IGBT temperature

What does 41 mean?

The IGBT Inverter Bridge's overtemperature protection has detected an excessively high short-term overload current, causing the IGBTs to heat up rapidly. This fault indicates severe thermal stress on the power stage, which can lead to component failure and ultimately, drive damage if not addressed promptly.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Perform a motor identification run to optimize the drive's control parameters for the specific motor and load, improving thermal management.
