Commutation Test
The Commutation Test determines an unknown Commutation Offset and
potentially the unknown polarity of the start-up commutation wiring. The
Commutation Test can be used also to verify both a known Commutation Offset
and the polarity start-up commutation wiring. This test is applied to third-party
or custom Permanent Magnet motors that are not available as a Catalog Number
in the Motion Database.
When a motor needs a Commutation Offset and you are not using Catalog
number as the Motor Data Source, you cannot enable the axis.
Applying the Commutation Hookup Test
There are several different cases where the Commutation Hookup Test can be
applied to a PM motor:
• Unknown Commutation Offset
• Verification of Known Commutation Offset
• Non-standard or Incorrect Wiring
