Product Description:

The 6415-001-N-N-K is a microstep drive from Pacific Scientific that belongs to the 6415 Microstep Drives series. It converts low-level command signals into precisely timed current pulses that position hybrid stepper motors in automated material-handling, gantry, and indexing equipment. By closing the control loop on pulse count rather than rotor feedback, the unit simplifies wiring and is often mounted inside distributed machine panels where compact motion modules are required.

The command interface accepts differential step and direction inputs or a ±10 V analog signal. A high input impedance of 20 kΩ prevents the drive from loading PLC or motion-card outputs, while the positive limit of +10 Vdc and the negative limit of -10 Vdc set the full-scale speed command range. Internally, a pulse-width-modulated current loop operates at 20 kHz, pushing switching noise above audible frequencies and reducing motor hum. The digital translator can process incoming pulse streams at up to 500 kHz, allowing very small microstep angles without losing command data during rapid indexing. A connector kit is supplied, and the housing ships without a cover or an added heat sink so that designers can integrate the chassis directly against cabinet plates or external convection fins.

The power stage delivers a peak phase current of 7.1 A for acceleration demands and an RMS value of 5.0 A during continuous moves, matching the thermal limits of NEMA sizes 23 and 34 motors. It operates from a DC bus between 24 Vdc and 75 Vdc, enabling use on 48-volt mobile platforms as well as rectified 60-volt industrial supplies. With a maximum operating temperature of 50 °C and a 60 °C chassis limit, the open-frame layout relies on airflow inside the enclosure. Storage can span -55 °C to +70 °C without component damage.
