Control modes including closed loop vector control with Encoder, true sensorless vector control without encoder and positioning without Sensors are supported.
With scalable performance, the FR-E800 series offers a Power from 0,1 to 7,5 kW and thus a wide variety of applications. In future, these applications can be expanded to 22 kW in normal duty and 30 kW in light duty, plus 200 volts single-phase and three-phase, 400 and 575 V three-phase.
Frequency converter for heavy and rough applications
07.02.2019 | Mitsubishi Electric rounds off its frequency converter portfolio and supplies devices for additional voltage and power ranges. The drive specialist offers Compact devices up to 630 kW, a liquid-cooled series for harsh operating conditions and special devices available at short notice for crane applications and wrap applications.
After Mitsubishi Electric already covers a wide range of performance classes in the frequency converter segment, the company is now expanding its range in this area Large Capacity Inverters (LCI) from 75 kW, especially with the 800 series for low voltage. While the flagship FR-A800 is generally designed for heavy-duty operation with four load characteristics, the FR-F800 is specifically aimed at fan/pump applications. With regard to industrial networking, all new devices are equipped with an on-board Ethernet card.
Brand new within the 800 series is the series for Industrial network voltage three-phase 690 V (besides 400 and 200 V). With higher voltage, the devices can work with lower currents, which reduces the cable cross-sections. This gives you a better overview Lines of the motor, especially when many converters have to be accommodated in a small space. All large frequency converters from 75 to 630 kW are also designed in a compact design, ie ready for connection for the simple control cabinet installation and uniform commissioning.
Liquid cooled frequency converter
The inverter series of the FR-A800-LC series with liquid cooling (Liquid Cooled) are currently available in sizes from 110 to 355 kW. This series is designed for use in environments where conventional air cooling is unsuitable due to high ambient temperatures or pollution, such as tunneling, mining or heavy industry. All models are equipped with a special heat sink without cooling ribs, which prevents dust and dirt from settling. This ensures effective cooling even under the toughest operating conditions.
Special converters for crane and winding applications
Within the FR-A800Plus series are high-performance devices that are equipped with firmware with preconfigured functions for special areas of application. There are currently variants available for crane applications (FR-A800 for Cranes) and winding applications (FR-A800 for Roll-to-Roll).
The Crane variant FR-A800-CRN scores with crane-specific functionalities such as suppression of load oscillations (anti-sway control) and detection of motor slippage (falling detection). The converter detects the situation and takes countermeasures. The device also provides additional torque when lifting heavy loads or accelerates the movement of light loads in order to make crane operation more economical thanks to shorter cycle times. Thanks to PLC functionality, applications such as a position offset control for bridge cranes, which prevents twisting or twisting due to different wheel speeds, can also be programmed without an external controller.
The Roll-to-roll variant (FR-A800-R2R) is tailored in terms of functionality to all types of winding applications with varying peripheral speeds on the spools/rollers. Monitoring the tension (tension control) compensates for mechanical losses due to friction on the dancer and winding rollers, improves the winding result by reducing the tension as the diameter increases (taper function) and dampens excessive oscillation of the support or dancer rollers in the tension control, for example on paper or wire drawing machines.
“By implementing the functionality via software, our service can easily update a standard FR-A800 device from the warehouse with the operating system. In this way, we can also supply the entire performance range of the series as a special device – with the same short delivery time,” comments Christian senger, Senior Product Manager frequency converters at Mitsubishi Electric.

10.10.2017/XNUMX/XNUMX | Mitsubishi Electric is presenting a new high-performance frequency converter at this year's Motek. Linda Lewalder, Senior Product Manager Inverter, Mitsubishi Electric Europe BV, Ratingen, presents the FR-A800-E using the application example of crane systems.
Regenerative frequency converters are making a big splash in Łódź
10.11.2016/XNUMX/XNUMX | With art we can transcend the boundaries of time and, for example, travel back to ancient Greece, to the origins of the theater. But have something art and automation together? Quite simply: a modern theater cannot function without them. This application in Łódź shows the role Mitsubishi Electric plays in this.
Energy recovery by inverters in the vertical lift
30.11.2012/XNUMX/XNUMX | With the main focus energy saving solutions Mitsubishi Electric presented an approximately 5 m high presentation showing how a Hänel Lean-Lift works. The compact FR-A741 frequency converter with integrated feedback function is in the ultra-modern lift system for intralogistics tasks. The Hänel Lean-Lift stores items fully automatically and at the right height, making the best possible use of the storage space. To increase energy efficiency, the system can optionally be expanded to include the "Eco Drive" function.
He comes FR-A741 with an integrated feedback function, it converts the kinetic energy that is generated during the downward movement of the load handling device and is released into the environment unused in this performance class, into electrical energy and feeds it into the power supply network.
From there it can be used elsewhere as well as further lean lifts can be used cost-efficiently within a network. The advantages in terms of energy savings and cost reduction are clear and quickly noticeable: Depending on the travel performance of the lift, up to 40% of the energy previously required for the upward journey can be recovered and fed into the energy cycle. In this way, the CO2Reduce emissions.
Solar inverter with integrated yield optimization
With its high level of performance, the FR-A741 is particularly suitable for lifting drives or to control powerful machines with regenerative torques. Examples are applications with vertical and horizontal movements, for conveyor systems, centrifugal separators, testing machines or winding machines. Since the frequency converter and feedback unit are installed in a common housing as standard, the converter allows smaller, more cost-effective drive systems and ensures a simplified and space-saving switch cabinetconstruction. This also eliminates additional wiringeffort. Compared to using an external feedback unit, the mains-side cabling is reduced by up to 60% and the space required for installation by up to 40%, depending on the performance class.
