Getting maximum drive performance for plant and machinery
06 May 2014
A new drive from Mitsubishi Electric has been designed for use in high-end applications, where it is said to offer maximum output and performance, increased efficiency and reliability.
Drive technology advances enable the optimisation of plant efficiency and energy balance. The FR-A800 series builds on, and will eventually replace, the FR-A700 series. It complies with international regulations and standards and is equipped with the latest safety functionality.
The drive series has an output range extending from 750 watts up to a maximum of 1 megawatt. They are able to drive both standard asynchronous motors and IPM/SPM motor technology. A built in PLC – based on the Mitsubishi L Series – ensures that the drive gives the user wide scope for application specific coding. This is fully password protected to protect valuable IP. A powerful built in positioning function is said to further enhance flexibility.
USB host and USB device are designed to ensure user-friendly programming and parameterisation as well as data logging capability. It is also fully integrated into the company’s iQ Works programming environment. The built-in operation panel and optional LCD display allows easy and intuitive operation.
Real sensorless and full vector control enables maximum speed and torque accuracy, while an overload capability of 250% during the start-up phase will ensure trouble free start-up, even for the most arduous of applications. 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 options offer maximum flexibility, while three additional slots expand the range of possible applications. Functional safety up to PLe/SIL3 are said to guarantee operation in situations ranging from simple emergency stops to complex press actuation. Full backwards compatibility with the FR-A700 series guarantees that components can be replaced easily and safely.
