6-7 Overtorque/Undertorque Detection Function
When an excessive load is applied to the equipment, the Inverter detects the overtorque
condition through an increase in the output current. The Inverter detects the undertor-
que condition through a decrease in the output current (or output torque) generated
when a small load is applied to the equipment.

Value Description
0 Inverter does not monitor overtorque.
1 Inverter monitors overtorque only when speed is matched. It continues operation (issues
warning) even after overtorque is detected.
2 Inverter monitors overtorque only when speed is matched. It discontinues operation
(through protective function) when overtorque is detected.
3 Inverter always monitors overtorque during operation. It continues operation (issues
warning) even after overtorque is detected.
4 Inverter always monitors overtorque during operation. It discontinues operation (through
protective function) when overtorque is detected.
Set n097 (overtorque detection function selection 2), n098 (overtorque detection level) and n099
(overtorque detection time) to enable the overtorque detection function. The Inverter will detect over-
torque when the current is the same as or higher than the detection level is output for the preset detec-
tion time.
Set a multi-function output (n057 to n059) to either of the following so that external overtorque detec-
tion output will be ON.
Set Value: 6 for overtorque detection (NO)
Set Value: 7 for overtorque detection (NC)

Note Overtorque detection will be canceled if the output current decreases from the detection level by
approximately 5% of the Inverter rated current.
