Pulse-and-Direction Input Option on Feedback B (YA[4]=0)
This mode is used for input of differential or single-ended pulse-and-direction position commands
on Port B1. In this mode Port B2 provides differential buffered pulse-and-direction outputs for
another axis.
Below are the signals on the Auxiliary Feedback ports when set up to run as a single-ended pulse-
and-direction input:

Note:
In models not containing absolute encoder support, it is possible to use terminals 16 and 17
for SUPRET connections.
Feedback B on the “top” of the Eagle has a 26-pin high density D-Sub socket. Connect the Auxiliary
Feedback cable from the Pulse and Direction Controller to Feedback B using a 26-pin, high density
D-Sub plug with a metal housing. When assembling the Auxiliary Feedback cable, follow the
instructions in Section 3.4.3 (Feedback Control and Communication Cable Assemblies).
