A Form-C contact, or an open collector output, can be programmed to change states during an
overtorque detection condition.
EXAMPLE OF OVERTORQUE DETECTION
n096 setting:
2
— Overtorque enabled, only at set frequency, coast to stop
n057 setting:
6
— Output contact programmed for overtorque detection
n096 setting:
110 %
— Level at which overtorque is sensed
n099 setting:
1.0 s
— Time delay before overtorque event occurs
