3.4.7.2. Differential Auxiliary Encoder Input Option on FEEDBACK B (YA[4]=2)
The Falcon can be used as a slave by receiving the position of the master encoder data (on Port
B1) in Follower or ECAM mode. In this mode Port B2 provides differential buffered auxiliary
outputs for the next slave axis in follower or ECAM mode.
Below are the signals on the Auxiliary Feedback port when set up to run as a differential
auxiliary encoder input:
Port Pin Signal Function Pin Positions
B1 1 CHA Auxiliary channel A high input
15-Pin High Density
D-Sub Plug
B1 2 CHA- Auxiliary channel A low input
B1 3 CHB Auxiliary channel B high input
B1 4 CHB- Auxiliary channel B low input
B1 5 INDEX Auxiliary Index high input
B2 6 CHAO Buffered channel A output
B2 7 CHAO- Buffered channel A complement output

Pin Assignments
FEEDBACK B on the “top” of the Falcon has a 15-pin high density D-Sub socket. Connect the
Auxiliary Feedback cable from the feedback device to FEEDBACK B using a 15-pin, high density
D-Sub plug with a metal housing. When assembling the Auxiliary Feedback cable, follow the
instructions in Section 3.4.4 (Feedback and Control Cable Assemblies).
