Chapter 2 Drive Start Up
Verify Speed Reference Settings and Drive Operation
Verify the following speed and direction (for four quadrant drives)
references of the drive under a load.
1. Set the speed reference to “0” (zero) using the assigned source (HIM or
analog potentiometer). See Reference Control on page
280 for more
information on speed reference sources.
2. View Par 385 [Speed Ref Out] and verify that the value is “0”.
3. Press the Start button on the HIM and slowly increase the speed
reference until full speed is reached (viewed in Par 385 [Speed Ref
Out]).
4. If using a four quadrant (regenerative) drive, press the Direction button
on the HIM and verify that the motor ramps down to “0” speed and
then to full speed in the opposite direction.
5. Press the Stop button on the HIM.
6. Verify that the drive ramps to “0” speed and stops.
ATTENTION: This test requires the free rotation of the motor shaft
combined with the load. All of the steps in the “Drive Start Up”
procedure must have been completed before completing this step.
