L6: Torque Detection

The overtorque/undertorque detection function prevents damage to machinery and loads.
Overtorque is the when there is too much load on the machine. If the motor current or output torque is at the
overtorque detection level for the overtorque detection time, the drive will output an alarm and turn off the output.
Undertorque is the when a load suddenly decreases. When the motor current or output torque is at the undertorque
detection level for the undertorque detection time, the drive will outupt an alarm and turn off the output.
You can use the undertorque detection function to detect these conditions, for example:
• Machine belt cuts
• Unusual operation of the electromagnetic contactor on the drive output side
• Clogged output side air filters in fans and blowers
