3.5 Wiring for the CN3 connector (RS-485 / high-speed
communication)
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 two
commonly used communication interfaces, RS-485 and CAN. This enables you to connect
multiple servo drives simultaneously.
Note:
1.
A3-L: single port (Pin 1 – Pin 8); supports RS-485 only and does not support high-speed
communication (CANopen).
2.
A3-M: dual ports; supports both RS-485 and high-speed communication (CANopen).
(1) CN3 connector (female) (2) CN3 connector (male)
Pin assignment (same for both connectors):
Pin No.
