MD-55D / MD-255D / MD-355D / SD-5D
Five (5) Phase micro-step driver which is compatible with all models of
Kohzu motorized stages. Driver is compact size and low cost. Step angles
of MD-55D / 255D / 355D can be set in 16 ways, with 250 divisions
maximum which allows smooth and high precision positioning.
