Installation Instructions

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

• Keep the mounting surface clean, flat, and free of debris or deformation.

• Align the straight shaft with the load; use a flexible coupling to compensate for minor misalignment.

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

• Reserve sufficient clearance around the motor and cooling fan for unobstructed airflow and maintenance access; do not block fan vents.

• Ensure the cooling fan is connected to a dedicated power supply for continuous operation during motor use.

• For vertical axis installation, verify brake alignment and wiring to ensure reliable holding performance.

Wiring Requirements

• Perform all wiring with the power disconnected; 400V poses an electric shock risk.

• Use FANUC-approved power, encoder, fan, brake, and ground cables.

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

• Route encoder signal cables separately from main power cables to avoid electromagnetic interference (EMI).

• Connect the cooling fan wires to a dedicated power supply; ensure correct polarity to avoid fan damage.

• Connect the 24V DC brake wires to a dedicated power supply; confirm correct voltage and polarity for proper brake engagement and release.

• Ensure all wiring terminals are tightly fastened with good insulation performance (≥100 MΩ at 500 VDC).

• Follow FANUC’s official standard wiring specifications for servo motor connections.

Working Environment

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

• Altitude: ≤1000 m (derate output above 1000 m)

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

• Vibration: ≤5G (avoid long-term strong mechanical vibration and impact)

Operation Guidelines

• Operate the motor strictly within rated voltage, torque, and speed limits; do not overload continuously.

• Perform a no-load trial run after installation to check for abnormal noise, vibration, or excessive temperature rise.

• Monitor the motor housing, cooling fan, and brake temperature during operation; ensure surface temperature ≤100 °C.

• Avoid excessive start-stop cycles to prevent overheating and mechanical wear.

• Set servo amplifier parameters correctly based on the motor model and actual load conditions.

• Ensure the cooling fan is operational before motor startup; do not run the motor with the fan disabled.

• Verify brake release before motor operation and brake engagement after motor stop for vertical axis safety.

Maintenance Instructions

• Regularly cut off the power and clean dust, oil stains, and coolant from the motor housing, cooling fan, and brake assembly.

• Periodically check the mounting bolts, coupling tightness, encoder connectors, fan wiring, and brake wiring for security.

• Listen for abnormal bearing noise or fan vibration and inspect for excessive motor vibration during operation.

• Regularly use the CNC system’s diagnostic function to check encoder signal quality and positioning stability.

• Inspect the cooling fan blades for damage or debris buildup periodically to maintain airflow efficiency.

• Test the brake function regularly to ensure reliable engagement and release; replace brake components if performance degrades.

• Do not disassemble the motor, fan, brake, or encoder privately; this will damage precision components and void the warranty.

Safety Precautions

• Only qualified personnel trained in 400V systems may install, wire, or maintain the motor.

• Disconnect all power before maintenance or wiring work; wait for capacitors to fully discharge.

• Never touch the rotating shaft, cooling fan blades, brake components, or live electrical components during motor operation.

• Ensure reliable grounding to prevent electric shock and reduce EMI.

• Do not modify the motor’s internal structure, fan circuit, brake circuit, or encoder configuration arbitrarily.

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

• Ensure the cooling fan and brake are fully functional before motor operation to avoid overheating, free fall, and damage.
