___IN Depth Product description ___
The MD2S is a universal programmable microstepping (stepper) motor driver capable of driving size 17 to 42 stepper motors. Peak motor currents are selectable from 0.5 to 7.0 Amps per winding in 0.5 Amp increments. The L-option (low current) is selectable from 0.20 to 3.6 Amps per winding in 0.05 Amp increments. The MD2S is powered by a single supply voltage from +16 to +50VDC.
The MD2S-D is a digital speed control version of the MD2S. This version provides a practical method to spin 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.
Conventional drivers use a pump-up / pump-down PWM cycle that generates undesirable ripple current and eddy current losses.  In contrast, the MD2S uses a more efficient pump-up / recirculate modified PWM cycle that significantly reduces this power loss and the resulting heat. This is most noticeable when the motor is at or near zero speed.
