Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

I am looking at purchasing your 2.2 kw water cooled spindle. I'm assuming it comes with the VFD. I have a rotary phase converter in my shop. Are these spindles 3 phase? And if so, can I bypass use of the VFD and control the spindle speed by the CAM software instead? Or is the VFD an absolute necessity to use on the spindle?

A standard water pump like this one will work: https://www.buildyourcnc.com/item/pneumatic-hydraulic-water-pump-370-Gallons-Per-Hour-220v-110v

You will also need silicone tubing at 1/4" ID and 3/8" OD to connect from the pump to the spindle: https://www.buildyourcnc.com/Item/pneumatic-hydraulic-silicone-tubing

And a bucket to hold the water.

You may also consider CPU cooling systems which can actually be fastened to the back of the gantry. We do this for the Fabricator Pro machine. The CPU cooling I would recommend is a small pump and cylinder with a heat sink, or a small radiator.

The VFD does come with a manual that details the wiring and connection specifications, terminal features and a list of the parameters. There is no information on how to connect it to Mach3. It does detail the specifications within the parameters and terminal features on the analog input that is used with Mach3 and other control programs.

It seems that the water cooling lines inside my 2.2KW spindle are clogged. Is there a way to unclogg them?

To rush/clean the water from the spindle, you will need a air compressor or air tank that you will use with a blow gun, which you will rush air through one end cleaning the water from within the spindle.

There is no specific manner in connecting the water lines to the spindle. No specific output and input locations, only the diameter which we use is 1/4 Inside Diameter and 3/8 Outside Diameter (you might find another one that works just as well).
Unscrew the 2 hose nuts and feed the tube through (will be snug), and adjust the tube on the hose fittings and screw the hose nuts down. Feed the tubes through your machine towards the water bucket, making sure it will not get caught on any moving parts and cause a jam/leak, and fit one tube to the outlet of your water pump and leave the other tube to the bucket as a return line. (unless you are using a cooler like a radiator, then feed it to the outlet of the radiator and to your water pump)

Are there any special instructions regarding connecting water lines to the 2.2k spindle?

I have not tried connecting a 110V spindle to a 220V VFD; however, the parameters in a 220V VFD do allow changes to the values for the spindle motor. If you do plan on connecting the 110V spindle to a 220V VFD, damages can occur, so I would not recommend it.

With that said, here is the output of an LLM:
Using a 220-volt VFD (Variable Frequency Drive) to run a 110-volt spindle is technically possible, but it requires careful setup to avoid damaging the spindle. Here's what you need to consider:

Check the VFD Specifications: Ensure that the VFD can be set up to output the correct voltage for your spindle. Many VFDs are capable of outputting variable voltages and can be configured via their programming settings to match the voltage requirements of the spindle.

Adjust the Output Voltage: You'll need to configure the VFD to output 110 volts to match your spindle. This is crucial because supplying 220 volts to a 110-volt spindle would likely damage it permanently. Check the VFD's manual for instructions on how to adjust the output voltage settings.

Set the Current Correctly: Besides voltage, make sure the output current does not exceed what your spindle can handle. The VFD should be configured to supply the current at the rating appropriate for the spindle’s power and voltage requirements.

Consult the Manuals: Always refer to the manuals of both the spindle and the VFD. These documents can provide specific guidance on compatibility and settings.

Consider Professional Installation: If you are not familiar with electrical systems or if the manuals do not provide clear guidance, it may be wise to hire a professional. This helps ensure that the setup is done safely and correctly.

By taking these steps, you can safely use a 220-volt VFD with your 110-volt spindle, ensuring it operates efficiently without risk of damage. Just be meticulous with the settings and when in doubt, consult with or hire a professional.

[77] I have a 110 volt 2.2kw water cooled spindle. Can I run it with a 220 volt VFD?

Do you have the Pokeys57CNC connected to a 24V external power supply?

Additional Information:
Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

Additional Information:
Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

Additional Information:
And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

Additional Information:
Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.

Click the link to add information to this solution:
My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

They do have a similar looking thread as the G1/4”, but I will confirm in the morning. We use the G1/4” on the pump and radiator so it will be easy to determine this fit when I get into the office.

Hello what is the thread size of the water cooling fittings on the 2.2kw spindle? I am wondering if I can replace the fittings with standard pc liquid cooling fittings, which are G1/4".

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

[77] Hello. I’m interested in buying a water cooled spindle and VFD. I have an Avid Pro CNC and would love to control it using Mach 4 but I keep hearing it’s difficult to integrate. Also, is the water pump 120 or 240? I’d love any advice etc. eBay is a web of confusion with all of the options. Thank you.
