3.10.1 Main and Auxiliary Feedback Combinations

The Main Feedback is always used in motion control devices whereas Auxiliary Feedback is
often, but not always used. The Auxiliary Feedback connector has two ports (B1 and B2).
When used in combination with Main Feedback, the Auxiliary Feedback can be set, by
software, as follows:
