3.10.3. Auxiliary Feedback - Differential Encoder Input Option
(YA[4]=2)
The Whistle 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 of B1 for the next slave axis in Follower or ECAM mode.
Below are the signals on the Auxiliary Feedback ports when the Whistle Auxiliary Feedback port
is set up to run as a differential Auxiliary input:
Port Pin Signal Function
PWR 1 +5V Encoder supply voltage
PWR 2 COMRET Common return
B1 3 CHA Auxiliary channel A input
B1 4 CHA- Auxiliary channel A complement input
B1 5 CHB Auxiliary channel B input
B1 6 CHB- Auxiliary channel B complement input
B1 7 INDEX Auxiliary Index Input
B1 8 INDEX- Auxiliary Index complement Input
B2 9 CHAO Buffered Channel A output
B2 10 CHAO- Buffered Channel A complement output
B2 11 CHBO Buffered channel B output
B2 12 CHBO- Buffered channel B complement output
B2 13 INDEXO Buffered Index output
B2 14 INDEXO- Buffered Index complement output
PWR 15 +5V Encoder supply voltage
PWR 16 COMRET Common return
