IGBT temperature

What does 41 mean?

The IGBT Inverter Bridge overtemperature protection has detected an excessively high short-term overload current, indicating a thermal stress condition.

• IGBT temperature approaching or exceeding operational limits.
• High temperature detected on the Insulated-Gate Bipolar Transistor.
• Overload condition causing increased IGBT temperature (P1-20).
• Inadequate cooling for the IGBT module.

Click steps to track your progress.

1. 1

   Evaluate the actual motor loading and compare it against the drive's continuous and overload current ratings.

2. 2

   Verify the motor size and nominal current rating are appropriate for the drive's specified output capacity.
