Description
The Schneider Electric Altivar 71 (ATV71) Variable Speed Drive is a high-performance drive designed for complex, high-power machinery. It ensures superior motor control with advanced features like Flux Vector Control (FVC) with sensor, Sensorless Flux Vector Control (SFVC), and Voltage/Frequency ratio modes, making it suitable for both asynchronous and synchronous motors. The integrated EMC filter, adjustable switching frequency (1-16 kHz), and built-in braking features provide efficiency, adaptability, and safety.
