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.
The A701 offers most of the features and function found in the standard A700 Series but includes built-in line regeneration that allows 100% continuous braking torque. The A701 is ideal for applications with overhauling loads or rapid start/stop cycles such as escalators, lifts & hoists and centrifuges. Other opportunities are simply customers who want to remove the problems associated with brake resistors and the heat they produce or to simplify wiring and reduce required panel space. By taking the regenerative energy from the motor and returning it to the AC line instead of transforming it into heat through a resistor, increased energy savings and improved return on investment is assured.
