• Vertical lifting & positioning mechanisms of high-voltage automation production lines

• Packaging, printing, textile special servo vertical motion equipment

• Medium-load precision motion systems requiring power-off load protection

• Long-wiring CNC servo feeding applications

7. Installation Requirements

1. Install on rigid flat base, avoid resonance and mechanical deformation

2. Strict coaxial alignment between motor shaft and load shaft, reduce vibration and bearing wear

3. Use dedicated shielded servo power cable, brake cable and encoder signal cable; separate strong & weak electricity wiring to avoid EMI interference

4. Keep enough heat dissipation space, do not block motor shell

5. Handle gently, avoid impact and drop to protect internal encoder and brake components

8. Daily Maintenance

1. Regular check abnormal noise, vibration and overheating status

2. Keep motor surface clean from iron dust, chips and oil pollution

3. Sealed bearings lifelong lubrication, no regular oil filling required

4. Inspect encoder connector, brake wire harness integrity and fastening status periodically

5. Prohibit long-time overload and frequent frequent forward-reverse start-stop beyond rated parameters

9. Safety Regulations

1. Cut off all 400V high-voltage power supply before maintenance; wait 15 minutes for servo drive capacitor discharge to avoid electric shock

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

3. Do not disassemble motor shell, brake and encoder privately; unauthorized disassembly invalidates warranty and damages precision parts

4. Avoid use in conductive dust, heavy condensation and corrosive environment without additional protection

5. Vertical axis must confirm brake reliability before power-on debugging to prevent load falling

10. Common Troubleshooting

• Motor cannot start: Check 3-phase 400V power supply, wiring connection, servo alarm code and axis enable signal

• Abnormal noise & vibration: Check mounting rigidity, coupling concentricity, bearing damage and load jamming

• Motor overheating: Caused by long overload, high ambient temperature or poor heat dissipation

• Position deviation: Encoder cable damage, loose connector, parameter mismatch or mechanical backlash

• Brake failure & load slipping: DC24V brake power abnormality, brake wear or brake parameter mismatch
