1. The DM422D is a new generation high-performance digital stepper driver based on DSP with advanced control algorithm.
2. The motors driven by DM422D can run with much smaller noise and much less vibration than other drivers in the market.
3. The DM422D possess the feature of lower noise, lower vibration, and lower heating.
4. The DM422D’s voltage is DC 20V-40V. It is suitable for all the 2 phases hybrid stepper motor whose current is less than 2.2A.
5. The maximum step number of DM422D is 6400 steps/rev.
6. Its current range 0.5A-2.2A.
7. DM422D has automatic semi-flow, over-voltage, under voltage and over-current protection function.

It can be applied in a variety of small scale automation equipment and instruments,  such as labeling machine, cutting machine, packing machine, drawing machine,  engraving machine, CNC machine and so on. It always performs well when it is used  in equipment which  requires  for low-vibration, low-noise, high-precision and high-velocity.
