Chapter 1 CoE Drive Overview ASDA A2-E 1.5 Wiring I/O Signal (CN1) Connection and Connector Terminal Layout In order to have a more flexible communication with the master, 4 programmable Digital Output (DO) and 7 programmable Digital Input (DI) are provided, which are parameter P2-18~P2-21 and P2-10~P2-16 respectively. In addition, the differential output encoder signal A+, A-, B+, B-, Z+ and Z- is also provided. The followings are the pin diagrams. CN1 Connector (female) CN1 Connector (male) rear view NOTE NC means NO CONNECTION. This terminal is for internal use only. Do not connect it, or it may damage the servo drive.
