Adjust the parameter settings and enter nameplate data.
Motor Tuning Routines
Run the following three tests in the order listed. Refer to Chapter 2 “Drive Start
Up” staring on page
for details. If these tests have already been performed,
proceed to Torque Prove Setup.
Current Tune
This routine measures motor characteristics with the brake set (brake closed).
Verify Motor Rotation and Speed Feedback Polarity
This test checks for correct motor armature and speed feedback device
connections.
Speed Tune
This routine gives better results if the connected equipment allows free motor
rotation. This routine requires the mechanical brake to open and the motor to
run.
If a “TorqPrv Spd Band” fault (F94) occurs during any of the motor tuning
routines, see page
for a list of possible errors and actions.
