Carson City, NV—March 2006—RMS Technologies, the Driving Force in Motion Control, has developed a low cost driver that is suitable for a wide variety of motion control applications.

The R701 bipolar step motor driver operates from 24 to 80 VDC while its ability to supply phase currents ranging from 1 to 7 amps makes it a true powerhouse. The R701 also features 10x microstepping, selectable current reduction of 33%, a step frequency of 200 kHz and optically isolated step, direction, and disable/enable inputs.

For users needing less vibration and smooth performance, the R701 boasts an onboard trimpot that can be adjusted to alter the current waveform coming out of the driver and going into the step motor coils. This adjustment will decrease the amount of noise and vibration coming out of the motor enabling for smooth motion.
