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
