7. Installation Guidelines

1. Mount the motor on a rigid, flat and non-deformable base to avoid mechanical stress and resonance.

2. Keep precise alignment between motor shaft and load shaft to reduce vibration, noise and premature bearing wear.

3. Use shielded dedicated servo power cable and encoder cable; separate power wiring and signal wiring to reduce electromagnetic interference.

4. Reserve enough space around the motor for heat dissipation; do not block the heat dissipation area of the motor housing.

5. Avoid strong impact, dropping and extrusion on the motor body and encoder rear cover during handling and installation.

8. Maintenance Instructions

1. Regularly check the motor operating status including abnormal noise, vibration and temperature rise.

2. Keep the motor surface clean, remove dust, metal chips and oil stains periodically.

3. The built-in sealed bearings adopt lifetime lubrication, no regular refueling is required under normal working conditions.

4. Inspect encoder cable integrity, connector tightness and aging status regularly.

5. Avoid long-term overload operation and frequent start-stop beyond the allowable load range.

9. Safety Precautions

1. Disconnect all power supply before installation, wiring and maintenance. Wait at least 15 minutes for internal capacitors to discharge to prevent electric shock.

2. Do not touch the rotating shaft and moving parts during motor operation.

3. This model is not equipped with a holding brake; it is prohibited to use it for vertical axes or suspended loads with falling risks without additional mechanical locking devices.

4. Do not disassemble the motor and encoder privately; unauthorized disassembly will void the warranty and damage assembly precision.

5. Do not use the motor in environments with conductive dust, heavy condensation and chemical corrosion without special protection.

10. Troubleshooting

• Motor fails to start: Check three-phase power supply, wiring tightness, servo amplifier alarm codes and enable signals.

• Abnormal noise and vibration: Check mounting rigidity, shaft alignment, bearing aging and mechanical load jamming.

• Motor overheating: Inspect overload operation, excessive ambient temperature, poor ventilation and winding insulation aging.

• Positioning deviation: Check encoder cable damage, loose connectors, mismatched servo parameters and mechanical transmission backlash.

• Unstable speed: Check power supply voltage fluctuation, sudden load change and encoder signal interference.
