Issue:
ATV61 and ATV71 low torque alarm causes.

Product Line:
Altivar ATV61 and ATV71

Environment:
All

Cause:
Drive is triggering the low torque alarm

Resolution:
If there is a logic output assigned to (ttL) Low torque threshold I/O menu and the drives motor torque drops below the set or programmed threshold (50%) then the drive will trip or flash low torque threshold.

You would normally set this if you want to monitor if a belt breaks or if the motors torque drops below a set threshold.
