Motor overload temperature

What does 10 mean?

According to the electronic thermal protection (ETR), the motor is too hot. This fault occurs when the motor runs with more than 100% overload for an extended period. Unresolved motor overheating risks severe motor damage or premature failure.

Complete Troubleshooting Guide

1. 1

   Check the motor for signs of physical overheating (e.g., smell, hot casing) and determine if it is mechanically overloaded.

2. 2

   Verify that the motor current set in parameter 1-24 and other motor data (1-20 to 1-25) are correctly configured to match the motor's nameplate.

3. 3

   If an external motor fan is used, ensure parameter 1-91 Motor External Fan is correctly selected.

4. 4

   Run Automatic Motor Adaptation (AMA) in parameter 1-29 to accurately tune the frequency converter to the motor, which can reduce thermal loading.
