### Question #: 14632

Question: What is the minimum RPM for the 2.2 kW spindle? Info on spindle page says 0-24,000. Elsewhere in this knowledge base it says 6000. My edge finder has a1500 RPM limit.

Current Solution

The lowest Hz for a 2 pole 2.2kW spindle is 250 Hz. That works out to 15,000 RPM. If you need lower RPM, a separate spindle will be required. This is typical for industrial CNC machines where spindles are changed out to mill on different materials.

Does that mean the 2.2 kW spindle sold by BYCNC is a 2-pole, not a 4-pole? There don't seem to be specs on the website for the 2.2 kW spindle.

I currently have the 1.5 kW spindle from BYCNC and can run from 0-24000. 1500 is no problem. I never mill at that low of a speed, just use the edge finder to set the workpiece coordinates.

### Other Possible Solutions to this Question

• I have the 2.2 kW spindle and VFD for 110v, just wondering what amperage this draws, as my electricain buddy is telling me I need to put in a 20 amp breaker for this. I cant seem to find any amerpage draw on the INPUT label

You can actually set a current limit in in the VFD using the programming process and the specifications in the manual that came with your VFD. You can expect the spindle at 220 Volts AC to draw (using the standard formula):

For Volts, I will use 230 as the range is generally 220 to 240.

Watts = Current * Volts

Can also be written as:

Current = Watts / Volts

Current = 2.2kW (2200 watts) / 230 volts

Current = 9.6 amps

• BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?

The leadscrew length for the greenBull long Z-axis is 47 inches.

• What is the minimum RPM for the 2.2kW spindle?

Spindles with 2 poles, which is typically for these types of spindles will have a minimum RPM of 6000 RPM or 100Hz; however, I would not run the spindle below 15000 RPM or 250Hz to give a safety factor and no damage will occur.

If you have a 4 pole spindle, then much lower RPMs can be achieved, and with higher torque than a 2 pole spindle. The 4 pole spindle will require more power than 2 pole spindles and will not be able to achieve as high maximum RPMs.

• I WIRED MY VFD (2.2KW VERSION) AND TRIED TEST RUNNING THE SPINDLE. CONFIGURED TO YOUR SPECS ON THIS WEBSITE, ONLY ISSUE IS WE GOT AN ERROR CODE. ERR 02, DO YOU KNOW WHAT IS? OR HAVE A LIST OF CODES? THANK

Can you provide the model number of your VFD?

Yes, I have the "YL600 - 2S - 2K20"

It just came with a small booklet that is all in Chinese...

• I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

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.

• LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.

BYCNC Response:
This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

User Response:
I am using the cnc planet software for your USB board. Are the limit configurations in this software?

BYCNC Response:
Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

• I JUST RECEIVED A REPLACEMENT SPINDLE (2.2KW 220V). HOWEVER, WHEN ATTEMPTED IT USE THE NEW SPINDLE, WOULD ONLY REACH 1500 RPM. IS THERE SOMETHING NEED TO CHANGE ON CONTROLLER?

VFD settings........
1) To program the VFD, wire it up, plug it in. It takes several seconds to come to life.

2) Push the PRGM button to enter programing mode.

3 )Push the SET button. The display will read PD000.

4) If you push the SET button again, it will display the present setting of PD000.

5 )By pushing the up or down arrows, you can change the setting to whatever it needs to be. (This is just an example. PD000 needs no changes)

6)Push the SET button again to lock in the setting of PD000 and advance to the next number, in this case, PD001.

7) Push the SET button and it will display the present setting of PD001. Again, use the up and down arrows as necessary to set PD001, then push SET again to lock it in.

Note: You can also scroll through the PD numbers with the up and down arrows.

8) make all settings this way.

9) by pushing the SET button you can scroll through the settings. First push of SET moves to the next number, second push displays it's setting, third push moves to the next PD number.

Note- If you take too long, it will leave the programing mode on it's own. If it does, just push PRGM again to return to programing mode. Then press SET and continue what you were doing.

10) Start with PD013. Set it to 1, which returns the settings to the factory settings.

11) Then set PD005 to 400, PD004 to 400, and PD003 to 400 IN THAT ORDER.

