Introduction: 2DM542 is new digital driver which adopts latest 32-bit DSP control technology and built-in microstepping technology. Users can set microsteps within 25600steps/., and any current value within rated current range. 2DM542 driver greatly improves stability and reduces noise under low subdivision. Automatic parameter tuning is integrated inside this driver, can help driver automatically adjust to best operation parameters to maximize performance of different stepper motors.
