1 Features and System Configuration
1 - 10 NX-series Position Interface Units User’s Manual (W524)
To use the Position Interface Units, mount them on an EtherCAT Slave Terminal and connect the Slave
Terminal to the built-in EtherCAT port on an NJ/NX-series CPU Unit.
In this configuration, you can use the MC Function Module of the NJ/NX-series Controller to perform
motion control.
For details on the MC Function Module, refer to the NJ/NX-series CPU Unit Motion Control User’s Man-
ual (Cat. No. W507).

troller
Letter Item Description
(A)
EtherCAT master
*1 The EtherCAT master manages the EtherCAT network, monitors the status of the slaves,
and exchanges I/O data with the slaves.
(B) EtherCAT Coupler
Unit (NX-ECC20

)
The EtherCAT Coupler Unit is an interface that performs process data communications
over an EtherCAT network between the NX Units and the EtherCAT master.
The I/O data for the NX Units is accumulated in the EtherCAT Coupler Unit and then all of
the data is exchanged with the EtherCAT master at the same time.
The EtherCAT Coupler Unit can also perform message communications (SDO communi-
cations) with the EtherCAT master.
(C) NX Units The NX Units perform I/O processing with connected external devices.
Process data communications with the EtherCAT master are performed through the Ether-
CAT Coupler Unit.
(D) End Cover The End Cover is attached to the end of the Slave Terminal.
(E) Support Software
(Sysmac Studio) The Sysmac Studio runs on a personal computer and it is used to configure the EtherCAT
network and EtherCAT Slave Terminals, and to program, monitor, and troubleshoot the
Controller.
You can connect the computer in which the Sysmac Studio is installed to the peripheral
USB port or built-in EtherNet/IP port on an NJ/NX-series CPU Unit. Or you can connect it
to the peripheral USB port on the EtherCAT Coupler Unit to set up the EtherCAT Slave Ter-
minal.
