IV. Compatibility and Usage Notes
Driver Matching: Must be used with a Schneider Lexium 05 series (such as LXM05) 400V servo driver; cannot be directly connected to mains power.
Installation Notes: IP50 protection rating; avoid dust, oil, and liquid splashes during installation. The flange mounting holes are standard 70mm, compatible with most automation equipment.
Electrical Connections: Dual connector design; one is for power supply (high current), and the other is for encoder feedback (position signal). Connect according to Schneider Electric’s standard wiring diagram to avoid reverse connection and motor burnout.
Performance Characteristics: High speed (6000rpm rated, 8000rpm maximum), suitable for high-speed motion scenarios; Low inertia design, fast dynamic response, suitable for high-frequency motion machine such as SMT machines and component insertion machines; SinCos encoders support high-precision position control, with positioning accuracy down to the micron level.
