Product Description:

The 6410-001-C-N-N stepper drive is produced by Pacific Scientific within the 6410 Stepper Drives series. As a single-axis microstepping controller, it supplies regulated current to two-phase hybrid steppers so that indexing tables, pick-and-place heads, or feeders execute incremental motion with repeatable accuracy in automated assembly lines. By converting step commands from a PLC into phase currents, the unit delivers higher torque density than open-loop voltage drivers while keeping motor vibration low during ramping.

The drive’s bipolar current loop is modulated by a chopper running at 20 kHz, a frequency high enough to shift switching noise beyond the audible band and to ensure fine current granularity inside the motor windings. It accepts a supply range from 24 Vdc to 75 Vdc; the lower end supports stable logic operation, while the upper limit keeps the MOSFET bridge within its safe operating area. At the output stages, peak phase current reaches 7.1 A peak for rapid acceleration, whereas a continuous rating of 5 A rms supports sustained positioning loads. With an internal step filter disabled, the command interface can process pulses up to 2 MHz, allowing high-resolution interpolation from modern motion controllers.

Thermal and mechanical boundaries complete the integration data. The electronics operate from 0 °C up to 50 °C, so cabinet airflow must keep the baseplate below that point because this version ships with no auxiliary heat sink. The enclosure measures 4.30 in deep, 5.00 in high, and only 1.50 in wide, enabling dense side-by-side mounting on DIN rails when multiaxis racks are built. Storage limits span −55 °C to 70 °C for spares kept in stockrooms, and the absence of a heat sink reduces stack weight but requires the installer to bolt the backplate to a grounded panel for conduction cooling.
