MINIATURE DIGITAL SERVO DRIVE IS ONE OF SMALLEST AVAILABLE, OFFERING 20A/1000W FROM MATCHBOX- SIZED ENCLOSURE.
 
Inmoco has introduced one of the world’s smallest digital servo drives: the Whistle, from Elmo Motion Controls. The size of a matchbox and weighing just 50 grams, the PCB-mounted Whistle can deliver 10A/500W of continuous current, or 20A/1000W of peak current for use with DC brush and brushless motors and linear motors.
 
The latest introduction to Inmoco’s Elmo line of SimplIQ digital servo drives, is just 2in3 yet incorporates all the key features necessary for fast and problem-free integration of motors and drives into machines. The Whistle incorporates a digital motion controller that features CANopen networking, a position loop, a velocity loop, a current loop and a very wide range of feedback and I/O options. It also offers OEMs the benefits of simplified set-up and tuning, provided by ELMO’s Composer software.
 
The Whistle is the ideal OEM product; it is small and light enough to be PCB mounted, or installed in a motor housing or near a motor. This facility cuts costs significantly, by reducing cabling and installation time, and greatly simplifies maintenance for end-users of the product.
 
At the heart of the fully digital Whistle, and key to its high performance – is SimplIQ. This Elmo-developed technology provides on- the- fly gain scheduling for current and velocity, with PIP controllers for velocity and position. It also features advanced positioning motion control modes with PTP, PT, PVT, ECAM/follower and Dual Loop, and internal encoder interpolation (up to x 4096) based on Resolver or analogue encoder inputs. In addition, The Whistle, like all Elmo’s SimplIQ based products, has programmable opto-isolated digital I/O and host of built-in protection features.
 
 
Power to the Whistle is provided by an external 12-95 VDC isolated DC power supply. A "smart" control-supply algorithm enables the Whistle to operate with the power supply only, with no need for auxiliary power. If back-up functionality is required for storing control parameters during power-outs, an auxiliary 12-95 VDC power supply can be connected, providing maximum flexibility and optional backup functionality when needed.
 
The Whistle offers OEMs the benefits of a third generation programming structure, with motion commands, event triggered programming, event capturing interrupts and 32 KB of memory storage for user programs. Using the Composer programming software, drive set-up, configuration, tuning and analysis are all performed quickly and easily to aid integration into machines.
