3.4.2 A3-E and A3-F models – Wiring for CN1 I/O connector

3.4.2.1 A3-E and A3-F models – CN1 I/O connector

On A3-E and A3-F models, the CN1 I/O connector includes 7 inputs and 4 outputs for you to

define their functions. In addition, differential output signals (A+, A-, B+, B-, Z+, and Z-) for the

encoder are provided. The pin assignments are shown as follows.
