D. n041 : Multi-function Output 1 – Contact OverTrq Det (NO) ( 6 ) or OverTrq
(Terminal MA Sel) Det (NC) ( 7 ): Overtorque
/ Undertorque Detection
n042 : Multi-function Output 2 – Contact
(Terminal M1 Sel)
A Form-C contact, or an N.O. contact, can be programmed to change states during an
overtorque detection condition.
EXAMPLE OF OVERTORQUE DETECTION
n077 setting: "OT/Spd/Flt" ( 3 ) — Overtorque enabled, only at set frequency,
coast to stop
n042 setting: "OverTrqDet1" ( 6 ) — Output contact programmed for overtorque
detection
n078 setting: 110 % — Level at which overtorque is sensed
n079 setting: 1.0 s — Time delay before overtorque event occurs
