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-
and-direction input:

PWR 1 +5V Encoder supply voltage
PWR 2 COMRET Common return
B1 3 CHA Auxiliary Pulse input
B1 4 CHA- Auxiliary Pulse complement input
B1 5 CHB Auxiliary Direction input
B1 6 CHB- Auxiliary Direction complement input
B1 7 NA Do not connect this pin
B1 8 NA Do not connect this pin
B2 9 CHAO Buffered Pulse output
B2 10 CHAO- Buffered Pulse complement output
B2 11 CHBO Buffered Direction output
B2 12 CHBO- Buffered Direction complement output
B2 13 NA Do not connect this pin
B2 14 NA Do not connect this pin
