System Integration & Control Systems Design

Single module rack controls up to 128 axes

April 2002 System Integration & Control Systems Design

The System Q line of controllers is a new addition to the MELSEC PLC family introduced in the middle of last year in Europe. It features integrated motion controller functions, IT technology, full online change capability and the ability to install up to four individual CPUs, combined with even smaller product size. The PLC and motion controller can be installed on a single module rack, and together they can control up to 128 axes simultaneously. Together with its many other new products, Mitsubishi Electric is going to present the first Q system with a facility for an integrated slot PC.


Rapidly expanding markets like the IT and home entertainment industries are constantly pushing the miniaturisation and quality envelopes. To keep up, both manufacturing machines and the components used in them always have to be a step ahead of the market. Mitsubishi Electric's new MR-J2-Super servo series fulfils and exceeds these requirements, delivering outstanding synchronisation performance, extreme precision and super-short positioning times.

The state-of-the-art servo technology used in these systems satisfy the need for ever shorter cycle periods combined with more exacting production tolerances. Comprehensive automatic configuration systems enable precise calibration of servo drives like the new MR-J2-Super without the need for expensive instrumentation. The system can even register and automatically compensate for mechanical changes.

The new product philosophy 'New dimensions - automation Power from Mitsubishi Electric' stands for innovative products and optimised, application-focused operating concepts striving to give users more functionality and performance across the board. The engineering brief is as simple as it is ambitious: to develop an ideal combination of hardware and software that provides users with optimum support in all phases of their work.

Mitsubishi Electric is one of the world's biggest electronics companies with a huge pool of expertise in many high-tech fields. This makes it possible to utilise synergies in which basic research and application development form ideal complements to one another. The spectrum extends all the way from communications systems and high-speed data networks to satellite technology. The company is also one of the world's leading semiconductor manufacturers, playing a key role in the development of advanced new technologies. It is no coincidence that the resulting chips are found not only in Mitsubishi components but also in the products of many other manufacturers. This concentrated expertise is the solid foundation that Mitsubishi Electric builds on, ensuring that all its products deliver exceptional performance and reliability, with minimal failure rates. At the same time, the uncompromising commitment to reducing component number and increasing the integration of the electronics results in unusually compact products. High technology in a compact package is one of the characteristic features of all products from Mitsubishi Electric.

These hardware development efforts are accompanied by an equally uncompromising commitment to software optimisation. The main focus here is on the analysis of processes and product requirements in real, everyday industrial applications.

Close collaboration with customers' own automation experts helps to perfect the user-optimised operating concept, ensuring that all functions of Mitsubishi's innovative products can be used quickly, easily and efficiently.

All these hardware, software and customer usability efforts pay off in the form of automation products with a significant efficiency edge. The products described above are three characteristic examples of the resulting 'automation power' that Mitsubishi Electric delivers with this approach.
