LIN Engineering has introduced an RoHS compliant version of its R256 microstepping driver/controller.

The R256-RO is capable of step resolutions ranging from 2x to 256x, operates from +12 to 40V dc, and phase current ranges from 0.1 to 2.0 amps peak.

The R256-RO features fully programmable ramps and speeds, software selectable hold and move currents, two user configurable digital I/Os; and two dedicated inputs — one optical sensor for homing and one switch closure to ground.

Commands can be issued from the Windows-based HyperTerminal program or from Lin Control, Lin Engineering’s graphical user interface created exclusively for the R256-RO.

The commands are intuitive yet simple and can be preset to execute upon power up. With the ability to store up to 16 different programs at once using the built-in 4kB of memory the R256-RO can be used as a stand alone unit with no PC connection required.
