I need my spindle and cnc electronics repaired. How can I fix it?

It is not necessary to connect the spindle VFD (Variable Frequency Drive also called an Inverter) to the computer or CNC motion electronics. The VFD can be controlled independently using the control panel on the VFD. The control panel has the ability to control all aspects of the spindle including Speed, Torque, limits, etc. However, you can connect the VFD to the computer so the CNC control program can control the spindle during the CNC Machine operation. You will need to connect the VFD to the computer via a serial conection (in this case, it is the RS-485 protocol).

The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection.

The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
- PD001 - value 2 - Enables with communication aspect of the VFD
- PD002 - value 2 - Enables frequency control from the communcations port
- PD163 - value 1 - VFD address
- PD164 - value 1 - Baud rate of 9600 (speed of the communication)
- PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

Copy the dll file to the PlugIns folder of mach3.

Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

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

LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

Additional Information:
After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

Additional Information:
To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

In the VFD parameters:
PD001: 2 to accept RS485 commands
PD002: 2 to accept frequency comands
PD163: 1 to RS485 slave address:1
PD164: 1 RS485 baud rate 9600
PD165: 3 8bit, no parity, 1 stop bit

Make sure LinuxCNC is also set accordingly:

The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

In the options step of the stepconf wizard:
- Check the Include Halui user interface component.
- Check the Include custom PyVCP GUI panel.
- Check Spindle speed display

You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
net spindle-cmd-rpm-abs => vfd.speed-command
net spindle-cw motion.spindle-forward => vfd.spindle-forward
net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
net on motion.spindle-on => vfd.spindle-on

The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

Under the custom_postgui.hal file, change this line:

from: sets spindle-at-speed true
to: net spindle-at-speed => cfd.spindle_at_speed

and add the line:

setp vfd.enable 1

When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

How can I make LinuxCNC control a spindle?

It will depend on how you configure the machine to use the Laser and plasma. Is the laser on a separate gantry? That will determine the way you will connect the laser control system or if you use a typical CNC controller. The plasma will need inputs of THC on, THC up, THC down and outputs to trigger the plasma torch. I recommend the Pokeys57CNC for the plasma and you can also fire the laser with it, but you will not be able to do engraving with the laser unless you use a laser controller. If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using, or if you have the laser on a separate gantry, you can use a traditional laser controller connected to the stepper motor drivers on that gantry.

Users response:
I was planing on using same gantry, and installing plasma and laser module on z axis along the side with current router. Perhaps if it’s needed installing another z axis on current z axis. So that when I use plasma, router z will be homed and plasma z axis will be able to utilize thc.

When you say “If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using,”
If i install laser controller, pokeys and router motion card, do you mean all ( axis and router/laser/plasma) signals or just the one that controls router/laser/plasma?
I was wondering if I could jump (parallel connect) axis signals from card to card without ?
Also do you prefer ethernet card or usb?
I really do appreciate your help :) thanx again.

Buildyourcnc response:
Not a problem at all.

Remember that with all of that weight on the z-axis, you will not be able to do efficient raster style engraving.

By putting the laser on another gantry, say at the far end of the table, then you would be able to use a laser controller that controls its own stepper motors and the nozzle can have fast swing motion for engraving. With the laser on the z-axis of the spindle (like see on the greenBull), you will only be able to do vector motions for the laser.

You can also have a CNC interface and laser controller controlling the same stepper motor drivers, but you will need a few tri-state buffer chips where you can use a toggle switch for which controller has control of the drivers.

If the VFD is presenting an ER 4 error, the VFD is most likely damaged. The VFD will either need to be serviced or you will need to purchase another VFD. The latter is probably the less expensive option, unfortunately.

If you are using a silicone tube with a 1/4” ID, it will fit the nipple of the 1.5kW spindle water connections measuring an OD of 0.31”. The silicone will stretch and you will need to use water or saliva to help the tube fit.

The tube ID being smaller than the nipple will help the seal prevent water from leaking.

You will need a 24V relay to control mist using the Mach3 USB breakout board. The wiring diagram (link below) will show one of the output terminals (O1, O2, O3 or O4) connected to one of the leads of the relay. The other lead is connected to the V+ to complete the circuit. The other part of the relay is used as a switch to control the mist on/off.

You'll need to twist and pull the collet while also canting it side to side until it comes free from the nut. It is not actually attached to the nut it just takes some jiggling to separate the two.

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

I ordered a 1.5kW 110V Spindle on 11/28. It still shows "processing." Is this on backorder? Any ETA I can expect?

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.
