8-2 CANopen communication function 
 Only JSDG2S contains this function
 
8-2-1 CANopen Overview 
In this chapter, we will introduce CANopen communication specification, communication structure, 
object utilization and mode control of JSDG2S servo driver. The chapter will be divided into: system 
parameter setting, basic characteristics, CANopen communication, servo control and detailed description 
of object list. Through this document, users can have a basic understanding and use CANopen 
communication. 
 
8-2-2 CANopen Basic Features 
(1) Port message 
When the user needs to CANopen communication, JSDG2S servo driver provides two RJ-45 ports 
CN5 & CN6 on the hardware. This facilitates the drive and control to a single or multiple slave stations 
when using CANopen communication.

(2) Connection   
Due to the physical characteristics of CANopen communication, when using the serial connection of 
a single or multiple slave stations, two RJ-45 ports (CN5/CN6) provided by JSDG2S servo driver do not 
have direction. The last driver needs to install a terminal resistor JSSTR01. 
 
(3) Communication Cable 
When using CANopen, the controller and servo driver use standard Ethernet cable CAT5e. It is 
recommended to use shielded Ethernet cable if an ideal communication quality is required.
