What does 31 mean?
The IGBT Inverter Bridge's hardware overtemperature protection has activated, detecting an excessively high short-term overload current. This indicates that the power semiconductors are experiencing dangerous thermal stress, risking permanent damage or reduced lifespan if the overload persists.
Complete Troubleshooting Guide
- 1
Check the motor's mechanical loading to ensure it is within the drive's continuous operating limits.
- 2
Verify that the motor size and rating are appropriate for the frequency converter's specifications.
- 3
Perform a motor identification run to ensure all motor parameters are accurately tuned for optimal control and thermal management.
