OVER SPEED TRIP
SETUP::TRIPS::OVER SPEED TRIP
Designed for SENSORLESS VEC and CLOSED-LOOP VEC Motor Control Modes.
The over speed trip 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 Closed-Loop or Sensorless Vector Control.
Parameter Descriptions
INHIBIT
Set this parameter to TRUE to disable the over speed trip.
THRESHOLD
Sets a threshold below which the trip will not operate. The value of THRESHOLD is compared to the value of SPEED
FEEDBACK (from the SPEED LOOP function block).
DELAY
Sets the time the trip must be present for before a trip is triggered.
TRIPPED
This is a diagnostic output indicating the current state of the over speed trip.
