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 output. To output an
overtorque detection signal, select torque detection 1 at either of the multi-function contact outputs
(H02.xx = “00B,” “017,” “10B,” or “117”).
NOTE:
•
To detect overtorque during acceleration or deceleration, set to “02” or “04” / “06” or “08”.
•
To continue operation after overtorque detection, set to “01” or “02” / “05” or “06”. During
detection, the digital operator displays an “OT1/UT1” alarm (blinking).
•
To stop the inverter after an overtorque detection fault, set to “03” or “04” / “07” or “08”.
During detection, the digital operator displays an “OT1/UT1” fault.

Description
00
Torque detection is disabled (
factory default
).
01
Overtorque detection is enabled whenever at the speed agree level (when inverter 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 inverter 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)
