3.4.7.2 Differential Auxiliary Encoder Input Option on
FEEDBACK B (YA[4]=2)
The Tuba 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 Position
B1 1 INDEX Auxiliary Index high input
B1 2 CHB Auxiliary Channel B high input
B1 3 CHA Auxiliary Channel A high input
PWR 4 +5V Encoder supply voltage
PWR 5 SUPRET Encoder Supply return
B2 6 CHAO Buffered Channel A output
B2 7 CHBO Buffered Channel B output
B2 8 INDEXO Buffered Index output

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