Whistle Digital Servo Drive WHI-AR50-100

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 50 amps continuous current. Its high density allows the drive to deliver a peak of 3200 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 drive operates on DC power. The Whistle is a PCB mounted device that enables efficient and cost saving implementation.
The Whistle servo drive is designed to deliver “the highest density of power and intelligence”. While both are light and highly compact solutions.The Whistle delivers up to 4000 W of continuous power in a 2 in³ (55 x 15 x 46.5 mm or 2" x 0.6" x 1.8") 38 cc package.
The Whistle designed for OEMs. They operate from a DC power source in current, velocity, position and advanced position modes, in conjunction with a permanent-magnet synchronous brushless motor, DC brush motor, linear motor or voice coil. They are designed for use with any type of sinusoidal and trapezoidal commutation, with vector control. The Whistle can operate as a stand-alone device or as part of a multi-axis system in a distributed configuration on a real-time network. The drive is easily set up and tuned using Elmo’s Composer software tools. This Windows-based application enables users to quickly and simply configure the servo drive for optimal use with their motor. The Whistle and Tweeter, as part of the SimplIQ product line, are fully programmable with Elmo Composer motion control language.
Power to the drive is provided by a 12 to 195 VDC isolated DC power source. A “smart” control-supply algorithm enables the Whistle to operate with only one power supply in up to 100 V models with no need for an auxiliary power supply for the logic. For 200 V models, the auxiliary power supply in the range of 12 -95 V is always required.
If backup functionality is required for storing control parameters in case of power-loss, an external
12 to 95 VDC isolated supply should be connected (via the +VL terminal on the Whistle providing maximum flexibility and backup functionality when needed.
