5.7.5 Torque Detection
The overtorque detection circuit activates when the motor load causes the motor current to exceed the overtorque
detection level (L06.02). When an overtorque condition is detected, alarm signals will be shown on the keypad as
well, and can be sent to a multi-function digital output. To output an overtorque detection signal, select torque
detection 1 at either of the multi-function digital outputs (H02.xx = “00B,” “017,” “10B,” or “117”).
Table 5-9: Torque Detection 1 Selection Definition
NOTE:
• To detect overtorque/undertorque during acceleration or deceleration, set to “02” or “04” / “06” or “08”.
• To continue operation after overtorque/undertorque detection, set to “01” or “02” / “05” or “06”. During
detection, the keypad displays an “OT1/UT1” alarm (blinking).
• To stop after an OT1 or UT1 fault, set to “03” or “04” / “07” or “08”. During detection, the keypad displays an
“OT1/UT1” fault.

Setting Description
00 Torque detection is disabled ( default ).
01 Overtorque detection is enabled whenever at the speed agree level (when VFD is not accelerating or
decelerating). Continue running after detection (OT1 alarm).
02 Overtorque detection is enabled always. Continue running after detection (OT1 alarm).
03 Overtorque detection is enabled whenever at the speed agree level. Coast to a stop after detection (OT1 fault).
04 Overtorque detection is enabled always. Coast to a stop after detection (OT1 fault).
05 Undertorque detection is enabled whenever at the speed agree level (when VFD is not accelerating or
decelerating). Continue running after detection (UT1 alarm).
06 Undertorque detection is enabled always. Continuing running after detection (UT1 alarm).
07 Undertorque detection is enabled whenever at the speed agree level. Coast to a stop after detection (UT1 fault).
08 Undertorque detection is enabled always. Coast to stop after detection (UT1 fault)
