5. Key Features

1. Integrated 24 VDC Holding Brake: Maintains position when power is off; enhances safety for vertical or suspended loads.

2. High-Resolution Encoder: B128iA (128K) incremental encoder provides precise position/speed feedback for high-precision motion control.

3. IP67 Sealed Construction: Dust-tight and protected against water immersion; suitable for harsh industrial environments.

4. Compact High Torque: Delivers 3.5 N·m rated torque in a compact frame; ideal for space-constrained, high power density applications.

5. Maintenance-Free Operation: Brushless design eliminates brush wear; sealed, pre-lubricated bearings for life under normal conditions.

6. Applications

• CNC machine tools (milling, lathes, machining centers)

• Industrial robots and automation equipment

• Precision positioning systems

• High-speed pick-and-place machines

• General industrial motion control (especially vertical-axis applications)

7. Installation Guidelines

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

2. Shaft Alignment: Accurately align motor and load shafts to prevent vibration, noise, and premature bearing wear.

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

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

5. Encoder & Brake Handling: The encoder is a precision component—avoid shocks. Connect the brake to a regulated 24 VDC supply.

8. Maintenance

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

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

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

4. Encoder & Brake Care: Keep encoder cables intact. Periodically test brake operation to ensure proper holding force.

9. Safety Precautions

1. Electrical Safety: Disconnect all power before installation/maintenance. Wait ≥15 minutes for capacitors to discharge to prevent electric shock.

2. Mechanical Safety: Do not touch rotating shafts during operation. Secure loads before starting; the brake is for holding, not stopping motion.

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

4. Warranty Note: Warranty excludes damage from liquids, improper installation, misuse, or unauthorized modification.

10. Troubleshooting

• Motor Does Not Run: Check power supply, wiring, servo amplifier status, and alarm codes. Verify brake release (24 VDC applied).

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

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

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

• Brake Failure: Test 24 VDC supply; inspect brake wiring and coil resistance.

11. Warranty & Support

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

• Repair Service: Available via FANUC or authorized service providers.

• Technical Support: Contact FANUC technical support or local distributors for technical questions.
