For example:
With Motor Offset selected as the commutation alignment, the parameter
ID602 (PM.007) CommutationOffset is 11.2°.
Therefore, the Commutation Offset setting for the Drive Offset type must be in
the range of 0…96.2° and 286.2…360°.
If you click Download and the input value of 200 exceeds the range, the following
warning occurs.
You must change the input value before you can click Download again and have
the input value accepted.
Run a Commutation Test
The commutation test determines an unknown commutation offset and can also
be used to determine the unknown polarity of the start-up commutation wiring.
You can also use the commutation test to verify a known commutation offset and
the polarity start-up commutation wiring.
You can decide whether to use the test results.
The following parameters are updated after commutation test:
• Phase Sequence (PM.006)
• Commutation Offset (PM.007)
• Hall Hysteresis Width (PM.008)
IMPORTANT This test mainly applies to third-party or custom permanent-magnet motors
equipped with (TTL with Hall) incremental encoders that are not available as a
catalog number in the Motion Database.
This test also applies to Kinetix MPx and Kinetix TLP motors that are available
as a catalog number in the Motion Database, and use to verify a known
commutation offset or use the test result other than the commutation offset
specified in the motion Database.
