Chapter 6-4
6-4 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.

Value Description
Inverter does not monitor overtorque.
Inverter monitors overtorque only when speed is matched. It continues operation (issues warning) even after overtorque is detected.
Inverter monitors overtorque only when speed is matched. It discontinues operation (through protective function) when overtorque is detected.
Inverter always monitors overtorque during operation. It continues operation (issues warning) even after overtorque is detected.
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)
