7. Installation Instructions

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

2. Mounting: Flange-mount horizontally/vertically; tighten four bolts evenly to ensure flatness and concentricity.

3. Coupling: Use a 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 bending radius.

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

7. Grounding: Earth the motor shell reliably to prevent leakage and 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, >80°C housing temperature, 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 IP protection.

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