2 Specifications and Application Procedures
2 - 12 NX-series Position Interface Units User’s Manual (W524)
This section describes the procedures to use Position Interface Units without the MC Function Module.
 EtherCAT Slave Terminal Configuration and Settings
Mount the Position Interface Units after an EtherCAT Coupler Unit to configure an EtherCAT Slave
Terminal.
To use the Position Interface Units, you must configure the EtherCAT network as well as configure
and set the EtherCAT Slave Terminal.
Refer to the following sections for information on the I/O data assigned to the I/O entry mappings for
Position Interface Units:
6-7 I/O Data Specifications on page 6-34, 7-7 I/O Data Specifications on
page 7-30, and 8-8 I/O Data Specifications on page 8-31.
Refer to the NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for information on
how to assign the I/O data of Position Interface Units.
 Parameter Settings of the Position Interface Units
Set the parameters for the Position Interface Units.
The settings are different for each model of Position Interface Unit.
Refer to the following sections for details: 6-6-5 Differences in I/O Refreshing Methods Based on the
Controller on page 6-29, 7-6-5 Differences in I/O Refreshing Methods Based on the Controller on
page 7-21, and 8-7-4 Differences in I/O Refreshing Methods Based on the Controller on page 8-28.
 Assigning Device Variables to I/O Ports
Assign device variables to I/O ports.
You can then control the Position Interface Units through these device variables.
Refer to the following sections for a list of the I/O ports for the Position Interface Units: 6-7-1 Data
Items for Allocation to I/O on page 6-34, 7-7-1 Data Items for Allocation to I/O on page 7-30, and
8-8-1 Data Items for Allocation to I/O on page 8-31.
Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for the procedures to
assign device variables to I/O ports.
 Displaying the I/O Map and Watch Tab Page
Open the I/O Map or Watch Tab Page to view the values of the device variables that you assigned to
the I/O ports.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No W504-E1-06 or higher) for the
procedures to display the I/O Map and Watch Tab Page.
 Programming
You cannot use motion control instructions to control the Position Interface Units if you do not use
the MC Function Module. To perform motion control in the user program, write all motion control
logic by reading and writing the device variables that are assigned to the I/O ports.
