3.4.7.4 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:
