Motor overload temperature

What does 10 mean?

According to the electronic thermal protection (ETR), the motor is excessively hot due to prolonged operation above 100% load. This indicates a severe mechanical overload on the motor. Ignoring this alarm can lead to permanent motor damage or reduced lifespan. The frequency converter can be configured to issue a warning or alarm based on the counter reaching 100% in parameter 1-90.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Run the Automatic Motor Adaption (AMA) function (parameter 1-29) to optimize the drive's motor control parameters.

2. 4

   If sustained high loads are unavoidable, consider upsizing the motor or the frequency converter, or reducing the operational duty cycle.
