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.

Complete Troubleshooting Guide

1. 1

   Evaluate the motor's operating load to ensure it does not exceed the drive's continuous or peak capacity.

2. 2

   Confirm that the motor's rated power and current are compatible with the frequency converter's specifications.

3. 3

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