Frequency converter overtemperature

What does 14 mean?

The heatsink temperature of the frequency converter has exceeded 90°C, after a warning issued at 85°C. Subcodes indicate if the measurement itself or an internal thermistor is the source of the detection. This suggests insufficient cooling or excessive internal heat generation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure the ambient temperature around the frequency converter.

2. 4

   Verify that the switching frequency parameter is not set too high in relation to the ambient temperature and motor load.
