3.5.1 Wiring for the MODBUS communication connector
When the servo drive is connected to the PC via CN3, you can operate the servo drive, PLC, or
HMI through MODBUS using the assembly language. The CN3 connector supports the RS-485
communication interface which enables you to connect multiple servo drives simultaneously.
Note: B3 -L model: single port (Pin 1 - Pin 8); supports RS-485 only.
