Message from Factory Automation Systems Group

Delivering Devices, Equipment, and Solutions That Help Reduce Energy Usage during Production to Customers around the World

Yoshikazu Miyata
Executive Officer
In Charge of Factory Automation Systems

Devices and equipment used in industrial mechatronics are essential to adding value and enhancing the competitiveness of a business through quality and productivity improvements for customers in the manufacturing industry. Mitsubishi Electric's Factory Automation Systems Group provides devices and systems that possess high energy-saving capability for production facilities in factories, where the bulk of energy is consumed.

We are helping our customers reduce the total cost of development, production and maintenance by taking advantage of our factory automation and information technologies, and are continuously supporting our customers' improvement activities. We aim to propose solutions for manufacturing that keep one step ahead, and we are also strongly supportive of manufacturing and management optimization from the aspects of production, product quality, the environment, safety, and security. Various data collected in real time from a production site go through preliminary processing according to usage, and data to be used onsite is then fed back immediately to the production site, while the data required for use at higher levels as information is supplied to IT systems. In this way, we provide an overall environment that is to the fullest extent optimized for manufacturing. We are also contributing to energy savings, one of our goals, by continuing to promote improvements using such a manufacturing environment.

In addition, we are verifying productivity and facility utilization ratios through the operation of a "model factory where e-F@ctory solutions are being used" at the Nagoya Works. In the factory, a large number of activities have indicated the benefits of reducing CO2 from production, including improved productivity, shorter lead times, and less product quality loss.

We are committed to contributing to our customers' manufacturing activities by continuing to propose combinations of our highly energy-efficient factory automation products and cutting-edge factory automation solutions.

Mitsubishi Integrated FA Solution, e-F@ctory

Climate change

The primary goal of the integrated FA solution, e-F@ctory, is to reduce the total cost of development, manufacturing, and maintenance processes. e-F@ctory utilizes sophisticated technologies and information management to optimize factory operations through improved productivity, quality, and energy consumption, thus shaping the factory model of the future. The e-F@ctory received the "2015 Frost & Sullivan Southeast Asia Enabling Technology Leadership Award."

Programmable Controller MELSEC iQ-R Series

Climate change

Programmable controller MELSEC iQ-R series

A newly developed high-speed system bus enables the MELSEC iQ-R Series to achieve a processing capacity 40 times greater than the MELSEC-Q Series. Furthermore, variation in control cycles has been minimized to ensure maximum stability in manufacturing quality by utilizing the synchronized operation of controllers connected via networks. This contributes to further improving the efficiency of production facilities and optimizing factory operations.
In recent years, the application of controllers has expanded to water treatment facilities, photovoltaic power generation systems, and electric power monitoring systems, also contributing to energy savings and environmental improvements for customers outside of the FA field.

Fiber 2D Laser Processing Machines eX-F Series

Climate change

Fiber 2D laser processing machines eX-F series

The eX-F Series incorporates fiber laser technology into our Fiber 2D Laser Processing Machines eX Series to achieve superior oscillation efficiency. It includes various advanced features, such as Mitsubishi Electric's original high-efficiency servomotor, servo amplifier, and inverter-control cooling unit. This has achieved a 60% reduction in power consumption*1. In addition, the Eco Mode setting, which stops machine functions in stages, reduces power consumption by as much as 70% during standby*2. Energy-saving operation is further supported by the visualization of power and gas consumption via a monitor that displays energy use.

Industrial Robot MELFA FR Series

Climate change

Industrial robot MELFA FR series

In response to the need for an efficient parts supply network, shorter startup time, and the flexibility to handle a variety of parts, we have developed intelligent technologies that use force sensors, 3D vision sensors, multifunctional electric hands, and more. Compared to conventional mass-production lines producing a single part, it is now possible to produce small lots of multiple items, productivity has been improved, the production area footprint has been reduced, and production efficiency and product quality have been improved even as system startup time has been reduced. We contribute to reducing energy consumption through the optimization of customers' production systems.

Energy­-Saving Motor
SF­-PR Superline Premium Series

Climate change

Energy-saving motor
SF-PR superline premium series energy-saving motor

If all of the approximately 100 million standard motors in Japan were replaced with highly efficient Top Runner-compliant motors (equivalent to IE3*3), calculations show that some 15.5 billion kWh of power usage could be saved annually. The same holds true for other countries as well, indicating the important role that IE3-compliant industrial motors will play in improving natural environments in Japan and abroad. The Top Runner-compliant SF-PR Series was awarded the Japan Machinery Federation Chairman's Award at the fiscal 2015 (35th) Excellence in Energy-Conservation Equipment Awards as an induction motor applying cutting-edge, high-efficiency design technology.

IE3: Premium efficiency class under IEC60034-30, which classifies single-speed, three-phase, cage-induction motors into energy-efficiency classes.

Energy Measuring Unit Eco-Monitor Series

Climate change

Energy measuring units

By installing our energy measuring unit in switchboards and distribution boards, it is possible to measure various data such as energy consumption, voltage, and current. This unit not only measures and analyzes the overall energy consumption of factories and buildings, but also the individual energy consumption of departments, sections, lines, and equipment, and achieves efficient energy usage by managing the basic unit. The product won the Minister of Land, Infrastructure and Transport prize at the 55th product contest held during the JECA FAIR 2016 organized by the Japan Electrical Construction Association.

Reducing CO2 during Production – Fukuyama Works Smart Meter Production Building

Climate change

The Fukuyama Works Smart Meter Production Building is in charge of producing smart meters, which are essential to building next-generation energy networks. This facility has implemented the following measures in order to reduce CO2 emissions from production.

  • Reducing heat transfer by 84% for the rooftop and 42% for the wall through full insulation measures and adopting a windowless structure for the production area
  • Achieving greater energy efficiency by preventing excessive heating and cooling onsite using a centrally managing a City Multi air conditioner system with Move-Eye equipped with the G-150AD Web-based central controller
  • Raising the efficiency of air conditioner operations by using an energy-efficient, compact air-cooled heat pump chiller
  • Achieving significant energy savings by installing LED lighting (650 straight tubes and 24 ceiling lights) on the building's interior and roof overhangs (reducing energy consumption by 28,400kWh/year and reducing replacement costs by 370,000 yen/year)
  • Further reducing energy consumption from lighting and air conditioning by approximately 7% (total savings approximately 120,000 yen per year) by means of a FEMS (Factory Energy Management System), which provides optimal control through linked production of lighting and air conditioning energy.
