Miniature DC-Powered Digital Servo Drive-Controller with CAN Bus(CANopen)
Highly compact and intelligent digital servo drive | |
The Whistle is a series of intelligent miniature digital servo drives for DC brush and brushless motors, linear motors and voice coils. The matchbox-sized servo drive
weighs only 1.8 oz (50 g) and supports up to 20 amps. Its high density allows the
drive to deliver a peak of 2400W of power and 1600W of continuous power. Based on
Elmo's SimplIQ Motion Control technology, the Whistle 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 drive operates on DC power. The Whistle is a PCB mounted device which
enables an efficient and cost saving implementation.
Elmo also offers a range of Whistle-based products including: |
