Power unit: Internal overtemperature

What does F30036 mean?

The internal temperature of the drive converter has exceeded its permissible operating limit. This critical condition is typically caused by insufficient cooling, a fan failure, sustained overload, or an excessively high ambient temperature. The fault triggers an OFF2 reaction, shutting down the drive, and cannot be acknowledged until the internal temperature has fallen below the permissible limit minus 5 K.

Complete Troubleshooting Guide

1. 1

   Check the ambient temperature to ensure it is within the permissible operating range for the drive.

2. 2

   Verify that the cooling fan(s) are running correctly and inspect fan elements for blockages or damage.

3. 3

   Reduce the load on the drive if it is operating under sustained overload conditions.
