DC Whistle Digital Servo Drive DC-WHIA10-100I
The DC Whistle is a super compact OEM panel mounted version of the Whistle, which enables fast and easy mounting and implementation.
This intelligent, digital servo drive is designed for DC brush and brushless motors linear motors and voice coils. It weighs just 273 g (only 9.6 oz) and supports up to 20 A of continuous current. Its high density enables the drive to deliver 3.3 kW of peak power and 1.6 kW of continuous power. Based on Elmo’s SimplIQ Motion Control technology, the DC Whistle is capable of operating in position, velocity and current modes and it offers 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.
Product Description
The DC Whistle series of servo drives enhances Elmo’s range of digital servo drives, recognized for having the highest power density and intelligence. The DC Whistle is a highly compact integrated solution containing a single drive.
The DC Whistle integrates Elmo’s advanced “Elmo First Control” technology, which contributes to the product’s excellent control performance, wide range of functionalities and high efficiency and reliability. The solution includes one fully separated digital motion controller featuring:
• CANopen-based networking operating simultaneously via RS-232 and CANopen DS 301, DSP 305, DSP 402 communications and featuring a third-generation programming
environment
• Current, velocity and position control loops including PT and PVT
• Commutation types
• Position feedbacks
The benefits are high dynamics and increased precision for single axis automated machines such as robots, feeders, up- and down-loaders, conveyor belts and production lines.
Power to the various DC Whistle models is provided by a 11 to 95 VDC source. A “smart” control-supply algorithm enables the DC Whistle to operate with only one power supply and there is no need for an auxiliary power supply for the logic.
If backup functionality is required for storing control parameters in case of power-loss, an external 11 to 95 VDC supply should be connected (via the VL+ terminal on the DC Whistle) providing maximum flexibility and backup functionality when needed.
