Drive: I2t motor model overtemperature

What does A07012 mean?

The internal thermal I2t model, primarily for synchronous motors, has detected that the motor's calculated temperature has exceeded an alarm threshold. This indicates that the motor is operating close to its thermal limits due to sustained load or environmental conditions. If ignored, this can lead to an actual motor overtemperature fault and potential damage.

Complete Troubleshooting Guide

1. 1

   Evaluate and, if necessary, reduce the motor's current load.

2. 2

   Verify the motor's ambient operating temperature and ensure adequate cooling.

3. 3

   Review and adjust parameter p0611 (thermal time constant) and p0605 (overtemperature fault threshold) if they are incorrectly configured for the motor.
