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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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

2. 4

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