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.

3. Precautions

(1) Understand the specifications of devices that are used in the system. Allow some margin

for ratings and performance. Provide safety measures, such as for installing a safety

circuit, in order to ensure safety and minimize the risk of abnormal occurrences.

(2) To ensure system safety, 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.

(3) The user is encouraged to confirm the standards and regulations that the system must

conform to.

(4) It is prohibited to copy, reproduce, or distribute a part or the whole of this document

without the permission of OMRON Corporation.

(5) The information contained in this document is current as of September 2022.

It is subject to change without prior notice for improvement purposes.

The following notations are used in this document.

Indicates a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury, or may result in serious

injury or death. Additionally, there may be severe property

damage.

Indicates a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury, or property damage.

Precautions for Correct Use

Precautions on what to do and what not to do to ensure correct operation and performance.

Additional Information

Additional information to read as required.

This information is provided to increase understanding or make operations easier.

Symbols

The filled circle symbol indicates operations that you must carry out.

The specific operation is shown in the circle and explained in text.

This example indicates a “general precaution” for something that you must

carry out.

4. Overview

This document describes the procedures used to operate the OMRON servo drivers

(G5-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/CK5M-CPU11, 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.

representative for information on how to procure the ESI file.

Precautions for Correct Use

Do not share the connection line of EtherCAT communications with other Ethernet networks.

Do not use devices for Ethernet such as a switching hub.

Use the Ethernet cable (double shielding with aluminum tape and braiding) of Category 5 or

higher, and use the shielded connector of Category 5 or higher.

Connect the cable shield to the connector hood at both ends of the cable.

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.

6.1. Workflow

Take the following steps to operate the motion control devices after connecting the Controller

and Servo Driver via EtherCAT.
