Torque Limit Exceeded

What does 40 mean?

This fault indicates that the drive has reached its configured torque limit. This could be due to the motor trying to accelerate or run a load that exceeds the drive's or motor's torque capabilities, or it might be intentionally set to protect mechanical components. Prolonged operation at or above the torque limit can lead to instability or mechanical stress.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review the acceleration ramp times; increasing them can reduce the peak torque demand during startup.

2. 4

   Confirm that the motor and drive are correctly sized for the application's required torque.

3. 5

   If the torque limit is intentionally set for protection, assess if the process conditions are normal or if there's an underlying mechanical issue.
