NX-series Pulse Output Unit
NX-PG0@@@
CSM_NX-PG0____DS_E_4_5
Positioning with Pulse Input Type Motor
Drivers Such As Stepper Motor Drive
• The MC Function Modules of the NJ-series Machine
Automation Controller enable pulse outputs for motor control.
• The same motion control instructions as those for Servomotor
control allow you to program single-axis PTP control and
interpolation.
Features
• When the motion control instructions of the MC Function Modules of the NJ/NX-series Machine Automation Controller are used, number of
usable units is the same as the maximum number of axes controlled by the NJ/NX-series Controller.
• High-speed remote I/O control with communications cycle as fast as 125 μs.*1
• Synchronous I/O refreshing or Task Period Prioritized refreshing *2, can be selected for refreshing with the NX-series EtherCAT Coupler.
• Latch function (2 external latch inputs)
• Maximum pulse output speed: 500 kpps
*1. When using the NX-EC01@@ together with the NX701-@@@@ and NX-ECC203.
*2. Task Period Prioritized refreshing is available when the NX-ECC203 is used together.

*1. When the Unit is connected to an NJ-series CPU, you can use these inputs by adding a Digital Input Unit and assigning MC Function Module functions.
*2. The pulse output from a Pulse Output Unit is a 24-VDC PNP open collector output. Connect an external current-limiting resistor according to
the input specifications of the connected motor drive.
Example: For a G5-series Servo Drive, connect a 2-kΩ (1/2-W) resistor in series.

OVERALL EQUIPMENT OR SYSTEM.
Programmable Products.
Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence
thereof.
Performance Data.
Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining
suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate
it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.
Errors and Omissions.
Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is
assumed for clerical, typographical or proofreading errors or omissions.
