Carson City, NV—July 2005—RMS Technologies, the Driving Force in Motion Control, is pleased to introduce the R325 microstepping driver with Pole Damping Technology™.

The R325 microstepping driver is capable of output currents ranging from 0.3 to 3.0 amps peak while handling +15 to 48 VDC input voltage. Selectable step resolutions from Full, 2x, 4x, 8x, 16x, 32x, 64x, 128x, and 256x microstepping are available. The R325 has hold current reduction capability with adjustable current and timeout settings. The R325 also features three optically isolated inputs and one optically isolated control output that can be used for step, direction, disable/enable, and fault detection.

The R325 features Pole Damping Technology™ (PDT). PDT enhances a step motor’s performance by creating a more accurate and smooth motion profile. PDT optimizes the microstepping performance of the step motor by outputting the correct amount of run and hold current to the motor, at the right time. Thus, each step will overcome the motor's natural tendency to want to “jump” towards the full step ON position.

Combining the R325’s 256x microstepping capability with Pole Damping Technology™ has allowed it to become the smoothest microstepping driver in the motion control industry.
