Contribution by improving efficiency and productivity
FA products (controllers/drives, robots etc.)
AC servo, MELSERVO J5 series
The MELSERVO J5 series are high performance AC servos that are also being recognized for their energy saving capabilities, for example winning the 2020 Excellence as energy-saving equipment and systems award from Japan's Director-General of the Agency for Natural Resources and Energy. Contributing to this was the use of high-resolution encoders (67,108,864 pulses/rev) that help provide stable control by lowering torque fluctuation, as well as amplifiers with a high speed response of 3.5kHz, both of these features help reduce machine cycle times and save energy. The J5 servo amplifiers are also ideal for large systems and supporting digital manufacturing, as they are compatible with the high performance networking technology CC-Link IE TSN.
Multi-axis integrated servo amplifier, MR-J5 (J4) W2/3
This integrated multi-axis servo amplifier can drive two or three servo motors from a single unit. By integrating several motors into one unit, cost, space and wiring can be reduced in addition to utilizing regenerative power to save energy.
Contribution
The multi-axis unit is up to 30% smaller compared to the single-axis servo amplifier configuration.
Simple converter, MR-CM
The common converter unit enables multiple servo amplifiers to share common bus bars, and reduce wiring, circuit breakers and contactors. It can handle numerous axes and capacity that cannot be covered by an integrated multi-axis amplifier, helping those systems to also save energy by utilizing regenerative power between the connected servo amplifiers.
Servo amplifier with separate converter, MR-J5D
The combination of MR-J5D servo amplifier and separated converter is ideal for 400V/medium capacity (1kW or more) systems. The MR-CV converter uses a regenerative power supply system that enables regenerated power that cannot be used to be returned to the supply for use in other systems. Functional safety is also supported for each axis.
General-purpose inverter, FREQROL-F800
Inverters (VFDs) are well know for contributing to saving energy, however, the FREQROL-F800 takes this to the next level. It can drive high-efficiency motors such as SF-PR IE3 energy efficient motors as well as IE4 IPM motors like the MM-EFS, this is in addition to its advanced support for energy-saving fan and pump applications.
Contribution
Power consumption reduced by about 12% in the case of cooling water pumps (ex. used for showcases)
Power consumption reduced by about 22% in the case of building air conditioning
Multi-function regenerative converter, FR-XC
This multifunctional regenerative converter supports harmonic suppression and power regeneration from the same unit. Energy-savings are achieved by diverting harvested regenerative energy to other inverters connected to the same converter. Up to 10 inverters can be supported per converter.
Contribution
Power consumption is reduced by about 30% (Ex. in the case of 70 kW operation and 30kW regeneration)
Premium geared motors
By combining IE3 high-performance energy-saving motors (greater than 0.75kW) with high efficiency gearboxes, the energy efficiency of machinery and equipment can be improved, contributing to carbon neutrality.
Contribution
30~40% reduction in losses compared to our conventional (IE1) geared motor
Industrial mechatronics products (processing machines, CNC, etc.)
Computerized numerical controllers (CNCs)
The essence of a CNC system is to contribute to the user's productivity by repeatedly performing machining processes of complex shapes, at high speed and with high accuracy. Mitsubishi Electric has added to that, technologies such as OMR-CC (optimum machine response trajectory control) which further improves machining performance by reducing cycle times and further increasing accuracy. In addition, the use of digital twins to simulate machining steps helps to reduce waste and improve tool life through load and tool tip control, contributing to greater sustainability.
Sheet metal laser machine. GX-F series
Mitsubishi Electric's latest fiber 2D laser processing machines help contribute to improved productivity and maintainability for sheet metal processing. By utilizing the new GX-F fiber laser oscillators, which have been optimized for laser processing to match the level of control to the cutting process, these machines achieve increased acceleration and consequently greater productivity. Additionally, Mitsubishi Electric's "AI Assist" function, based on its proprietry AI technology "MAISART", automatically adjusts the conditions of the laser processing machine to strengthen processing stability during continuous automatic operation. Furthermore, the dedicated fluid control technology, "AGR-eco", directly contributes to sustainability by reducing the amount of gas used to eject molten metal during laser processing.
Contribution
Assist gas consumption reduced by up to 90%
Wire-cut electrical discharge machine
Electric discharge machines process materials according to wire-cut electrical discharge machines guide an thin cutting wire through a target material, by eroding the material in the path of the cutting wire. It is a highly precise process which is energy intensive, but it allows materials which are difficult to be machined to be shaped/cut very accurately. Mitsubishi Electric's MP series is a high-end example of this using ultra-high-precision wire combined with the latest "D-CUBES" CNC control. It also utilizes advanced MAISART AI technology to improve shape accuracy, nozzle seperation and corner machining to achieve higher productivity while still managing to reduce power consumption with its power-saving mode enabling it to contribute effectively towards sustainability.
Contribution
Productivity increased (compared to our conventional model) by about 30%
Die-sinking electrical discharge machine
Die-sinking electrical discharge machines (EDMs) erode the processed material according to the shape of the electrode used, which is often controlled by CNC to manage the highly precise process. In the case of Mitsubishi Electric's SV-P series the latest "D-CUBES" NC control is combined with its preprietary AI technology, MAISART, and advanced power saving to provide an EDM system that improves machining stability, reduces electrode wear and saves energy by reducing the standby power, all helping to contribute to a more sustainable manufacturing approach.
