IGBT temperature

What does 41 mean?

The IGBT Inverter Bridge overtemperature protection has activated, detecting excessively high short-term overload current. This can be caused by heavy motor loading or an incorrectly sized motor. Persistent high temperatures can permanently damage the IGBTs, leading to catastrophic drive failure.

Complete Troubleshooting Guide

1. 1

   Check the motor's loading conditions and reduce if operating under heavy overload.

2. 2

   Verify the motor's power rating and ensure it is appropriately matched to the drive's output capabilities.

3. 3

   Perform an identification run to optimize motor parameters and drive control.
