Vancouver, WA - The MD2S is a universal programmable microstepping motor driver capable of driving size 17 to 42 stepper motors. Switch selectable resolutions from 5 to 256 microsteps per motor step and integrated resonance cancellation firmware provide smooth quiet motor performance. The standard MD2S provides selectable motor currents from 0.5 to 7.0 Amps per winding in 0.5 Amp increments. The low current option provides selectable motor currents from 0.2 to 3.6 Amps per winding in 0.05 Amp increments. The MD2S uses a novel highly efficient pump up / recirculate PWM cycle which significantly reduces power loss and motor heating.

There are two different versions available for the MD2S. The P-version accepts Step & Direction or quadrature inputs from a motor controller or optical encoder. The D-version provides a practical method to digitallly control the speed of a stepper motor without the need for a motor controller. 4 digital inputs and 8 DIP switches provide the ability to ramp up and down, run slow or fast, and reverse directions.

The MD2 family is a very flexible FPGA based product. US Digital can easily customize and tailor the firmware of the MD2 to requested parameters and behavior for special customer versions. The 4 digital inputs and 8 DIP switches of the MD2 may be assigned to perform different functions and often eliminate an external motor controller. For example: Execute a home cycle and respond to the inputs to make a series of pre-programmed moves. Simply share your request with our applications engineers for quick turnaround and a practical quote.

The MD2S may be combined with other US Digital products to construct a simple motion control building block. Any motion controller which provides step and direction outputs can be easily interfaced to the MD2S.

The MD2S is available from stock with little or no lead-time.
