Frequency inverters provides maximum drive performance.

One of the highlights of the Mitsubishi Electric next generation range is their new FR-A800 inverter. The ultramodern drive has been specially designed for use in classic plant and machinery and with its maximum output and performance, increased efficiency and productivity are guaranteed. At the same time, the latest in-house technology concepts will enable the optimisation of plant efficiency and energy balance. FR-A800 inverters are particularly user-friendly and offer numerous network connections. The FR-A800 series is the result of the further development of the successful FR-A700 series. It complies with international regulations and standards and is equipped with the very latest safety functions.
With the FR-A800 series of inverters, the company introduces its very latest drive technology with an output range extending from 750 watts up to a maximum of 1 megawatt. They provide for the operation of both standard asynchronous motors and IPM/SPM motor technology. USB host and USB device functions guarantee user-friendly programming and parameterisation as well as data logging functionality. It is also fully integrated in Mitsubishi Electric’s iQ Works programming environment. The built-in operation panel and multitext display allows the easy and intuitive operation of the components.

Real sensorless vector control enables maximum speed and torque quality up to a maximum frequency of 400 Hz to be achieved. An overload capability of 250 per cent during the start-up phase will ensure reliable start-up, especially under difficult operating conditions. Minimum terminal scan times of less than three milliseconds will guarantee the fastest possible response. At the same time speed rise times of less than 80 milliseconds will help to ensure maximum performance and improved productivity.

Four overload scenarios offer optimised plant planning while three additional slots expand the range of possible applications. Functional safety up to PLe/SIL3 guarantees operation in situations ranging from simple emergency stops to complex press actuation. The new series of inverters offers a total of eleven network options including CC-Link, SSCNET, Profibus-DP, Profinet, Ethernet/IP, EtherCAT, LONworks and Modbus RTU, enabling them to be used worldwide. Full backward compatibility with the FR-A700 series guarantees that components can be replaced easily and safely.

“Like all Mitsubishi Electric inverters, the FR-A800 series comes with numerous protective, safety and overload functions, high-quality temperature-resistant capacitors, continuously lubricated encapsulated cooling fans and double-coated control and circuit boards. Integrated maintenance timers indicate component fatigue. All these features increase the equipment availability by providing predictive and condition-based maintenance funtionalities”, explains Oliver Endres, European Product Manager Energy / LVS / Inverter of Mitsubishi Electric’s Factory Automation-European Business Group.

And now, Mitsubishi Electric has added dust and splash-proof versions with an IP55 protection rating to its FR-A800 series of modern frequency inverters. Specially designed for harsh environments and tailored to the requirements of pumps and fans, the drives are highly robust and ideally suited for use in industrial and commercial building automation systems as well as in heating, ventilation and air-conditioning systems
