Key Hardware Features
- Patented Digital Damping: Unlike standard drives, the 6410 uses an electronic feedback loop to sense motor back-EMF, providing active damping that allows the motor to utilize its full torque-speed curve without stalling at resonance points.
- Microstepping Precision: The drive can divide a standard 1.8° step into 125 microsteps, resulting in incredibly smooth low-speed movement and higher positioning resolution.
- Selectable Current Waveforms: Users can adjust the current waveform to match the specific inductance and resistance of various stepper motors, optimizing torque output and reducing motor heating.
- Modular “N-N-N” Configuration: The suffix denotes a standard unit without specialized factory options for cooling or connectors, designed for panel mounting within a standard industrial enclosure.
Product Datasheet Summary
- Power Stages: Employs high-efficiency MOSFET technology to minimize heat dissipation within the drive housing.
- Logic Compatibility: The step and direction inputs are optically isolated and compatible with 5V to 24V logic signals, making it easy to interface with PLCs and motion controllers.
- Dynamic Smoothing: Includes a user-selectable “Step Filter” that smooths out pulse bursts from lower-quality indexers to prevent motor jerk.
- Thermal Management: Features an internal heatsink. While the 6410-009 is naturally aspirated, it relies on the cabinet’s ambient airflow to maintain an operating temperature below 50∘C.
Country of Origin
The Pacific Scientific 6410-009-N-N-N was designed and manufactured in the United States of America (USA). Following the acquisition of Pacific Scientific by Danaher and subsequently Kollmorgen, these drives continue to be recognized as staples of American industrial motion control engineering.
Application Areas
The 6410-009 is used in applications requiring high torque at low speeds and precise open-loop positioning:
- Packaging Machinery: Labeling, filling, and capping stations where repeatability is critical.
- Medical Equipment: Automated liquid handling and laboratory diagnostic carousels.
- Semiconductor Manufacturing: Wafer handling and precision stages that must avoid mechanical vibrations.
- Printing and Textiles: Feeding mechanisms that require smooth, continuous motion to prevent material tearing.

Product Usage Instructions
- Mounting:
- Install the drive vertically on a flat, unpainted metal surface to maximize heat transfer. Leave at least 2 inches of clearance above and below the unit.
- Wiring the Motor:
- Connect the two-phase stepper motor to the 4-pin motor terminal. Ensure the A/A! and B/B! phases are correctly identified to prevent reverse rotation or vibration.
- Setting the Current:
- Before applying power, set the internal DIP switches to match the motor’s rated current. Operating the drive at a current higher than the motor rating will lead to permanent thermal damage to the motor windings.
- Signal Interface:
- Connect the Step and Direction lines from your indexer or PLC. If using 24V logic, ensure the appropriate current-limiting resistors are used as per the 6400 series manual to protect the optoisolators.
- Power-Up:
- Apply 120 VAC to the L and N terminals. The “Power” LED should illuminate. If the “Fault” LED lights up, immediately disconnect power and check for short circuits in the motor wiring.
