PACIFIC SCIENTIFIC 6410-001-N-N-N

Product Short Description

Product Name: 6410 Series Stepper Motor Drive

Product Introduction:

The PACIFIC SCIENTIFIC 6410-001-N-N-N is a two-phase bipolar, chopper current-regulated stepper motor drive. It converts step and direction inputs into motor winding currents to control a two-phase stepper motor. The drive offers microstepping and mid-band instability compensation for high resolution and smooth operation across low speed and mid-band resonance regions.

Description

Technical Specifications:

Manufacturer: Pacific Scientific (now part of Kollmorgen)
Product: 6410 Stepper Drive
Input Power Supply: 24-75 V DC @ 5.0 A
Rated Drive Current (Motor Phase Current): Selectable from 0.625 A to 5.0 A RMS
Chopper Frequency: 20 kHz nominal
Step Size: Switch-selectable from full step to 1/250 microstep (1/256 supported per manual)

Structural & Functional Features:

Bipolar Chopper Drive: Patented 4-phase PWM chopping at 20 kHz for high back EMF rejection with low chopping ripple
Digital Electronic Damping: Eliminates torque loss and motor stalling in mid-speed regions
Short Circuit Protection: Disables drive on motor output short circuit
MOSFET Power Devices: Eliminate acoustical noise
Optically Isolated Signal Interface: Enhances noise immunity
Enable Sense: Allows polarity reversal via jumper J6 5-6

Working Principle:

The drive receives step and direction pulses, then regulates the phase current to the motor windings via a 20 kHz bipolar chopper. Microstepping divides each full step into smaller increments (up to 1/250) for smooth, high-resolution motion. Digital electronic damping compensates for mid-band resonance instability inherent in open-loop stepper systems.

Application Scenarios:

X-Y tables and slides
Packaging machinery
Robotics
Specialty machinery
Index feed of material
Labeling machines

Installation Requirements & Precautions:

Mounting: Bookcase style to a cooling plate (aluminum plate or heatsink) with sufficient thickness to maintain chassis below 60°C, using two M4 or 6-32 screws
J3 Motor Connections: Connect to two-phase stepper motor windings
J2 Power Connector: 24-75 V DC @ 5.0 A
J1 Signal Interface: Optically isolated step/direction/enable inputs
DIP Switches: Set motor current (S1) and step size
Jumper J6: Configure Idle Current Reduction delay and Enable Sense polarity
Avoid customer modification, physical mishandling, or miswiring—these void the warranty
