4.2.11 Encoder_0/1/2 connector
Three connectors (one encoder interface connector per axis) are available. A standard 2.54mm pitch two row
header is used for connecting an encoder. Differential and single ended incremental encoders with/without
zero/index channel are supported.
Please connect as follows:
Single ended encoder:
GND to pin 1 and/or 2
+5V to pin 7 and/or 8
A to pin 5
N to pin 3
B to pin 9
Differential encoder:
GND to pin 1 and/or 2
+5V to pin 7 and/or 8
A+ to pin 5, A- to pin 6
N+ to pin 3, N- to pin 4
B+ to pin 9, B- to pin 10
