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 Tuba, 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:
FEED-

FEEDBACK B Ports B1 and B2
YA[4] = 4
YA[4] = 2