12) Then set the following: PD041=8, PD144=3000

13) Set PD209=50

That's it for the programing. You should get 24000RPM when you push RUN.

• I am interested in buying the water cooled 2.2 KW spindle for \$339, how much does it weigh?

The weight of the 2.2kW spindle without the VFD (variable frequency drive or inverter) is 11 lbs or 5 kg.

The 2.2kW spindle with the VFD is 15 lbs or 6.8 kg.

• [801] Is this enough rating for a Nema 34 motor with max 6 amps? Also what about a 220V 2200Watt Spindle?

For the NEMA 34 stepper motor with a maximum current of 6 amps, 18 AWG wire would technically be sufficient. According to the American Wire Gauge (AWG) standard, 18 AWG wire can handle up to around 10 amps of current in chassis wiring and around 16 amps in power transmission. If you are considering running a very long length of cable from the driver to the stepper motor, you may want to consider using 16 AWG.

As for the spindle, this wire gauge is well-suited. There are three phase shifts, each at 120 degrees and each conductor is carrying only 1/3 of the power. At 220v, 2200 watts / 220 V = 10 amps. 1/3 of 10 amps is 3.333 amps, so each conductor will be have a load of 3.33 amps.

• I ordered a 1.5KW 110 volt spindle. I just received the box and the spindle clearly says on the foam packaging and the side of the spindle that it is 220V. I think you shipped me the wrong spindle

Did this spindle come with a 110V 1.5kW VFD?

The reason I ask is because the 220V 1.5kW spindle may work well with the 110V 1.5kW VFD. I believe we did the test prior to shipment.

I have a 110V HY01D511B VFD already. I did not know they would work together. I will give this a try.

If you did't get the VFD paired with the spindle from us, then I would not connect the 220V spindle with your VFD. Let me ask my technician and get back with you.

My technician said that it should work since the 220V 1.5kW spindle worked with our 1.5kW 110V VFDs.

Remember to seek the advice and guidance of a professional electrician when connecting these types of high powered devices.

Do you have any info on the settings? I would rather buy a pre-configured VFD from you if you don't have the settings for my HT since I have already fried one spindle because of lack of documentation from the manufacturer. If you can setup a VFD that works with the spindle you sent at 110v input voltage I would be fine with the extra expense.

• I purchased a vfd and spindle from a friend, his set up is 220. I don't have 220 in my shop. My question is can I use your 110 vfd with this spindle??

Depending if the spindle can work with this specific VFD, it might be possible. However we would not like to risk you working unit, with a possible match so we would like more details on your specific model and any information available on the spindle itself.

Response
The only info on the spindle is 2.2KW 400HZ 220V. Made by Zhong Hua Jiang.

Was originally on a Delta C200 vfd. That is 220 single phase.

• HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

BYCNC response:

Milling aluminum is no problem with our machines.

Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

• My Z-axis seems to be reversed on a fully assembled machine... I've tried reversing it in the config settings on Mach 3, but to no avail. What do I need to do? IS this a wiring issue that was not done correctly at the factory?

If your Z axis is moving in the opposite direction, go into Mach3, click on config, ports & pins, then click on the motor outputs tab. You will see the axes labeled on the left and the parameters labeled on the top of this dialog box. Toggle the dir low active for the z-axis.

What if I'm having the same issue on a different axis?

You can follow the same procedure as with the z-axis. When you get to the motors outputs tab, toggle the dir low active checkbox for the axis that you would like to change.

If you are using another control program, let me know and I will add the recommended action here.

• I have a 2.2kw water cooled spindle with a YL620-H VFD. The VFD uses the P#-## program format. I believe I have all the correct settings setup but when I turn the unit on, it spins at about 200-300 RPM regardless of what frequency I choose. Do you have the correct program parameters in this format for this unit? Thank you for your help. Huibert Mees

• What wire do I need to power the spindle (ie, from the 220 outlet to the spindle). Would a dryer cable work? Is there specific amperage the wire needs?

The wire that is connected to the spindle can be a simple extension cord, that you find at a local hardware store. However there is a missing wire that is required(ground) which will have to be the same amperage of the extension cord.
