Mitsubishi Electrics RSV technology gives you class-leading power, control and flexibility. Features Designed for use with 690V supplies. Wide speed range: 200:1 operating range is possible even when the drive is used open loop PLC feature: FR-A700 programmability provides true intelligence inside the drive a simple solution for complex applications. Easy gain tuning: Compensates automatically for changes in load inertia to ensure smooth and consistent operation. Fast response: Up to 300 radians / second speed response means lightning fast reaction to sudden load changes USB port: Allows simple connection to the new FR-Configurator software for quick and easy commissioning. Power down braking: Keeps the motor under control even if the supply power is lost . Remote I/O capability: All of the drive I/O can be read or controlled over a network. Integral Radio Filter: Limits Radio Noise emissions to meet EU Directive all sizes of drive speed control: With or without torque limit allows 200:1 speed range, driving or overhauling ??? Open Loop Torque Control: Including torque at zero speed.
