ELMO DC Whistle is one of smallest & most powerful digital servos drives available

Inmoco has introduced the super-compact SimplIQ DC Whistle, one of the world’s smallest panel mounted digital servo drives, from Elmo Motion Control. Weighing just 273 grams, the ultra-compact, high power density DC Whistle can deliver 20A (3.3 kW) 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, the DC Whistle measures just 115mm x 75mm x 25.8mm, yet incorporates all the key features necessary for fast and problem-free integration of motors and drives into machines. The DC 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 wall mounted, along the back of the unit, (it can also be mounted horizontally on a metal surface) or ‘book shelf’ mounted, along the side. This mounting flexibility cuts installation costs and simplifies maintenance for end-users of the product.

At the heart of the fully digital DC 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 DC Whistle, like all Elmo’s SimplIQ based products, has programmable opto-isolated digital I/O and host of built-in protection features.

The DC 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.

Power to the Whistle is provided by an external 12-95 VDC isolated DC power supply. A smart control-supply algorithm enables the DC 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.
