Cause : Estimated motor temperature (based on motor thermal model) has exceeded fault limit defined by parameter 31.04 Mot temp1 fltLimit.

Measured motor temperature has exceeded fault limit defined by parameter 31.04 Mot temp1 fltLimit.

Programmable fault:
31.01 Mot temp1 protection

Check motor ratings and load.

Let motor cool down.

Ensure proper motor cooling: Check cooling fan, clean cooling surfaces, etc.

Check value of fault limit.

Check motor thermal model settings (parameters 31.09...31.14).

Check that actual number of sensors corresponds to value set by parameter 31.02 Mot temp1 src.

Check motor ratings and load.

Let motor cool down.

Ensure proper motor cooling: Check cooling fan, clean cooling surfaces, etc. Check value of fault limit.
