3.7.3.2. Differential Auxiliary Encoder Input Option on FEEDBACK B (YA[4]=2)
The DC Trombone 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 of Port B1 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:
