Setting Description
0 Inverter does not monitor undertorque.
1 Inverter monitors undertorque only while matching speed. It continues operation (warning)
even after undertorque is detected.
2 Inverter monitors undertorque only while matching speed. It discontinues operation
(protective operation) when undertorque is detected.
3
Inverter monitors undertorque during operation. It continues operation (warning)
even after undertorque is detected.
4
Inverter monitors undertorque during operation. It discontinues operation
(protective operation) when undertorque is detected.
• Set n117 (undertorque detection function selection, n118 (undertorque detection level) and n119 (un-
dertorque detection time) to enable the undertorque detection function. The Inverter will detect under-
torque when current (or torque) the same as or lower than the detection level is output for the preset
detection time.
• Set a multi-function input (n057 to n059) to output an undertorque detection signal to an external de-
vice.
Set value: 8 for undertorque detection (NO-contact input)
Set value: 9 for undertorque detection (NC-contact input)

Set Values
• Set the undertorque detection level.
To detect the level through the output torque, set the torque in a percentage based on the motor’s rated
torque as 100%.
To detect the level through the output current, set the current in percentage based on the rated current
of the Inverter as 100%.
Note With general-purpose motors, for example, a current equivalent to approx. 60% of the motor’s
rated current will be generated when there is no load. (This current will vary according to the type
