Product Description:
The 6410-001-N-N-K is a single-axis stepper drive produced by Pacific Scientific as part of the 6410 Stepper Drives series. It converts step and direction signals from a motion controller into phase-modulated current for two-phase hybrid stepper motors used on positioning tables, dispensers, and small gantries. By chopping the DC bus internally, the unit regulates winding current without an external heat sink and fits compactly into control enclosures. This arrangement allows the drive to serve as a compact interface between low-level motion commands and the higher current demanded by a stepper motor.
An internal chopper operates at 20 kHz, high enough to move switching noise outside most audible ranges while keeping current ripple low. The drive accepts step commands up to 2 MHz, allowing microstepped resolutions when paired with fine pulse generators. Each incoming pulse must be at least 250 ns wide, and the controller must hold the direction line stable for 50 µs before issuing the first step. This direction setup time helps prevent miscounts when reversing. Phase windings can draw up to 7.1 A peak during acceleration, while continuous operation is limited to 5 A rms. Logic I/O uses a 9-socket D-sub miniature connector, and the enabled output saturates at 0.5 V when sourcing 2 mA so downstream status circuits can detect a clear low state. These signal and current limits make the drive suitable for pulse-based motion systems that need predictable timing behavior.
An overvoltage fault trips if the bus rises to 83 Vdc, protecting the internal power stage during regeneration. When the motor is idle, the drive automatically cuts current by 50%, lowering heat dissipation and reducing unnecessary motor heating during dwell periods. Safe operation requires the chassis temperature to stay below 60 °C, so cabinet airflow must remove the generated heat. The aluminum housing measures 5 × 1.5 × 4.3 in and weighs 1 lb, which helps conserve panel space when several axes are installed in the same enclosure. Its compact body also makes side-by-side mounting more practical in dense control cabinets.
