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.
