• Packaging, printing, and conveying machinery

• Horizontal axes and non-vertical loads (no brake)

8. Installation Instructions

1. Mounting Surface

   Install on a rigid, flat, and vibration-free base to avoid resonance and mechanical stress.
2. Shaft Alignment

   Align motor shaft and load shaft precisely to prevent excessive vibration, noise, and bearing damage.
3. Cabling

   Use shielded servo power cables and encoder cables. Separate power and signal wiring to minimize electromagnetic interference.
4. Heat Dissipation

   Maintain clear space around the motor housing for natural convection; do not cover cooling surfaces.
5. Handling

   Avoid heavy impact, dropping, or compression on the motor body and encoder cover.

9. Maintenance

1. Regular Inspection

   Check for unusual noise, vibration, or overheating during operation.
2. Cleaning

   Keep motor surface free of dust, metal chips, and oil.
3. Bearings

   Sealed bearings are pre-lubricated for life; no routine greasing required.
4. Encoder & Cables

   Inspect encoder cables and connectors periodically for damage or looseness.
5. Operation Limits

   Avoid continuous overload and excessive frequent start–stop cycles.

10. Safety Precautions

1. Electrical Safety

   Disconnect all power before wiring or maintenance. Wait at least 15 minutes for capacitor discharge to prevent electric shock.
2. Moving Parts

   Do not touch rotating shaft or moving components during operation.
3. No Brake Warning

   This model has no holding brake. Do not use for vertical axes or suspended loads without additional mechanical safety devices.
4. Do Not Disassemble

   Unauthorized disassembly of motor or encoder will void warranty and may damage precision components.
5. Environmental Protection

   Do not use in environments with conductive dust, heavy condensation, or chemical corrosion without proper protection.

11. Troubleshooting

• Motor does not start

  Check 3-phase power, wiring connections, amplifier alarms, and servo enable signals.
• Abnormal noise or vibration

  Check mounting rigidity, shaft alignment, bearing condition, and mechanical load jamming.
• Motor overheating

  Check for overload, high ambient temperature, blocked ventilation, or insulation deterioration.
• Positioning error

  Check encoder cable damage, loose connectors, parameter mismatch, or mechanical backlash.
• Unstable speed

  Check power supply fluctuation, sudden load changes, or encoder signal interference.
