Miniature DC-Powered Digital Servo Drive
Ultralight and intelligent digital servo drive
The Tweeter is a series of ultralight intelligent digital servo drives for DC brush and brushless motors, linear motors and voice coils. Despite weighing only 0.95
oz (27 g), the Tweeter can support up to 3.3 amps continuous current. Its high density allows the drive
to deliver a peak of 400 W of power and 200 W of continuous power. Based on Elmo's SimplIQ
technology, the Tweeter 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 Tweeter is a PCB mounted device which enables an efficient, cost saving implementation. |
