Torque Detection
The overtorque detection circuit activates when the motor load causes the motor current to exceed
the overtorque detection level (L6-02). When an overtorque condition is detected, alarm signals can
be sent to a multi-function output. To output an overtorque detection signal, select torque detection 1
at either of the multi-function contact outputs (H2-XX=”B” or “17”).
Note: • To detect overtorque/undertorque during acceleration or deceleration, set to “2” or
“4” / “6” or “8”.
• To continue operation after overtorque/undertorque detection, set to “1” or “2” / “5”
or “6” During detection, the digital operator displays an “OL3” alarm (blinking).
• To stop the inverter after an overtorque/undertorque detection fault, set to “3” or “4”
/ “7” or “8”. During detection, the digital operator displays an “OL3/UL3” fault.

Setting Description
0 Torque detection is disabled ( factory default ).
1 Overtorque detection is enabled whenever at the speed agree level (when inverter is not accelerating or
decelerating). Continue running after detection (OT1 alarm).
2 Overtorque detection is enabled always. Continue running after detection (OT1 alarm).
3 Overtorque detection is enabled whenever at the speed agree level. Coast to a stop after detection (OT1
fault).
4 Overtorque detection is enabled always. Coast to a stop after detection (OT1 fault).
5 Undertorque detection is enabled whenever at the speed agree level (when inverter is not accelerating
or decelerating). Continue running after detection (UT1 alarm).
6 Undertorque detection is enabled always. Contnuing running after detection (UT1 alarm).
7 Undertorque detection is enabled whenver at the speed agree level. Coast to a stop after detection (UT1
fault).
8 Undertorque detection is enabled always. Coast to stop after detection (UT1 fault)
