Motion Control - ElmoMC

Cornet

AC-powered PWM Digital Servo Drive-Servo Controller

Includes built in resolver feedback support for brush and brushless motors

The Cornet is a series of intelligent digital servo drives for DC brush, brushless motors and linear motors. The servo drive supports up to 9 amps continuous current. Its high density allows the drive to deliver 3400 W continuous power and 6800 W peak power. Based on Elmo's SimplIQ Motion Control technology, the Cornet 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 Cornet operates on AC power.
