3. Safety Precautions

• High Voltage: Disconnect power before installation or maintenance. Wait 10 minutes for capacitor discharge.

• Grounding: Connect the motor’s ground terminal to a reliable earth (resistance ≤4 Ω).

• Mechanical Load: Do not apply excessive radial/axial loads to the shaft.

• Rotating Parts: Keep hands and tools clear during operation.

• Brake Use: The holding brake is for static holding only, not dynamic stopping.

4. Installation

4.1 Mechanical

1. Mount on a rigid, flat surface.

2. Tighten mounting bolts (M10) to 45–50 N·m.

3. Align shaft coupling within 0.1 mm (radial) and 0.5° (angular).

4. Ensure sufficient ventilation (50 mm clearance around the motor).

4.2 Electrical

1. Power Wiring: Use shielded cables (2.5–4 mm²). Connect U/V/W/PE to corresponding terminals.

2. Encoder Wiring: Use FANUC-specified shielded cable. Secure the connector tightly.

3. Brake Wiring: Connect 24 V DC (±10%) to BRK+/BRK– (correct polarity).

5. Operation

• Speed Range: 0–3,600 min⁻¹ (avoid continuous operation above 3,000 min⁻¹).

• Torque Range: 0–9 N·m (continuous); up to 56 N·m (30 seconds max).

• Startup: Jog at low speed (100–500 min⁻¹) to check for smooth rotation and no abnormal noise.

• Monitor: During operation, monitor current, temperature, and vibration via the servo driver.

6. Maintenance

6.1 Monthly

• Inspect for damage, oil leaks, or loose connections.

• Clean the motor exterior with a dry cloth.

• Check for abnormal noise or vibration.

6.2 Every 6 Months

• Verify encoder and brake functions.

• Measure insulation resistance (≥1 MΩ at 500 V DC).

• Check bearing condition (no unusual noise).

6.3 Storage

• Store in a dry place (-20°C to +60°C, ≤60% humidity).

• Rotate the shaft 90° every 3 months to prevent bearing seizure.

7. Troubleshooting

• Overcurrent: Check for short circuits, ground faults, or excessive load.

• Encoder Error: Inspect cable/connector for damage or loose connection.

• Overheating: Reduce load, improve ventilation, or check for bearing wear.

• Abnormal Noise: Check bearing wear, shaft misalignment, or foreign matter.
