AC-Powered Digital Servo Drive-Servo Controller -with Resolver Feedback, RS-232-CANopen Communication
Intelligent digital servo drive for Brush Sinusoidal, trapezoidal Servo Motor offering higher dynamics and increased precision | |
The Tuba is a series of intelligent digital servo drives controllers for DC brush, brushless motors and linear motors. The servo drive supports up to 20 amps. Its high density allows the drive to deliver 11300 KW continuous power and 22600 KW peak power. Based on Elmo's SimplIQtechnology, the Tuba is capable of operating in position, velocity and
current modes and contains a wide range of feedback and I/O options. By using Elmo's Composer
software, users can easily perform drive setup, configuration, tuning, analysis and programming. The Tuba operates on AC power.
