Frequency converter over temperature

What does 14 mean?

The frequency converter's heat sink is overheated, signifying insufficient cooling. Potential causes include blocked cooling airflow, high ambient temperature, accumulation of dust on the heatsink, or a switching frequency that is set too high in relation to the ambient conditions and motor load.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Clean any dust and debris from the heatsink fins to improve heat dissipation.

2. 4

   Review the switching frequency setting and consider reducing it if it is excessively high for the current ambient temperature and motor load conditions.
