Overtorque Detection Function
When an excessive load is applied to the equipment, the Inverter detects the overtorque
condition through an increase in the output current.

Description

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 n60 for overtorque detection level and n61 for overtorque detection time to enable the overtorque
detection function. The Inverter will detect overtorque when the current the same as or higher than the
detection level is output for the preset detection time.
•
Set n40 for multi-function output to either of the following so that external overtorque detection output
will be ON.
Set Value: 6 for overtorque detection (NO)
Set Value: 7 for overtorque detection (NC)

Overtorque detection will be canceled if the output current decreases from the detection level by approxi-
