Wiring ASDA-B3 3.3 Wiring for CN1 I/O connector 3.3.1 CN1 I/O connector (for M, F, and E models) 3 You can define 4 digital input (DI) points and 2 digital output (DO) points to provide highly flexible communication between the servo drive and the controller. In addition, differential type output signals, A+, A-, B+, B-, Z+, and Z-, for the encoder are provided. The pin assignments are shown as follows. 1 10 19 18 9 26 (1) CN1 connector (female); (2) CN1 connector (male) Pin assignment: Note: 1. The pulse input function is supported by the B3A series only. 2. Do not directly input the 24V power supply to the SIGN+, SIGN-, PULSE+, and PULSE- pins, or the circuit elements will be damaged.
