Torque Detection - Magnetek Impulse G+ series 4 Instruction Manual

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 5-94: Torque Detection Setting Descriptions
Torque detection is disabled (factory default).
Overtorque detection is enabled whenever at the speed agree level (when inverter is not
accelerating or decelerating). Continue running after detection (OT1 alarm).
Overtorque detection is enabled always. Continue running after detection (OT1 alarm).
Overtorque detection is enabled whenever at the speed agree level. Coast to a stop after
detection (OT1 fault).
Overtorque detection is enabled always. Coast to a stop after detection (OT1 fault).
Undertorque detection is enabled whenever at the speed agree level (when inverter is not
accelerating or decelerating). Continue running after detection (UT1 alarm).
Undertorque detection is enabled always. Continuing running after detection (UT1 alarm).
Undertorque detection is enabled whenever at the speed agree level. Coast to a stop after
detection (UT1 fault).
Undertorque detection is enabled always. Coast to stop after detection (UT1 fault)
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.
