9.2 RS-485 Communication
R type drives use ports CN6 and CN7 with a standard RJ45 (8p8C) design. They can be used to build RS-485 daisy chain networks. In
addition to the SCL command control methods, Modbus/RTU can also be used to control the drives.
9.2.1 RS-485 PIN definition
For RS-485 communication, the dual RJ45 connectors on the side of the drive can be used to build a daisy chain network system.
Pin definitions are as follows:
