DM856 is a digital stepper motor driver for the latest 32-bit DSP technology, suitable for driving 57,86 series motor,with excellent low-speed performance. You can set any of the subdivision within 256 and the rated current within any current value, to meet the needs of most small devices applications. The use of built-in sub-sub-technology, even in the low sub-sub-conditions, but also to achieve the effect of high-segmentation, low-speed operation is very smooth, very little noise. The internal part of the drive integrates the parameter auto-tuning function, can automatically generate the best running parameters for different motors, and maximize the performance of the motor.
