The Mitsubishi A700 Variable Frequency Drive is a high performance drive that replaces the popular A500(L) series. The Mitsubishi A700 VFD features many of the special technologies originally developed for Mitsubishi Electric servo drive products, such as adaptive auto-tuning that automatically compensates for changes in load inertia. The result is smoother operation, less downtime and ultimately, lower operating costs. Control modes include Velocity, Torque and Positioning. Real Sensorless Vector allows Zero speed holding torque and torque control without the need for an encoder. Mitsubishi's 'Real Sensorless Vector' or RSV motor control system provides unequalled dynamic performance, ensuring a wider speed range, smoother operation and lower motor currents than ever before. RSV starts with a highly accurate motor 'map', obtained during an auto-tune procedure which applies alternating voltage to the motor and determines critical motor characteristics. At the heart of RSV is the Adaptive Flux Observer system which comparesactual motor behavior during operation with the theoretical model. Instead of a response to a change in load or speed being fixed, any variations between the theoretical and the actual motor response measured in operation are analyzed by the Flux Observer, which constantly refines the motor map as speed and load conditions change.
Wide Speed Range: 200:1 operating range is possible - even when the drive is used 'open loop
PLC Feature: 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
Brake Transistor Circuit: Included in all sizes up to 30 Hp
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 overhaulingOpen Loop Torque Control: including torque at zero speed
UL Listed for single-phase input
