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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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