SPEED FBK TRIP
SETUP::TRIPS::SPEED FBK TRIP
CLOSED-LOOP VEC Motor Control Mode only.
The speed feed back trip operates by looking at speed error and comparing it against THRESHOLD.
If the error exceeds this threshold for a period greater than DELAY, then a trip is triggered. The trip is only active while the
drive is operating in Closed-Loop Vector Control and not in Autotune. When using the drive in torque control, this trip should
be disabled to prevent nuisance tripping by setting INHIBIT to TRUE.
Torque control is defined as operating in torque or current limit, or if the TORQ DMD ISOLATE parameter in the SPEED
LOOP function block is TRUE.
Set this parameter to TRUE to disable the speed feedback trip.
ault: 50.00 %
Sets a threshold below which the trip will not operate. The value of THRESHOLD is compared to the value of SPEED ERROR
(from the SPEED LOOP function block).
Sets the time the trip must be present for before a trip is triggered.
This is a diagnostic output indicating the current state of the speed feedback trip.
