2.2 Wiring Diagram
Proper wiring is critical for safe and correct operation. Refer to the diagram below for connecting the inverter to the spindle motor and power supply.
2.3 Inverter Settings
The inverter (VFD) controls the spindle motor's speed and operation. The factory default setting for YL Inverters is typically 400Hz, which is suitable for this spindle motor. If adjustments are needed, use the following parameters:
| Parameter | Setting | Description |
|---|---|---|
| PD013 | 8 | Restore factory setting |
| PD005 | 400 | Set max operating frequency |
| PD004 | 400 | Set base frequency |
| PD002 | 1 | Set board potentiometer control |
| PD070 | 1 | Set analog input |
| PD072 | 400 | Set high analog frequency |
2.4 Water Cooling System Setup
Connect the water pump to the spindle using the provided water pipe. Ensure the pump is submerged in a suitable water reservoir and that water flows freely through the spindle for effective cooling.
2.5 Spindle Clamp Installation
Mount the 80mm spindle clamp securely to your CNC machine. The spindle should fit snugly within the clamp. Refer to the dimensions below for proper integration.
3. Operating Instructions
3.1 Inverter Control Panel Functions
The inverter's control panel allows you to manage the spindle's operation. Familiarize yourself with the buttons and their functions:
| Icon/Key | Feature | Explanation |
|---|---|---|
| 1 | Power-on Run key | Initiates power-on self-test and displays frequency. |
| 2 | Programming key | Enters and exits programming mode. |
| 3 | Jog key | Used to move display focus when setting parameters. |
| 4 | Up button | Up arrow key for parameter modification, page turn, and increasing value. |
| 5 | Down button | Down arrow key for parameter modification, page turn, and decreasing value. |
| 6 | Data Function key | Enters the parameter value setting state and saves the modified parameter value. |
| 7 | Forward and reverse switch | Switches between positive and negative rotation during operation. |
| 8 | Speed control knob | Adjusts the running speed of the spindle. |
| 9 | Stop reset button | Stops the running motor. |
3.2 Chuck Replacement
To replace the chuck or collet, follow these steps:
- Ensure the spindle is powered off and completely stopped.
- Use the appropriate wrench to loosen the collet nut.
- Remove the old collet and insert the new one.
- Insert the tool into the collet and tighten the nut firmly with the wrench.
4. Maintenance
4.1 Water Cooling System
- Regularly check the water level in the reservoir and refill as needed.
- Ensure the water pump is functioning correctly and providing adequate flow to the spindle.
- Periodically clean the water reservoir and pipes to prevent algae buildup or blockages, which can reduce cooling efficiency.
4.2 Spindle and Collets
- Keep the spindle and collet area clean from dust and debris.
- Inspect collets for wear or damage before each use. Replace worn collets to ensure proper tool gripping and accuracy.
- The spindle bearings are lubricated with grease and designed for long life; however, listen for any unusual noises during operation that might indicate bearing issues.
5. Troubleshooting
Common Issues and Solutions:
- Q: The spindle's temperature is very high after running for some time. Is this normal?
- A: Mechanical products generally have good heat resistance. The surface temperature is considered normal if it remains within 150°C. The suitable working environment temperature range for the spindle is -10°C to +50°C. Ensure your water cooling system is functioning optimally to dissipate heat.
- Q: What materials can this water-cooled spindle be used with?
- A: This water-cooled spindle is suitable for woodworking, aluminum, and various soft metals. It can be used effectively with a variety of milling cutters.
- Q: What type and number of bearings does the spindle use?
- A: The spindle is equipped with 4 steel ball bearings, specifically model C7002.

7. User Tips
- Always ensure the water cooling system is fully operational before starting the spindle to prevent overheating.
- Regularly check the spindle's temperature during extended operations. While it's designed for high temperatures, consistent monitoring helps prevent issues.
- Use the correct size ER20 collet for your milling tool to ensure a secure grip and prevent slippage or damage.
- Keep the work area clean to prevent dust and chips from entering the spindle or inverter, which can affect performance and lifespan.
- For optimal performance and longevity, avoid sudden changes in spindle speed where possible, allowing the inverter to ramp up/down smoothly.
