Compact and Smart Digital Servo Drive

Operating in Position, Dual Loop, Velocity and Current Mode

The Harmonica is a series of intelligent compact digital servo drives for DC brush, brushless motors and linear motors. The compact servo drive supports up to 13.3 amps continuous current.

The Harmonica is capable of delivering a peak of 2200 W of power and 1100 W of continuous power. Based on Elmo’s SimplIQ motion control technology, the Harmonica 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. The Harmonica’s small case enables efficient, cost saving implementation.
