5.5.3 –Encoder Connectors
The Encoder connector provides a means to interface an
encoder or pulse and direction input to the controller.
There are two identical connectors provided, one for
each axis. The encoder 5 volt output is restricted to 100
milli-amps of current per axis. We highly recommend
the use of twisted-pair (approximately 6 twists per foot)
shielded cable for all encoder wiring to minimize inter-
ference problems. The following signal should be
twisted together A+ with A-, B+ with B-, I+ with I- and
+5V with GND.
