips, make sure the correct motor nameplate current value is entered in P-08. Verify the Star or Delta wiring configuration is correct. Check if the decimal points are flashing (indicating the output current exceeds the P-08 value) and, if so, either increase the acceleration ramp (P-03) or decrease the motor load. Also, confirm that the total motor cable length is within the drive's specification and that the load is mechanically free from jams, blockages, or other mechanical faults.
