7. Installation Guidelines

1. Mounting: Install the motor on a rigid, vibration-free surface using the flange mounting holes. Ensure the mounting surface is flat to avoid mechanical stress.

2. Shaft Alignment: Align the motor shaft with the load shaft precisely to prevent misalignment-induced vibration and wear.

3. Cabling: Use shielded cables for power and encoder connections to reduce electromagnetic interference (EMI). Follow FANUC’s wiring diagrams for proper connection.

4. Brake Wiring: Connect the 24VDC brake power supply correctly. The brake is released when 24VDC is applied and engaged when power is cut off.

5. Ventilation: Ensure adequate ventilation around the motor to prevent overheating. Do not block the motor’s heat dissipation areas.

8. Maintenance

1. Regular Inspection: Periodically check the motor for abnormal noise, vibration, or overheating. Inspect cables and connectors for damage or looseness.

2. Lubrication: The motor’s bearings are pre-lubricated and sealed for life under normal operating conditions. No regular lubrication is required.

3. Cleaning: Keep the motor clean and free of dust, debris, and moisture. Use a dry cloth to wipe the motor surface; avoid using water or harsh chemicals.

4. Encoder Care: The encoder is a precision component. Avoid impact or vibration to the encoder. Keep the encoder cable intact and properly connected.

5. Brake Check: Regularly test the brake’s holding torque to ensure it functions correctly, especially in safety-critical applications.

9. Safety Precautions

1. Electrical Safety: Disconnect all power supplies before performing installation, maintenance, or repair work on the motor. Wait at least 15 minutes for internal capacitors to discharge to avoid electric shock.

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

3. Environmental Safety: Do not use the motor in explosive, flammable, or corrosive environments unless it is specially modified for such conditions.

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

10. Troubleshooting

• Motor Fails to Start: Check power supply connections, brake release signal, and amplifier status. Verify no alarm codes are present in the servo system.

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

• Overheating: Verify ambient temperature is within range, ventilation is adequate, and load is not excessive. Check for motor winding insulation failure.

• Positioning Inaccuracy: Check encoder connection, cable integrity, and servo parameter settings. Verify no mechanical backlash in the transmission system.
