Introduction:
JMC 2DM860 is new digital stepper motor driver which adopts latest 32-bit DSP control technology and built-in microstepping technology. Users can set microsteps within 25600step/rev, and any current value within rated current range. 2DM860 driver greatly improves stability and reduces noise under low subdivision. Automatic parameter tuning is integrated inside this driver, can help automatically adjust to the best operation parameters to maximize performance of different stepper motors.
