1. Mounting and Setting Devices

and Hardware

• Use the hardware switches on all of the

EtherCAT slaves in the network to set the

node addresses. (The starting node

address and sequence are not specified.)

See the manuals for each slave for infor-

mation on the procedure for setting node

addresses.

Note Use the Sysmac Studio to set the

node address if there are no hardware

switches or the node address is

beyond the range that can be set with

the hardware switches.

• Connect the EtherCAT slaves and exter-

nal I/O devices.

2. Laying EtherCAT Communi-

cations Cables

Connect the EtherCAT slaves to the Ether-

CAT port of the NJ/NX-series CPU Unit.

If there is more than one EtherCAT slave,

connect them using a daisy chain or branch

wiring.

3. Creating the EtherCAT Net-

work Configuration

• Use the Sysmac Studio to create a new

project.

(a) Create EtherCAT network configu-

ration offline.

(b) Go online and create the EtherCAT

network configuration from the

actual network devices. Do so after

making the online connection that

is described in step 7.

work configuration with

EtherCAT under Con-

figurations and Setup.

4 Setting EtherCAT Slave

Variables and Axes

All EtherCAT Slaves Allocate variables to the I/O ports.

• If necessary, change the names of auto-

matically generated device variables for

each I/O port to user-defined variable

names.

Make the settings with

I/O Map under Config-

urations and Setup.

ing Device Vari-

ables for All

EtherCAT

Slaves

Only EtherCAT Servo Drive

and encoder input slaves

Set up the axes.

• Create axes (axes variables).

• Set the axis types for the Axis Variables

(to a servo axis, virtual axis, etc.), and set

the IDs of the Servo Drives.

Axis Variables are automatically registered

in the global variable table

Create and set up the

axes from Axis
