Cello - Smart and Slim Digital Servo Drive for Brush and Brushless Motors
Smart and Slim Digital Servo Drive for Brush and Brushless Motors

The Cello is a series of intelligent, slender digital servo drives for DC brush, brushless motors and linear motors. The slim servo drive supports up to 30 amps continuous current. Its high density allows the drive to deliver a peak of 6800 W of power and 3400 W of continuous power. Based on Elmo's SimplIQ Motion Control technology, the Cello is capable of operating in position, velocity and current modes and contains a wide range of feedback and I/O options. When using Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power. The Cello's slender case enables an efficient and cost saving implementation.
