Auxiliary Feedback Connector Pin-outs
The following tables provide the signal descriptions and pin-outs for 
the auxiliary feedback (13-pin) connectors when used with different 
feedback devices. Motor and Auxiliary Feedback Specifications begin 
on page 2-21.
Note: For TTL devices, the position count will increase when A leads 
B. For sinusoidal devices, the position count will increase when 
cosine leads sine.
