Product Description:

The 6410-008-N-N-N is a compact microstepping drive manufactured by Pacific Scientific within the 6410 Stepper Drives series. Designed for panel-mounted motion axes, the drive accepts step and direction signals from indexers or PLCs and modulates winding current to a two-phase motor. By integrating chopper regulation and selectable current limits, it provides accurate torque control for industrial automation tasks such as pick-and-place heads, small gantries, and labeling systems.

In operation, the drive uses a two-phase bipolar, chopper-regulated output stage that pulses the motor windings at 20 kHz to limit current while minimizing audible noise. Phase current can be adjusted from 0.625 A up to 5.0 A, allowing the same unit to run a wide range of compatible stepper motors. The temperature alarm is referenced to 60 °C on the chassis, so enclosure airflow should keep the housing below the derating threshold. Logic inputs are optically isolated; the step channel requires 5.5 mA, while the direction channel activates with 3.0 mA and tolerates 5 V of reverse bias without damage. These input thresholds let the 6410 drive connect to 5 V TTL, 12 V, or 24 V sourcing controllers without level shifting.

On the motion side, the drive’s step accumulator accepts pulses up to 2 MHz, while an internal digital filter limits effective command bandwidth to 500 kHz to suppress aliasing at lower feed rates. With a standard 1.8° motor, full-step resolution is 200 steps per revolution, and the available pulse rate supports fine positioning at high shaft speeds. The minimum programmable velocity ramp is 50 ms, which suits rapid point-to-point indexing without excessive jerk. All power enters through the keyed PCD ELVH0310 plug, motor phases exit on the PCD ELVH0510 header, and control lines terminate on a 9-contact female D connector. The aluminum enclosure weighs 1.0 lb, allowing dense multi-axis mounting inside control cabinets.
