LOOP OVER SPEED
SETUP::TRIPS::LOOP OVER SPEED
Designed for BRUSHLESS SERVO Motor Control Mode.
The
loop over speed operates by looking at speed feedback and comparing it against THRESHOLD.
If the feedback 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 Brushless Servo.
Parameter Descriptions
INHIBIT
PREF: 132.01
Default: FALSE
Range: FALSE / TRUE
Set this parameter to TRUE to disable the over speed trip.
THRESHOLD
PREF: 132.02
Default: 110.00 %
Range: 0.00 to 150.00 %
Sets a threshold below which the trip will not operate. The value of THRESHOLD is a percentage of SPEED MAX (from POS
SPEED LOOP I function block) and is compared to the value of SPEED ACTUAL (from the POS SPEED LOOP OUT function
block).
DELAY
PREF: 132.03
Default: 0.00 s
Range: 0.00 to 10.00 s
Sets the time the trip must be present for before a trip is triggered.
TRIPPED
PREF: 132.04
Default: FALSE
Range: FALSE / TRUE
This is a diagnostic output indicating the current state of the loop over speed trip.
RESET
PREF: 132.05
Default: FALSE
Range: FALSE / TRUE
Resets the loop overspeed trip if set to TRUE.
