 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)).

* The overtorque detection release width (hysteresis) is set at approx. 5% of

the Inverter rated current.

Overtorque Detection Function Selection 1 (n096)

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 alarm

(flashing).

Setting Description

0 Overtorque detection not provided.

1 Detected during constant-speed running. Oper-

ation continues after detection.

2 Detected during constant-speed running. Oper-

ation stops during detection.

3 Detected during running. Operation continues

after detection.

4 Detected during running. Operation stops dur-

ing detection.
