Torque limit

What does ALARM 12 mean?

The motor's torque has exceeded the value set in parameter 4-16 Torque Limit Motor Mode or the generator torque limit in parameter 4-17 Torque Limit Generator Mode. This condition can be a warning or escalate to an alarm and trip, protecting the mechanical system from excessive stress.

Complete Troubleshooting Guide

1. 1

   If the motor torque limit is exceeded during ramp-up, extend the ramp-up time.

2. 2

   If the generator torque limit is exceeded during ramp-down, extend the ramp-down time.

3. 3

   If the torque limit occurs during steady-state operation, increase the torque limit, but ensure the mechanical system can safely operate at the higher torque.

4. 4

   Check the application for any excessive current draw on the motor.
