This section describes the procedures to use Position Interface Units with the MC Function Module.
For details on procedures for which references are not specified, refer to the NJ/NX-series CPU Unit
Motion Control User's Manual (Cat. No. W507).
 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.
Precautions for Correct Use
To assign a Position Interface Unit to an axis in the MC Function Module, you must assign NX
Unit I/O Data Active Status

in the EtherCAT Coupler Unit. Replace “

” with 15, 31,
63, or 125 according to the highest NX Unit number of the EtherCAT Coupler Units. Refer to the
NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for details.
 Parameter Settings of the Position Interface Units
