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 Guitar 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: 
Auxiliary Feedback

YA[4] = 4 
(Aux. Feedback: output)
 
YA[4] = 2 
(Aux. Feedback: input)

Analog Encoder
 
applications 
where position data is required in 
the Encoder’s quadrature format. 
 Resolver applications where 
position data is required in the 
Encoder’s quadrature format. 
Tachometer or potentiometer 
applications where position data is 
required in the Encoder’s 
quadrature format. 
Any application where 
two feedbacks are used 
by the drive. 
The Auxiliary Feedback 
port serves as an input 
for the auxiliary 
incremental encoder. 
For applications such as 
Follower, ECAM, or Dual 
Loop. 
Any application where 
two feedbacks are used 
by the drive. 
The Auxiliary Feedback 
port serves as an input 
for Pulse & Direction 
Commands.
