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 Eagle, “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:
Feedback A
Feedback B Ports B1 and B2
