9. Communication

M2 series AC servo drive supports multiple communication interface.
9.1 RS-232 communication
For Q type drives, port CN6 is used for RJ-11 communication port, it is used for RS-232 communication.
Customers can use serial communication command SCL to control the drive.

9.1.1 What is SCL

SCL or serial command language, was developed by MOONS to give users a simple way to control a
motor drive via a serial port. This eliminates the need for separate motion controllers or to supply control
signals, like Pulse & Direction, to your step and servo motor drives. It also provides an easy way to
interface to a variety of other industrial devices like PLCs, industrial computers, and HMIs, which most
often have standard or optional serial ports for communicating to other devices.
NOTE:For more details about SCL command, please download Host Command Reference manual from
MOONS website.
9.1.2 RS-232 Connections
For servo drive port CN6, RJ-11 pin definitions are as follows:
1，3，6
9.2 RS-485 Communication
R type drive uses port CN6 and CN7 for standard RJ45 (8p8C) design. This can be used to build RS-
485 daisy chain networks. In addition to the SCL command controlling methods, customers can also use
ModBUS/RTU to control the drive.
