Motor Overtemperature

What does 4310 mean?

The motor temperature is excessively high (or detected as such) due to factors like excessive load, insufficient motor power, inadequate cooling, or incorrect start-up data. This condition can severely degrade motor insulation, reduce motor lifespan, and lead to premature motor failure if left unresolved.

Complete Troubleshooting Guide

1. 1

   Check motor ratings against the actual load requirements of the application.

2. 2

   Ensure the motor cooling system (e.g., fan, cooling surfaces) is clean, unobstructed, and functioning correctly.

3. 3

   Verify the motor's start-up data parameters are accurately set, including motor nominal current and thermal model settings.

4. 4

   Review Fault Function parameters related to motor temperature supervision (e.g., 30.04…30.09) and adjust limits if necessary.
