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, 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)).

* 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 operator will display an
3. To stop the Inverter and generate a fault at overtorque detection, set n096
to 2 or 4. At detection, the operator will display an
