5. Straight Keyed Shaft: Simplifies coupling installation and ensures consistent torque transmission.

6. Brushless Motor Technology: Low noise, no carbon brush wear, long service life, and reduced maintenance.

7. Fanless Cooling: Eliminates fan-related failures, lowers noise, and improves long-term reliability.

6. Application Scope

• Vertical feed axes of 400V-class CNC machine tools (lathes, milling machines, machining centers)

• High-voltage automation lines requiring vertical load holding

• Packaging, printing, and textile machinery with vertical motion axes

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

• CNC applications with long-distance wiring requirements

7. Installation Guidelines

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

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

3. Use dedicated shielded power, brake, and encoder cables; separate power and signal wiring to prevent EMI.

4. Maintain adequate clearance for natural heat dissipation; do not block the motor housing.

5. Handle carefully during installation to avoid impact, which could damage the encoder or brake components.

8. Maintenance Instructions

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

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

3. Sealed bearings are lubricated for life; no periodic greasing is required under normal conditions.

4. Periodically check encoder cable integrity and connector tightness.

5. Avoid prolonged overload or frequent rapid forward/reverse cycling beyond rated parameters.

6. Verify brake operation periodically to ensure reliable load holding.

9. Safety Precautions

1. Disconnect all 380–400V high voltage before maintenance; wait 15 minutes for capacitors to discharge to prevent electric shock.

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

3. Do not disassemble the motor, brake, or encoder; unauthorized disassembly voids the warranty and may damage precision components.

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

5. For vertical axis applications, confirm brake reliability before power-on to prevent load falling.

10. Troubleshooting

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

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

• Overheating: Inspect for prolonged overload, high ambient temperature, or insufficient ventilation.

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

• Brake failure/load slipping: Confirm 24 VDC brake power supply, brake wear, or parameter settings.
