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.
