Run a Commutation Test
Setting the Motor and Feedback Polarity by using the Motor and Feedback Test
prior to running the Commutation Test helps ensure 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. Click Start to run the Commutation Test to determine the Commutation
Offset and Commutation Polarity.
The drive executes the Commutation Test, which includes rotating the
motor 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
You should run the Motor and Feedback Test first to determine that your
feedback is working. If the Feedback is not working, the Commutation Test
will give you incorrect results or the test will timeout.
TIP
The Kinetix 350 and the Kinetix 5500 drives do not support the
Commutation Polarity attribute.
