Applications

The MSD542 is suitable for a wide range of stepping motors of NEMA 17 and 34 and has been specifically designed for various kinds of machines such as X-Y tables, labeling machines, laser cutters, engraving machines and pick-place devices. It is particularly useful for the applications where low vibration, high speed and high precision are desired.
They are suitable for driving 2-phase step motors (maximum current ratings of 4.2). By using an advanced bipolar constant-current chopping technique, and a maximum input voltage of 50 VDC, they can produce more speed and power from the motor.
