3.4.6 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 on the Cello, "FEEDBACK
B" has two ports, Port B1 and Port B2. When used in combination with the Main Feedback
port, "FEEDBACK A", the ports can be set, by software, as follows:
