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
can be sent to a multi-function output. To output an overtorque detection signal, select torque
detection 1 at either of the multi-function digital outputs (H02-0x = “B” or “18”).
Table 5-93: Torque Detection Parameter Settings
Table 5-94: Torque Detection Setting Descriptions
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 “OT1/UT1” 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 “OT1/UT1” fault.

).
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. Continuing running after detection (UT1 alarm).
7
Undertorque detection is enabled whenever 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)
