Product Features Medium Inertia Rotor: Balances dynamic response and load stability, suitable for frequent speed changes and variable loads. High-Resolution Absolute Encoder: Enables high-precision positioning without battery backup for absolute position memory. Robust Construction: Rigid housing and high-precision bearings ensure long life and low noise. IP54 Protection: Suitable for workshop environments with dust, oil mist, and splashing water. Compatibility: Fully compatible with FANUC Alpha i-B series servo amplifiers for direct replacement. 7. Installation Instructions Power Off: Disconnect all power before installation and wiring. Flange Mounting: Use four M8 bolts, tightened evenly to ensure flat mounting and concentricity. Coupling: Use a suitable coupling to connect the motor shaft to the load. Maintain coaxiality to avoid vibration and bearing damage. Shaft Load: Do not apply heavy impact or excessive radial/axial loads. Cabling: Use FANUC shielded power, encoder, and brake cables (if applicable). Route cables correctly, maintaining sufficient bending radii. Grounding: Properly ground the motor frame for electrical safety. 8. Operation Precautions Rated Limits: Do not exceed rated voltage, speed, or torque for extended periods to prevent overheating and demagnetization. No Brake: This model has no holding brake. Secure vertical loads externally when power is off. Environment: Avoid use in explosive, corrosive, or highly conductive dust environments. No Disassembly: Unauthorized disassembly of the motor or encoder voids the warranty. Abnormal Conditions: Stop operation immediately and cut power if abnormal noise, vibration, overheating, or servo alarms occur. 9. Maintenance and Storage Cleaning: Regularly remove dust and oil from the motor surface to maintain heat dissipation. Inspection: Periodically check mounting bolts, coupling tightness, and cable connections. Bearings: Factory-lubricated for life. Replace if abnormal noise occurs. Encoder: Check cable seals and connectors to maintain IP54 protection. Storage: Keep in a dry, clean, ventilated area (5°C to 35°C, ≤85% humidity, non-condensing). Use original packaging, avoid direct sunlight and heavy stacking. 10. Ordering Description Model Number: A06B-0147-B075.
