The Unmatched Space Saver
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 continuous current. Its high density allows the drive to deliver a peak of 2400 W of power and 1600 W 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. With Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming.
The stock model WHI-A10/60I servo drive is an enhanced version, which has all of the standard Whistle features PLUS the additional characteristics of being able to function at extreme temperature range of -15 deg C to +59 deg C. This advanced Whistle servo drive can be equipped with standard incremental encoder or analogue encoder feedback devices. The drive operates on DC power. The Whistle is a PCB mounted device that enables efficient and cost saving implementation.
