3.4.6.2 Differential Auxiliary Encoder Input Option on
FEEDBACK B (YA[4]=2)
The Drum 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:
Port Pin Signal Function Pin Position
B2 10 CHAO Buffered channel A
output
B2 11 CHAO- Buffered channel A
complement output
B2 12 CHBO Buffered channel B
output
B2 13 CHBO- Buffered channel B
complement output
B2 14 INDEXO Buffered Index output
B2 15 INDEXO- Buffered Index
complement output
PWR
18 SUPRET Encoder supply voltage
return/COMRET
B1 19 CHA Auxiliary channel A
high input
B1 20 CHA- Auxiliary channel A low
input
B1 21 CHB Auxiliary channel B
high input
B1 22 CHB- Auxiliary channel B low
input
B1 23 INDEX Auxiliary Index high
input
B1 24 INDEX- Auxiliary Index low
input
PWR
25 +5V Encoder supply voltage
26 Pin high density
D-Sub Socket
Note: In models not containing absolute encoder support, it is possible to use
terminals 16 and 17 for SUPRET connections and use terminal 26 for +5V connection.
