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:

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).
