Higher Basic Performance and Further Improved Total System Performance




Experience Powerful Performance of Multiple CPU with Ease of Use Just Like Using One CPU
You can select either the Motion CPU or the PLC CPU based on the application, allowing you to configure a system more flexibly.
The easy-to-understand flowchart form is adopted by Motion SFC for Motion control programming.
Also, the direct positioning start instruction allows you to program Motion control, such as positioning and synchronous controls, just with sequence programs.


Motion CPU Memory Expansion

  • The cam working area has been expanded to 16M bytes, enabling you to use more cam data with higher resolution.
  • The device memory has been increased to 128k words, so even multi-axis equipment requiring more devices can be applied
  • The cam data storage area has been expanded to 12M bytes. SD card is also available for storing cam data.



Ease of Use Achieved by a State-of-art CPU Buffer MemoryRevolutionary
The high-speed, high-capacity CPU buffer memory revolutionizes the data exchange between CPUs.
The PLC CPU and the Motion CPU each have a CPU buffer memory. And those buffer memories are efficiently utilized for two different purposes.

  • The 2M words CPU buffer memory (Motion CPU side) is provided as standard, which is utilized for bulky data transmission and fast data updating.
  • The CPU buffer memory (fixed-cycle communication area) allows 24 k words (4 CPUs in total) transmission between the PLC CPU and the Motion CPU every 0.222 ms. It is perfectly suited for receiving/transmitting highly synchronized data between multiple CPUs.



CPU Buffer MemoryProductivityEngineering
The Motion CPU and the PLC CPU are equipped with 2 M words and 512 k words CPU buffer memories respectively.
They allow for bulky data transmission and fast data update.

Example of using PLC CPU buffer memory
Bulky data such as cam data can be transferred by just a one-time transmission through the 512 k word buffer memory.



Example of using Motion CPU buffer memory
The data that is set on Motion CPU side can be reflected to the interlock in the sequence program without any delay.


CPU Buffer Memory (Fixed-cycle Communication Area)

Data can be transmitted every 0.222 ms between the PLC CPU and the Motion CPU. The CPU buffer memories (fixed-cycle communication area) are synchronized to the Motion control, optimizing the operation.



Motion SFC Program

The Motion control program is described in flowchart form using the Motion SFC (Sequential Function Chart) format.
The Motion SFC format program is suitable for event processing and allows the Motion CPU to perform batch control of multiple sequential machine operations, pursuing high event responsiveness.


Flowchart description is easy to 

read and understand

·         The machine operation procedure is visualized in the program by using the flowchart descriptions.

·         A process control program can be created easily, and control details can be visualized.


Controlling sequential machine operation using 
the Motion CPU

·         Servo control, I/O control, and operation commands can be combined in the Motion SFC program.

·         Motion SFC program can execute servo control by itself, eliminating the need of creating the sequence program for servo control.





High-speed Synchronous Network SSCNETIII/H




§  Communications speed is increased to 150 Mbps full duplex (equivalent to 300 Mbps half duplex), three times faster than the conventional speed.

   System response is dramatically improved.

§  Smooth control of a machine is possible using high-speed serial communications with a cycle time of 0.222 ms.

§  Synchronous communications are achieved with SSCNETIII/H, offering technical advantages for machines that require deterministic control.

§  Long distance wiring is possible up to 3200 m (10498.69 ft.) per system (maximum of 100 m (328.08 ft.) between stations x control axes up to 32 axes), suitable for large-scale systems.

§  SSCNETIII/H compatible and SSCNETIII compatible servo amplifiers can be used together.
(The communications speed when SSCNETIII compatible products are used together in the same system: 150 Mbps full duplex)

(Note): SSCNET (Servo System Controller Network)



Positioning Control

A variety of positioning controls, such as PTP control, position follow-up, and continuous trajectory control are available with the Motion controller.


Basic Positioning Control




·        To respond to various applications, the Motion controller offers various control methods such as PTP control, speed control, speed-position switching control, continuous trajectory control, position follow-up control, Speed control with fixed position stop, and high-speed oscillation control, etc.

·         Powerful auxiliary functions are available such as M-codes, the target position change function, the acceleration/deceleration time change function, and the advanced S-curve acceleration/deceleration.

·         Positioning operation can be activated by Motion SFC, or the direct positioning start instruction by the PLC CPU, etc.



Advanced Synchronous Control

The advanced synchronous control can be achieved using software instead of controlling mechanically with physical gears, shafts, clutches, speed change gears or cams etc. Additionally, a cam is easily created with the cam auto-generation function.The synchronous control can be started/ended on axis-by-axis basis.Axes in synchronous and positioning controls can be used together in one program.
Speed-torque control can be performed simultaneously with the synchronous control.






All axes are synchronized using a synchronous encoder axis or a servo input axis.

Application  Packing machines, printing machines, diaper 
          manufacturing machines, tire molder, etc.

Only two axes are in synchronization. Axis 2 is set as to synchronize to axis 1. The other axes are in positioning control.

Application  Tandem configuration, etc.



Multiple CPU advanced synchronous control

A large system can be configured thanks to the advanced synchronous control that allows up to 192-axis synchronization with high accuracy by use of three Motion CPU modules.



Synchronous Control Parameters

·    The synchronous control is easily executed just by setting parameters.

·    One of the following three can be set as the input axis: Synchronous encoder axis, Command generation axis, or Servo input axis.

·    "Command generation axis" is not counted as a control axis; therefore all the control axes can be used as output axes.

·    The cam axis can be operated in linear operation (a rotary table, a ball screw, etc.), two-way operation, or feed operation by setting cam No. and cam data.




Pressure Control

The machine is controlled so that the pressure commands match the pressure sensor values; therefore pressure is maintained constant even with a changing load. Each pressure process ("Feed", "Pressure maintaining", and "Pressure release") can be set with the Pressure Profile, and those processes can be tested on MELSOFT MT Works2, which makes a changeover and adjustment easy.



Multi-axis Adjustment Function

The multi-axis adjustment function enables simpler servo adjustment and quicker startup for machines executing multi-axis simultaneous operation, such as a tandem configuration.

·         Multi-axis simultaneous JOG operation by specifying speed and acceleration/deceleration time

·         Multi-axis simultaneous positioning

·         Multi-axis simultaneous tuning by the same settings




Machine Control Function

This Motion controller controls the simple industrial robot by installing the machine library.
The control method of the robots is a machine control which controls in a three dimensional (XYZ) Cartesian coordinates space.




Optical Hub Unit

The MR-MV200 optical hub unit can branch a single SSCNETIII/H network line in three separate directions. This enables distribution of the SSCNETIII/H compatible devices with flexible wiring arrangement. In addition, the distributed amplifier can be partly OFF for maintenance without stopping the whole system; thus, the machine availability can be improved.

·         The SSCNET connect/disconnect function of the controller allows you to power off only the desired servo amplifiers.

·         The optical hub unit is introduced just by making some changes in wiring without making any new settings.

·         Longer-distance wiring becomes available by using the optical hub unit.



(Note): Be sure to confirm that "SSCNETIII/H" is selected in the system setting when introducing the optical hub unit.
