6. Installation Instructions

Mechanical Installation

1. Mount the motor on a rigid, flat, and vibration‑free base to avoid resonance and misalignment.

2. Ensure the mounting surface is clean, flat, and free of debris.

3. Align the motor shaft with the driven load (e.g., ballscrew, gearbox) within specified tolerance; use a flexible coupling to compensate for minor misalignment.

4. Tighten mounting bolts evenly to the recommended torque value to prevent distortion.

5. Allow sufficient clearance around the motor for airflow, heat dissipation, and maintenance access.

Electrical Wiring

1. Isolate and lock out power before starting wiring work.

2. Use only FANUC‑approved cables: power cable, encoder cable, and ground cable.

3. Connect the three‑phase power lines (U, V, W) and protective earth (PE) securely.

4. Route the encoder cable separately from power cables to avoid electromagnetic interference; maintain minimum separation distance as specified.

5. Verify all connections are tight and insulated; check for proper grounding to prevent electric shock and noise.

6. Follow the wiring diagram provided in the FANUC servo amplifier and motor manual.

7. Operating Environment

• Ambient Temperature: 0 °C to +40 °C (operation); −20 °C to +60 °C (storage, non‑condensing)

• Humidity: 5 % to 95 % RH (non‑condensing)

• Altitude: ≤1000 m above sea level (derate above 1000 m)

• Atmosphere: Free from corrosive gases, explosive dust, and excessive oil mist

• Vibration: ≤0.5 g (continuous); ≤1 g (intermittent)

8. Operation Guidelines

1. Run the motor within the rated voltage, current, torque, and speed limits; avoid continuous overload.

2. Perform a no‑load test run after installation to check for abnormal noise, vibration, or temperature rise.

3. Monitor motor temperature during operation; the housing surface temperature should not exceed 100 °C.

4. Avoid frequent start‑stop cycles beyond the motor’s designed capability to prevent overheating and mechanical wear.

5. Ensure the servo amplifier parameters are correctly set to match the motor model and load conditions.

9. Maintenance and Inspection

Regular Inspection (Monthly/Quarterly)

• Check motor housing for dirt, oil, or coolant buildup; clean if necessary (power off first).

• Verify mounting bolts and coupling tightness.

• Check encoder cable connectors for damage, looseness, or corrosion.

• Listen for abnormal bearing noise during operation; check for excessive vibration.

• Confirm the motor runs at normal temperature and without unusual odor.

Periodic Maintenance (Every 6–12 Months)

• Inspect bearing grease condition; re‑grease or replace bearings if noise or roughness occurs.

• Check shaft key and keyway for wear or deformation.

• Verify encoder signal quality via CNC diagnostic functions.

• Clean cooling fins and ventilation paths if applicable.

• Perform a full performance test under load to confirm torque and speed accuracy.

Lubrication

• Bearings: Sealed, lifetime‑lubricated type under normal use; re‑lubricate only if operating in heavy‑dust or high‑humidity environments (use FANUC‑specified grease).

10. Troubleshooting (Common Issues)

• Motor fails to start: Check power supply, wiring connections, servo amplifier enable signal, and CNC alarm codes.

• Abnormal noise/vibration: Inspect bearing condition, shaft alignment, coupling tightness, and mounting rigidity.

• Excessive temperature rise: Check for overload, blocked ventilation, incorrect parameter settings, or phase imbalance.

• Positioning error or drift: Verify encoder connection, cable shielding, grounding, and encoder resolution settings.

• Servo alarm (overcurrent/overvoltage): Check load condition, wiring, power supply stability, and amplifier‑motor compatibility.

11. Safety Precautions

• Only qualified personnel should install, wire, maintain, or repair the motor.

• Disconnect and lock out all power sources before performing any work on the motor or wiring.

• Never touch rotating parts or live electrical components during operation.

• Ensure proper grounding to prevent electric shock and reduce electromagnetic noise.

• Do not modify or disassemble the motor or encoder; this will void the warranty and may cause malfunction or injury.

• Keep the motor and cables away from flammable materials and heat sources.
