AC High Power Super Compact
12-20A/230VAC (1,3 Phase)
12-20A/460VAC (3 Phase)

Description

AC-Powered Digital Servo Drive-Servo Controller -with Resolver Feedback, RS-232-CANopen Communication

Intelligent digital servo drive that offers improved dynamics and increased precision for brush, sinusoidal and trapezoidal servo motors

The Tuba is a series of intelligent digital servo drive controllers for DC brush, brushless motors and linear motors. The servo drive supports up to 20 Amps continuous current.

Its high density allows the drive to deliver 11.3 kW continuous power and 22.6 kW peak power. Based on Elmo’s SimplIQ technology, the Tuba 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 Tuba operates on AC power.
