Stepper Motor Drive

TEMPE, AZ — The RoadRunner SoftStep R213S microstepping motor drive provides ultra-smooth, quiet stepper motor operation. The intelligent on board processor developed by Testra treats the input steps as small vector moves and smoothly chains them together with 250 or 256 micro-steps per regular motor step with controlled accelerations. Dual chopper stabilized current comparators, along with auto-calibration, gets rid of communication discontinuities and maintains a near perfect sine wave drive, further reducing motor noise while increasing accuracy and stability.

The drives are shipped with jumpers installed with a divisor setting of 10 to make them Gecko drive compatible, but the jumpers can be reconfigured by the user as needed.

Measuring 2.5” x 2.5” x 0.825”, input power is 20VDC – 80VDC, current Drive is 1 to 7 amp. Other features include resistor programmable current, opto-isolated inputs, step, direction, disable input (not isolated), and step frequency to 5Mhz. Available options for OEMs include optional custom waveforms to match individual motor characteristics; CW, CCW input; user programmable waveform; step on+ or – transition; custom current reduction, 3.3V input drive and 50 Khz chop frequency.
