2. Terms and Definitions
Term Explanation and Definition
Slave Slaves are devices connected to EtherCAT. There are various types of
slaves such as servo drivers handling position data and I/O terminals
handling the bit signals.
Object Represents information such as in-slave data and parameters.
PDO
communications
(Communications
using Process Data
Objects)
One type of EtherCAT communications in which Process Data Objects
(PDOs) are used to exchange information cyclically and in real time.
This is also called “process data communications”.
PDO Mapping The association of objects used for PDO communications.
PDO Entry PDO entries are the pointers to individual objects used for PDO
mapping.
ESI file
(EtherCAT Slave
Information file)
An ESI file contains information unique to the EtherCAT slaves in XML
format.
You can load ESI files into the Power PMAC IDE, to easily allocate
slave process data and make other settings.
ENI file
(EtherCAT Network
Information file)
An ENI file contains the network configuration information related to
EtherCAT slaves.
Power PMAC IDE This computer software is used to configure the Controller, create user
programs, and monitor the programs.
PMAC is an acronym for Programmable Multi-Axis Controller.

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 OMROM Programmable Multi-Axis Controller (hereafter referred to as
the Controller), model CK3E-□□□□/CK3M-CPU11/NY51□-A□□□, 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.

6. EtherCAT Connection Procedure
This section describes the procedures to connect the Controller and Servo Driver via
EtherCAT, and to operate the motion control devices. The description assumes that the
Controller is set to factory default.
If an uninitialized Controller is used, the motion control devices may perform
unexpected operations upon power-on depending on the Controller status,
resulting in a personal injury to the user.
To prevent unexpected operations of motion control devices, be sure to initialize
the Controller before connecting the motion control devices and the Controller
via Ethernet cable.
