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 on the Panther has three bi-
directional pins (CHA, CHB and INDEX). When used in combination with Main Feedback, the 
Auxiliary Feedback can be set, by software, as follows: 
Main Feedback Auxiliary Feedback
Software
Setting
YA[4] = 4 
(Aux. Feedback: output) 
YA[4] = 2 
(Aux. Feedback: input) 
YA[4] = 0 
(Aux. Feedback: input)
