Frequency converter overtemperature

What does 14 mean?

The drive's heatsink temperature has exceeded its maximum safe operating limit (e.g., 90 °C or 77 °C for specific models). This is commonly caused by inadequate cooling airflow, accumulation of dust on heatsinks, high ambient temperatures, or an excessive switching frequency relative to the motor load. Sustained overtemperature will severely degrade and damage the drive's power components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify that the ambient temperature around the drive is within the specified operating limits.

2. 4

   Consider reducing the drive's switching frequency if it is excessively high for the current operating conditions and motor load.
