NJ501 Machine Automation Controller ( MAC)

The flagship of Omron’s controller lineup is the Sysmac NJ501 Machine Automation Controller (MAC); a completely redesigned hardware platform with a powerful Intel® Atom™ processor, proven for harsh environments. This fundamental shift from a rigid ASIC based architecture allows the NJ-Series to be adaptable and scalable. This ultra-compact market leading technology provides ultimate flexibility without compromising reliability and robustness that the industry has come to expect from Omron.






Omron Automation’s NJ5 controller now comes standard with OPC UA server functionality.

OPC UA is an industrial communication protocol that enables data exchange between machines and from machine to IT systems. This international standard is well linked to Industrie 4.0 and also serves as a basis for the packaging standard PackML. Since the adoption of this open standard is increasing worldwide, Omron Automation is implementing this as a standard feature on our Sysmac controllers, starting with the NJ5.

Key benefits to customers include:

  • Ease of communication from plant floor machines to IT Systems.
  • Data security through encryption and authentication.
  • Reliable and widely adopted standard available on a machine controller eliminating the need for middleware PCs and simplifying IIOT implementation projects.


The NJ Robotics controller is the core of the system architecture which uses the EtherCAT bus to provide the highest motion performance for demanding packaging applications.

The controller is able to control up to 8 robots by providing independent or synchronized movements with the others motion devices installed in the machine, such as single servo axis or group of axes.

The integration of the NJ-Robotics controller with the G5 servo systems allows you to achieve the maximum throughput in your Pick & Place applications by taking all the advantages provided by and the kinematics structure of the Delta robots.

The synchronization with multiple conveyors can be realized very easily by using specific commands which have been specially developed to optimize the cycle time of the Pick & Place applications that use Delta robots.

Robotics functions

In addition to the standard NJ functions, the Robotics CPU provides a set of specific function blocks to control multiple delta robots machine. The system allows to define the kinematics parameters to control any kind of Delta-3 robot, with or without rotational axis, and you can even create dedicated user coordinate systems to simplify the programming. The performance of the Pick & Place trajectories and any related synchronization with the conveyors can be optimized thanks to smart time-based motion commands developed specifically to match the widest through-put needs.

Key features:

  • Integrated Delta Robot control
  • Control of up to 8 Delta robots in 2 ms/ 4 Delta robots in 1 ms
  • Conveyor tracking function
  • Automatic workspace check

Real-Time OS

The NJ-Series hardware has been designed to adapt to the quickly changing demands of a machine automation controller. A typical system built around an application specific integrated circuit (ASIC) can be difficult to change and enhance. The NJ-Series uses the proven Intel® Atom™ processor to allow real-time improvements to the core of the system. This adaptability virtually guarantees a future-proof system that can lead today’s automation technology and trends.

Key Features:

  • Unmatched CPU performance
  • Advanced embedded motion
  • Unique application solutions


Accurate and Precise

Because Omron developed every aspect of the control core, run-time is predictable and reliable with no instability caused from third party code or software. With this advantage, NJ-Series functions can be accurately and precisely predicted for real world operation. The NJ501 comes in 16, 32, and 64-axis models, with features such as CAM profile simulations that provide not only position data, but additionally velocity, acceleration, and jerk. These give a detailed prediction of how the machine motion will actually perform. Only Omron can deliver such an efficient controller, ensuring your application will behave as desired.

Key Features:

  • Logic simulation
  • Motion simulation
  • Reliable operation


Motion, Logic, and Vision in ONE

With a powerful processor comes multiple systems integrated into one controller. Providing advanced motion control with proven machine logic in one unit gives your machine the ultimate advantage. The NJ-Series seamlessly combines two prominent application requirements to reduce hardware and development cost. Handshaking and other intermediate steps needed with multiple systems that create overhead, inefficiency, and delay are all eliminated while functionality and performance are increased. Tying in vision via the built-in EtherCAT interface, configured from the same software environment as the logic and motion, makes the solution unprecedented. All logic, motion, I/O, and vision response refreshing are all executed in the same control period. This enables precise sequence and motion control, in-sync with machine vision, all within a fixed period with minimal deviation.

Key Features:

  • One Controller: Tightly integrated logic, motion, and vision without sacrificing performance
  • One Software: Integrated Development Environment for logic, motion, and vision
  • One Connection: Single connection point into every aspect of the machine
