Power card temperature

What does 69 mean?

The temperature sensor on the power card indicates that it is either too hot or too cold, exceeding safe operating limits. Extreme temperatures can severely affect the power components (IGBTs, capacitors), leading to reduced lifespan, performance issues, or immediate failure of the drive if not corrected.

Complete Troubleshooting Guide

1. 1

   Check that the ambient operating temperature is within the specified limits for the frequency converter.

2. 2

   Inspect for clogged air filters that impede airflow to the power components, and clean them if dirty.

3. 3

   Verify the proper operation of the cooling fans dedicated to the power section of the drive.

4. 4

   If all other checks are clear, inspect the power card for internal defects or damage.
