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