IGBT temperature (hardware)

Hva betyr 31 ?

The IGBT Inverter Bridge overtemperature protection circuit has detected an excessively high short-term overload current, leading to a hardware-level temperature fault.

• IGBT temperature sensor failure (hardware fault).
• Overheating detected on the IGBT module.
• IGBT temperature exceeding critical threshold (P1-20).
• Poor heatsink contact or insufficient cooling.

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.
