• Industrial robots and automation equipment

• Precision positioning systems

• High-speed pick-and-place machines

• General industrial motion control

7. Installation Guidelines

1. Mounting: Use the flange holes to mount the motor on a rigid, flat, vibration-free surface. Avoid mechanical stress due to misalignment.

2. Shaft Alignment: Align the motor shaft and load shaft accurately to prevent vibration, noise, and premature bearing wear.

3. Cabling: Use shielded cables for power and encoder wiring to reduce EMI. Separate power cables from signal cables.

4. Ventilation: Ensure free airflow around the motor. Do not block heat-dissipation areas.

5. Encoder Handling: The encoder is a precision component; avoid shocks and excessive vibration during installation and operation.

8. Maintenance

1. Regular Inspection: Check for unusual noise, vibration, or overheating. Inspect cables and connectors for damage or looseness.

2. Cleaning: Keep the motor surface clean and free of dust, chips, and moisture. Use a dry cloth; avoid water and harsh chemicals.

3. Bearing Maintenance: Bearings are maintenance-free under normal use. If abnormal noise occurs, contact FANUC or an authorized service provider.

4. Encoder Care: Keep the encoder cable intact and properly connected. Avoid impact to the encoder cover.

9. Safety Precautions

1. Electrical Safety: Disconnect all power before installation, maintenance, or repair. Wait at least 15 minutes for capacitors to discharge to prevent electric shock.

2. Mechanical Safety: Do not touch the rotating shaft or moving parts during operation. Ensure the load is securely fixed before starting.

3. Environmental Safety: Do not use in explosive, flammable, or corrosive atmospheres unless specially modified.

4. Warranty Note: Warranty does not cover damage caused by liquids, improper installation, misuse, or unauthorized modification.

10. Troubleshooting

• Motor Does Not Run: Check power supply, wiring connections, servo amplifier status, and alarm codes.

• Abnormal Noise/Vibration: Inspect shaft alignment, mounting rigidity, and bearing condition. Check for loose components.

• Overheating: Verify ambient temperature, ventilation, and load conditions. Check for winding insulation failure.

• Positioning Error: Check encoder connection, cable integrity, and servo parameter settings. Inspect mechanical backlash.

11. Warranty & Support

• Warranty Period: 1 year from the date of shipment.

• Repair Service: Repair is available. Contact FANUC or an authorized service provider.

• Technical Support: For technical questions, contact FANUC technical support or local distributors.
