3.4.7.2 Differential Auxiliary Encoder Input Option on
FEEDBACK B (YA[4]=2)
The Cello 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:

B1 1 CHA
B1 2 CHA-
B1 3 CHB
B1 4 CHB-
B1 5 INDEX
B2 6 CHAO
B2 7 CHAO-

Table 3-8: Differential Auxiliary Encoder Input Option on FEEDBACK B
FEEDBACK B on the "top" of the Cello 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).
