Description

The MD2S is a universal programmable microstepping (stepper) motor driver capable of driving size 17 to 42 stepper motors. 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.The MD2S family is a very flexible FPGA based product. US Digital can easily customize and tailor the firmware of the MD2S to requested parameters and behavior for special customer versions. The 4 digital inputs and 8 DIP switches of the MD2S may be assigned to perform different functions and often eliminate an external motor controller. Custom versions of the MD2S allow canned move sequences to be embedded at the factory to serve as a stand alone pre-
programmed motion control system. 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.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. >
