Torque Detection - Omron VARISPEED V7 User Manual

Torque Detection

If an excessive load is applied to the machine, an increase in the output
current can be detected to output an alarm signal to multi-function out-
put terminal MA, MB, P1, or P2.
To output an overtorque detection signal, set one of the output terminal
function selections n057 to n059 for overtorque detection (Setting: 6
(NO contact) or 7 (NC contact)).
Multi-function Output Signal

Terminal MA, MB, P1, or P2
* The overtorque detection release width (hysteresis) is set at approx. 5% of
the Inverter rated current.

1. To detect overtorque during acceleration/deceleration, set n096 to 3 or 4.
2. To continue operation after overtorque detection, set n096 to 1 or 3.
During detection, the Digital Operator will display an
(flashing).
3. To stop the Inverter and generate a fault at overtorque detection, set n096
