Product Short Description
Product Name: 6440 series microstepping drive and indexer with AC input
Product Introduction: An AC-powered member of the 6400 stepper family that integrates power supply rectification, microstepping amplifier and mnemonic-program indexer for medium-power 2-phase steppers.
Technical Specifications:
- Input: 120/240 VAC ±10 %/-15 %, 50/60 Hz
Description
- Output current: 0.625–5.0 A rms adjustable, bipolar chopper 20 kHz
- Serial: RS-232 or RS-422/RS-485 at 9600 bps
- Programming: Mnemonic language, 1792 bytes NV memory
- Fuse: 5 A Slo-Blo 250 VAC
- Operating temp: 0–50 °C, storage -40–70 °C, 10–90 % RH
- Weight: ~6 lb (2.7 kg)
- Options on 6440-001-K-N: K = AC input configuration, N = no cover, N = no heatsink
Functional Features: AC-line operation without external DC supply, standalone indexing, PID-free electronic damping, multi-unit RS-485 networking, configurable microstep resolution.
Application Scenarios: Semiconductor handling stages, vacuum gate drives, packaging cut-off knives, standalone rotary indexers on legacy machines.
Working Principle: Internal rectifier produces DC bus, chopper regulates phase current from step/dir or internal program, pendulum or linear actuator motion is sequenced by mnemonic code stored in NVRAM and triggered through serial or discrete I/O.
Installation Requirements: Ground AC chassis properly, provide fusing on AC feed, mount with bottom clearance for convection, set current dip switches before applying AC.
Usage Notes: AC inlet is live even when motor idle; 6440 is heavier and louder than DC 6410; confirm K-suffix means AC line version before wiring.
