3.4.7.3 Single-ended Auxiliary Input Option on FEEDBACK B
(YA[4]=2)
The Tuba can be used as a slave by receiving the position data of the master encoder (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 ports when set up to run as a single-ended
auxiliary encoder input:
Port Pin Signal Function Pin Position
B1 1 INDEX Auxiliary Index input
B1 2 CHB Auxiliary Channel B input
B1 3 CHA Auxiliary Channel A 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
