(terminals MA, MB & MC) Detection
The Form-C contact, or an open collector output, can be programmed to change states during an
overtorque detection condition.
EXAMPLE OF OVERTORQUE DETECTION
n59
setting:
2
— Overtorque enabled, only at set frequency, coast to stop
n40 setting: 6 — Output contact programmed for overtorque detection
n60 setting: 110 % — Level at which overtorque is sensed
n61 setting: 1.0 s — Time delay before overtorque event occurs
