FP5/GP5 Operation
Torque Detection
The over/undertorque detection circuit will activate when the motor load
causes the motor current to go above or below torque detection level (n078)
respectively. When the over/undertorque condition is detected, alarm sig-
nals are sent to multi-function output terminals MA, MB and/or M1.
To output an over/undertorque detection signal, set multi-function contact
output selection n041 or n042 to “6” (N.O. contact) or “7” (N.C. contact).
·Over/undertorque Detection Function Selection (n077, Torq Det Sel)
Notes:
·To detect torque during acceleration or deceleration, select a setting that contains
“RUN”.
·To continue operation after over/undertorque detection, select a setting that contains
“Alm”. During detection, the digital operator displays “oL3” alarm (blinking).
·To stop the inverter after an over/undertorque detection fault, select a setting that
contains “Flt”. During detection, the digital operator displays “oL3” fault.
