8-9 Setting Methods
This section describes the setting methods for the Pulse Output Unit.
You can use a Pulse Output Unit as an servo axis output device if you also use the MC Function Mod-
ule.
This section describes the settings for using an NJ/NX-series Controller and the MC Function Module to
control the Pulse Output Unit.
For details on the functions of the MC Function Module, refer to the NJ/NX-series CPU Unit Motion
Control User’s Manual (Cat. No. W507).
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
N
X-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for details.
Pulse Output Units are mounted after an EtherCAT Coupler Unit to build an NX Unit Slave Terminal.
The Slave Terminal is connected through EtherCAT communications.
Refer to the NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for information on how to
build NX Unit systems.
To construct a motor control system with a Pulse Output Unit, Digital Input Units are also required to
use external sensor inputs, such as limit sensor inputs.
Connect the Digital Input Units after the EtherCAT Coupler Unit just like the Pulse Output Unit.
For information on Digital Input Units, refer to the NX-series Digital I/O Units User’s Manual (Cat. No.
W521).
Refer to 8-6 Terminal Block Arrangement on page 8-14 and Section 9 Application Example for informa-
tion on wiring external devices, such as motor drives and external sensors, to Pulse Output Units and
Digital Input Units.
Precautions for Correct Use
If you use external sensor inputs, such as limit sensors, the Pulse Output Unit and Digital Input
Units must be in the same Slave Terminal.
