4.  Overview 
 
This document describes the procedures used to operate the OMRON servo drivers 
(1S-series EtherCAT communication built-in type, hereafter referred to as Servo Driver) using 
the motion program for OMRON Programmable Multi-Axis Controller (hereafter referred to as 
the Controller), model CK3E-□□□□/CK3M-CPU11/ CK5M-CPU11/, as well as for 
checking the operation. 
In the document, Servo Driver and servomotors to be connected are collectively called motion 
control devices. Servo Driver may also be referred to as a slave depending on the 
explanation. 
 
Refer to Section 6. EtherCAT Connection Procedure to learn about the setting methods and 
key points to perform PDO communications via EtherCAT. In this document, the motion 
program is used to check operations. 
 
The range of usage of this document is checking the connection of motion 
control devices connected via EtherCAT. When using instructions and 
constructing systems that are not described in this document, always read and 
follow the information provided in all Safety Precautions and Precautions for 
Safe Use in the manuals for each device that is used in the system.
