Introduction

2DM860 is newest digital stepper motor driver launched by JMC, using the latest 32-bit DSP control technology, the user can set any segment within 25600 and multi-range current value within rated current,with built-in micro technology,2DM860 driver greatly improved stability and reduced noise under subdivision. Integrating automatic parameter tuning function inside.it also can adjust the optimal operation parameters automatically for different motors to maximize the performance of the motor.

* SW4: ON=Full current, SW4 : OFF=Half current

Half-current function means that no step pulse 200ms,

the current driver outputs automatically reduced to 50% of rated output current, to prevent motor heating.
