The A700 is a high performance drive that replaces the popular A500(L) series. It 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.
