3.10.4. Auxiliary Feedback – Differential Pulse-and-Direction Input
Option (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 B1 for
another axis.
Below are the signals on the Auxiliary Feedback ports when set up to run as a differential pulse-
