7. Installation Guidelines

1. Install the motor on a rigid, flat and deformation-free mounting base to avoid resonance and mechanical stress.

2. Keep high precision alignment between motor taper shaft and coupling to prevent vibration, noise and premature bearing damage.

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

4. Reserve enough surrounding space for natural heat dissipation; do not cover or block the motor shell heat dissipation area.

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

8. Maintenance Instructions

1. Regularly inspect running status including abnormal noise, vibration and temperature rise.

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

3. Built-in bearings adopt sealed lifelong lubrication, no regular refueling maintenance required under normal working conditions.

4. Check encoder cable integrity, connector fastening and aging status at regular intervals.

5. Avoid long-term overload operation and frequent forward and reverse start-stop beyond allowable range.

9. Safety Precautions

1. Cut off all power supply before installation, wiring, disassembly and maintenance. Wait at least 15 minutes for internal capacitor discharge to prevent electric shock hazard.

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

3. This model has no holding brake; do not apply to vertical axis or suspended load which has falling risk without external mechanical locking device.

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

5. Do not use in environment with conductive dust, strong moisture condensation and chemical corrosion without special protection.

10. Troubleshooting

• Motor cannot start: Check three-phase power supply, wiring tightness, servo amplifier alarm code and enable signal.

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

• Motor overheating: Inspect long-term overload, ambient temperature over limit, poor ventilation and winding insulation deterioration.

• Positioning deviation and out of tolerance: Check encoder cable breakage, loose connector, servo parameter mismatch and mechanical transmission backlash.

• Unstable speed: Verify power supply voltage fluctuation, load mutation and encoder signal interference.
