3.3.3 CN1 I/O connector (for A3-F series)
The A3-F provides 7 user-defined digital input (DI) points and 4 digital output (DO) points to
provide highly flexible communication between the servo drive and the controller. For more
information, please refer to section 3.3.5. In addition, differential type output signals for encoder
A+, A-, B+, B-, Z+, and Z- are provided. The pin assignments are shown as follows.
(1) CN1 connector (Female) (2) CN1 connector (Male)
