Product Description:

The 6410-031-N-N-N is a microstep drive manufactured by Pacific Scientific within the 6410 Stepper Drives series. It interfaces between a motion controller’s step-direction outputs and a two-phase stepper motor, regulating phase current and step resolution to produce smooth incremental movement. By combining current chopping with selectable microstepping, the drive allows quieter operation, reduced mid-range resonance, and finer positioning accuracy in automated conveyors, labeling stations, and light material-handling axes. The compact board-level format also enables installation inside distributed control enclosures where space is limited.

Input power is a DC bus, and the unit accepts up to 75 Vdc, permitting higher back-EMF overhead for rapid acceleration. Operation can start as low as 24 Vdc, which matches common 24 to 48 V supplies on small machines. The drive current is programmable from 0.625 A RMS to 5.0 A RMS, letting a single model support NEMA-17 through NEMA-34 motors without coil overheating. Current regulation uses a fixed chopping rate of 20 kHz so switching noise remains above the audible band. Because no integral heat sink is supplied, adequate panel conduction or forced air is required to keep the electronics within operating limits, and the housing measures 5.0 inches high, 1.5 inches wide, and 4.3 inches deep.

The 6410 controller can track input streams up to 2 MHz, giving sufficient headroom for high-speed indexing even when fine microstep ratios are selected. For installations where excessive pulse noise is present, an internal digital filter limits accepted commands to 500 kHz, preventing false counts. Resolution programming spans from full-step operation up to 51,200 steps/rev for precision moves that require very fine position increments. The unit weighs only 1.0 lb, which simplifies DIN-rail or bulkhead mounting in space-constrained cabinets.
