Digital Servo Drive Controller
Ideal for DC brush and DC brushless, sinusoidal and trapezoidal winding motors
The Drum is a series of intelligent digital servo drives for DC brush, brushless motors and linear motors. The powerful servo drive supports up to 90 amps continuous current. Its high density allows the drive to deliver a peak of 11,200 W of power and 9,600 W of continuous power. Based on Elmo's SimplIQ Motion Control technology, the Drum is capable of operating in position, velocity and current modes and contains a wide range of feedback and I/O options. With Elmo's Composer software,users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power.
