Installation Instructions

• Mount the motor on a rigid, flat base to avoid resonance and shaft misalignment.

• Keep the mounting surface clean, flat, and free of debris or burrs to ensure full contact.

• Align the motor shaft with the driven load to maintain coaxiality; use a flexible coupling to compensate for minor misalignments.

• Tighten flange bolts evenly to the specified torque to prevent housing deformation.

• Reserve 50 mm of clearance around the motor for ventilation, wiring, and maintenance.

• Do not block the motor’s heat dissipation areas to avoid overheating.

Wiring Requirements

• Perform all wiring with power disconnected to prevent electric shock.

• Use FANUC‑approved power, encoder, and ground cables matching the motor’s specifications.

• Connect three‑phase power (U/V/W) and protective earth (PE) terminals securely; ensure reliable grounding (≤4 Ω).

• Route encoder cables at least 10 cm away from power cables to minimize electromagnetic interference.

• Follow FANUC’s official wiring diagrams to avoid incorrect connections.

• Torque all terminal screws to the specified torque to prevent loose connections.

Working Environment

• Operating Temperature: 0°C to +40°C.

• Storage Temperature: −20°C to +60°C (non‑condensing).

• Humidity: ≤80% RH (non‑condensing).

• Altitude: ≤1000 m (derate output 1% per 100 m above 1000 m).

• Atmosphere: Free of corrosive gases, explosive dust, or excessive oil mist.

• Vibration/Shock: Avoid prolonged exposure to strong mechanical vibration or impact.

Maintenance Instructions

• Every 3 Months: Disconnect power; clean dust and oil from the motor housing with a dry cloth.

• Every 6 Months: Check mounting bolts, coupling tightness, and encoder connectors for security.

• Every 12 Months: Inspect bearings for abnormal noise or vibration; replace bearings if noise occurs.

• Quarterly: Use CNC diagnostic tools to verify encoder signal quality and positioning stability.

• Prohibition: Do not disassemble the motor or encoder without authorization; unauthorized disassembly voids the warranty.

• Storage: When not in use, store the motor in a dry, temperature‑controlled environment.

Safety Precautions

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

• Disconnect all power before maintenance; wait 5 minutes for internal capacitors to discharge.

• Never touch the rotating shaft or live electrical components during operation.

• Ensure reliable grounding to prevent electric shock and reduce electromagnetic interference.

• Do not modify the motor’s internal structure or encoder configuration arbitrarily.

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