• Packaging, printing, textile machinery, and general industrial automation equipment

• Servo systems requiring long-distance wiring with low current loss

• High-speed, high-precision motion applications without vertical load holding requirements

7. Installation Guidelines

1. Mount on a rigid, flat base to avoid resonance and mechanical deformation.

2. Ensure precise coaxial alignment between motor and load shafts to reduce vibration and bearing wear.

3. Use dedicated shielded high-voltage power and encoder cables; separate power and signal wiring to minimize EMI.

4. Reserve sufficient space for natural heat dissipation; do not block the motor housing.

5. Avoid impact, dropping, or extrusion during handling/install to protect the motor and encoder.

8. Maintenance Instructions

1. Regularly inspect for abnormal noise, vibration, or overheating.

2. Keep the motor surface clean of dust, metal chips, and oil contamination.

3. Sealed bearings have lifetime lubrication; no regular refueling needed under normal conditions.

4. Periodically check encoder cable integrity and connector tightness.

5. Avoid long-term overload or frequent forward/reverse start-stop beyond load limits.

9. Safety Precautions

1. Cut off all 380–400V high voltage power before work; wait 15 minutes for capacitor discharge to prevent electric shock.

2. Do not touch rotating shafts or moving parts during operation.

3. Do not disassemble the motor or encoder privately; unauthorized disassembly voids the warranty and damages precision.

4. Avoid use in conductive dust, heavy condensation, or corrosive environments without protection.

10. Troubleshooting

• Motor fails to start: Check 3-phase 400V power, wiring tightness, servo amplifier alarms, and enable signal.

• Abnormal noise/vibration: Verify mounting rigidity, coupling alignment, bearing condition, and load jamming.

• Overheating: Inspect for long-term overload, high ambient temperature, or poor ventilation.

• Positioning deviation: Check encoder cable damage, loose connectors, parameter mismatch, or mechanical backlash.

• Unstable speed: Confirm voltage fluctuations, sudden load changes, or encoder signal interference.
