Torque limit

What does 12 mean?

The motor torque has exceeded the programmed limits in parameter 4-16 (Motor Mode) or 4-17 (Generator Mode). This can be caused by excessive load, rapid acceleration/deceleration, or incorrect limit settings. Persistent torque limiting can hinder application performance or cause unexpected stops.

Complete Troubleshooting Guide

1. 1

   If the motor torque limit is exceeded during ramp up or generator torque limit during ramp down, extend the respective ramp time.

2. 2

   If the torque limit occurs while running, cautiously increase the torque limit (e.g., 4-16, 4-17), ensuring the system can operate safely at a higher torque.

3. 3

   Check the application for any excessive current draw on the motor or mechanical binding that could cause high torque.
