Underorque detection level (n118)
Sets the undertorque detection current level in units of 1%. (Inverter rated
current = 100%) when detected by torque is selected, motor rated torque
becomes 100%.
Initial setting = 10%
Undertorque detection time (n119)
If the time for which the motor current is less than the undertorque detection
level (n118) is longer than the undertorque detection time (n119), the
undertorque detection function operates.
Initial setting = 0.1 s
Overtorque/Undertorque detection function selection 2 (n097)
When vector control mode is selected, it is possible to select whether
overtorque/undertorque detection is performed by output current or output
torque.
When V/f control mode is selected, the n097 setting becomes invalid, and
overtorque/undertorque is detected by output current.
