Features and System Configuration
of Unit
The NJ-series Machine Automation Controllers are next-generation machine automation controllers
that provide the functionality and high-speed performance that are required for machine control. They
provide the safety, reliability, and maintainability that are required of industrial controllers.
The NJ-series Controllers provide the functionality of previous OMRON PLCs, and they also provide
the functionality that is required for motion control. Synchronized control of I/O devices on high-speed
EtherCAT can be applied to safety devices, vision systems, motion equipment, discrete I/O, and more.
OMRON offers the new Sysmac Series of control devices designed with unified communications speci-
fications and user interface specifications. The NJ-series Machine Automation Controllers are part of
the Sysmac Series. You can use them together with EtherCAT slaves, other Sysmac products, and the
Sysmac Studio Automation Software to achieve optimum functionality and ease of operation.
With a system that is created from Sysmac products, you can connect components and operate the
system through unified concepts and usability.

Features of NJ Robotics CPU Unit
The NJ Robotics CPU Unit has the following features.
Integrated Sequence Control and Motion Control
An NJ-series CPU Unit can perform both sequence control and motion control. You can simultane-
ously achieve both sequence control and multi-axes synchronized control. Sequence control,
motion control, and I/O refreshing are all executed in the same control period.
The same control period is also used for the process data communications cycle for EtherCAT. This
enables precise sequence and motion control in a fixed period with very little deviation.
Multitasking
You can assign I/O refreshing and programs to tasks and then specify execution conditions and exe-
cution order for them to flexibly combine controls that suit the application.
