The document provides specifications for two NextStep microstepping drives, the NextStep and NextStep-240. The NextStep has step sizes ranging from 5000 to 50000 and can output currents from 0-7.9 amps in increments of 0.1 amps. The NextStep-240 has step sizes ranging from 5000 to 50000 and can output currents from 0-3.9 amps in increments of 0.1 amps. Both drives have protection from short circuits, under voltage, over temperature, interlocks, and over voltage. The NextStep has a package size of 137.16 x 137.16 x 63.5 mm.

MICROSTEPPING DRIVES
An IDC NextStep microstepping drive incorporates all the standard
features you expect from a competitive, world class motor/drive package
and much more, all at a competitive price. IDC has taken step motor
performance to a new level of innovation providing performance
enhancements, convenience, and quality resulting in genuine value. The
NextStep’s revolutionary design consumes significantly less panel space
than other fully packaged systems, delivers an industry leading 17
watts/in3, is designed for long life and durability, and most important, the
NextStep increases your system’s throughput to levels previously
unachievable using open-loop positioning systems.
NextStep in Functionality and Flexibility
