Appendix J PowerFlex 525 PM Motor Configuration
Direction Test
Perform a Direction Test. The direction test can be performed with or without
the load attached. Consider your application requirements when deciding to have
the load attached or removed from the motor. This test runs in V/Hz mode to
verify the motor polarity relative to the feedback polarity. The test confirms
motor rotation and feedback polarity. After the test is completed, a change can be
made, if required.
When configuring a PM motor, it is required to perform a Direction Test before
proceeding to the next step (Auto Tune).
If the drive was never operated before (new installation), verify that safeguards
are in place to remove power safely from the drive during an unstable situation
where the drive can produce undesired motion.
