8-3 EtherCAT communication function 
 Only JSDG2S-E(L) contain this 
function 
8-3-1 EtherCAT Overview 
In this chapter, we will introduce EtherCAT communication specification, communication structure, 
object utilization and mode control of the servo driver. The chapter will be divided into: system parameter 
setting, basic characteristics, EtherCAT communication, servo control and detailed description of object 
list. Through this document, the user can have a basic understanding and use CANopen communication. 
 
8-3-2 EtherCAT Basic Features 
(1) Port message 
When the user needs to use EtherCAT 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 EtherCAT communication.
