Product Description:

The 6410-012-C-H-N is a micro-stepping drive produced by Pacific Scientific for the 6410 Stepper Drives series. Designed for two-phase stepper motors in automated machinery, the unit translates high-speed pulse and direction commands from a controller into precisely timed phase currents, allowing repeatable indexing and positioning without mechanical gearing. By managing coil energy electronically, the drive provides compact motion control for pick-and-place stations, labeling heads, and indexing tables, and it supports smoother low-speed movement in applications that need quiet running and consistent incremental moves.

In operation, the drive uses a two-phase bipolar chopper topology that modulates coil voltage at a carrier of 20 kHz, reducing audible noise while keeping current ripple low. Programmable micro-stepping reaches a maximum resolution of 1/256, so one revolution can be divided into 51,200 discrete positions for finer motion control. Rated phase output is 5.0 A RMS, with short-term bursts up to 7.1 A peak during acceleration. A 9-contact female D-sub carries step, direction, and enable signals, while power enters through a PCD ELVH0310 header and motor phases exit through a PCD ELVH0510 plug. The housing mass is 1.0 lb, which keeps panel loading modest in compact enclosures.

The controller accepts supplies from 24 VDC to 75 VDC, allowing it to share a common bus with other low-voltage motion axes. Internally, it clocks incoming pulses at rates up to 2 MHz, so commanded speed is not limited by the input stage even when fine micro-stepping is selected. Thermal limits include a maximum chassis temperature of 60 °C, and recommended ambient operation is from 0 °C to 50 °C to avoid derating. When ambient temperature rises, internal sensors can trigger a fault shutdown before components exceed allowable operating temperature, which helps protect the drive and connected motor during extended duty cycles.
