Single-Ended Auxiliary Input Option on FEEDBACK B (YA[4]=2)
The Cello can be used as a slave by receiving the position data (on Port B1) of the master
encoder 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 ports when set up to run as a single-ended
auxiliary input:

Table 10: Single-Ended Auxiliary Encoder Option on FEEDBACK B - Pin Assignments
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).
