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.
AccessoriesThe Cable Starter Kit for the Cornet includes the basic user cables required for installing the Cornet digital servo drive. This do-it-yourself accessory is accompanied by documentation that provides details for grounding and attaching the required connectors, as a complement to the Cornet User Guide.
