Frequency converter overtemperature

What does 14 mean?

The heatsink temperature of the frequency converter has exceeded 90 °C (a warning is issued at 85 °C). Subcodes in T.14 indicate the measurement source (S1 = Measurement, S2 = Internal thermistor). Prolonged operation at high temperatures can cause irreversible damage to the drive's internal components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure the ambient temperature surrounding the frequency converter; ensure it is within the specified operating limits.

2. 4

   Review parameter settings for switching frequency; reduce it if found to be too high in relation to the ambient temperature and motor load.
