• High-inertia rotor: Ensures stable operation under large load fluctuations and frequent start/stop.

• Multiple encoder options: Absolute (A64) or incremental (I64) for diverse control needs.

• Optional holding brake: Ensures safety for vertical/suspended loads during power loss.

• IP65 sealing: Protects against dust, oil mist, and coolant splash for harsh environments.

• Fanless cooling: Reduces maintenance and failure risk.

• Amplifier compatibility: Fully compatible with FANUC Alpha i-B series servo amplifiers.

7. Installation Instructions

1. Power Off: Disconnect all motor/driver power before installation, wiring, or maintenance.

2. Mounting: Flange-mount horizontally (preferred) or vertically; tighten four bolts evenly to ensure flatness and concentricity.

3. Coupling: Use a heavy-duty precision coupling; maintain shaft coaxiality to avoid vibration, noise, or bearing damage.

4. Shaft Handling: Do not hammer the shaft end; avoid excessive radial/axial loads.

5. Wiring: Use FANUC shielded power/encoder cables; avoid high-voltage parallel runs; maintain minimum bending radius.

6. Connectors: Secure all connectors; ensure seal integrity to preserve IP65 rating.

7. Grounding: Earth the motor shell reliably to prevent leakage and electromagnetic interference.

8. Operation Precautions

• Do not exceed rated voltage, speed, or torque (risk of overheating, demagnetization, or insulation failure).

• The built-in brake is for holding only; do not use for dynamic stopping. Test brake performance regularly for vertical axes.

• Avoid explosive, corrosive, or conductive dust environments.

• Do not disassemble the motor/encoder (voids warranty and damages sealing).

• Stop immediately if abnormal noise, vibration, housing temperature >80°C, or servo alarms occur.

• Minimize frequent jogging to reduce current surge and thermal stress.

9. Maintenance and Storage Requirements

• Cleaning: Regularly remove dust/oil from the housing for effective heat dissipation.

• Inspections: Check mounting bolts, coupling tightness, and connector seals periodically.

• Bearings: Factory-lubricated (no scheduled oiling); replace if noise/vibration arises.

• Seals: Verify shaft/connector seals to maintain IP65 protection.

• Storage: Store indoors (5°C–35°C, ≤85% humidity, non-condensing) in original packaging; avoid sunlight, moisture, or heavy loads.
