Run a Commutation Test
Set the Motor and Feedback Polarity by using the Motor and Feedback Test
before running the Commutation Test. This setting helps make sure that the
motor spins in the correct direction for the Commutation Test for monitoring
the Commutation Angle.
Follow these steps to run a commutation test.
1. To run the Commutation Test to determine the Commutation Offset
and Commutation Polarity, click Start.
The drive executes the Commutation Test, which includes motor
rotation in the positive direction by at least one revolution.
The results of the Commutation Test appear.
2. If the results are satisfactory, click Accept Test Results.
Commutation Offset and Polarity results are stored in the controller as
part of the axis configuration that is sent to the drive during
initialization.
TIP Run the Motor and Feedback Test first to determine that your feedback is
working. If the Feedback is not working, the Commutation Test gives you
incorrect results or the test times out.
TIP The Kinetix 350, Kinetix 5500, and PowerFlex 527 drives do not
support the Commutation Polarity attribute.
