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

Limit switches for axis. The print shows that you can wire the limits either n.o. or n.c. so if this is correct I would need to tell the board in the software how to look at these limits, I'm either going to get an input or loose an input depend on how i wire it.

If the spindle runs in the opposite direction than what the VFD shows in the indicator (also when X4 and X5 terminals are used) that sounds like your three wires going to the spindle are incorrect. All you need to do is switch two of the wires and your spindle will run in the correct direction.

Additional Information:
I am still waiting for the cable to connect my spindle so that doesn't come into play yet. I am just looking at the results of the led indicators as being reversed of what the documentation says that I should get by using the X$ and X5 terminals.

The E.Lu.5 Error code on your VFD is related to Low Voltage.

The recommended action is:
- 1. Check whether the input voltage is normal. (the voltage from the wall/breaker to the VFD)
- 2. Check whether there is a sudden change in load.
- 3. Check whether there is any phase missing.

Unfortunately, these three recommended actions will probable require an electrician to test the line going into the VFD.

I have wired up my 110v VFD and my 2.2Kw spindle and I get an E.Lu.5 code. My wiring is correct and the parameters are set to those for the VFD according to your website I found in a previously answered question from someone here. Any help would be greatly appreciated, thank you!!

Make sure to watch this video that I created to correctly connect a VFD to the Mach3 USB controller. Yes, the 10V terminal on this controller is an input. VFDs typically have a 10V output that can be connected to this terminal.

Additional Information:
The video is here:

[575] I want to run a SAKO VFD SKI780 by means of this break out board. On https://www.youtube.com/watch?v=P6xxHj6qYSA is mentioned that the 10V terminal on the BOB is an input connection and that it ha to be connected with an external 10V supply source to obtain a 0-10V PWM signal on the AVI terminal of the BOB. I this correct?

The transformer I used in the video was only to show the usage of the VFD and spindle. I recommend using a properly wired 220V outlet to to power the VFD.

If you use a transformer, make sure that the power (watts) of the transformer exceeds the VFD/spindle wattage (i.e. 2.2kW spindle is 2200 watts). You can find the current: I = watts/V which gives you I = 2200/220V, I = 10 amps. However, not being a professional electrician, I cannot inform whether your circuit breaker will handle this current load. I suspect that with 110V, I = 2200 watts / 110 V = 20 amps, so you will probably want a breaker with more than 20 amp to provide a margin of safety.

Please seek the guidance of a professional electrician since I am not, and you are working in an unsafe environment when connecting these high powered electrical systems.

Thanks and let me know how it goes.

Thanks.

The wiring diagram on the instructions for the Vertical Laser XL is meant as a general guide for all laser systems. The motor specific to the axis should be checked against the datasheet to insure proper wiring.

The 24V power supply should be connected to the laser controller. The 36V power supply should be connected to the drivers to power the motion electronics.

Additional Information:
My fault. Must have had that backwards. I'm sure he told me the right way.

Additional Information:
Not a problem. The laser controller has two terminals labeled for the 24V connection.

The 36V power supply works really well for stepper motor drivers as the voltage/current on this power supply allows for best stepper motor performance with this laser application.

The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

Additional Information:
I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

Additional Information:
Thanks for the information. Can you let me know the model of the VFD that you have?

Additional Information:
VFD Model # YL600-2S-2K20

Additional Information:
Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

Additional Information:
Does your VFD have a VI terminal?

It started with that but then once it was wired up it changed to this.

Additional Information:
Ok. Thanks. Please explain how you have the VFD wired to the 220v outlet.

Additional Information:
I have traced the black wire clear from the panel to the R terminal and the white wire to the T terminal and the ground to the E terminal. I have even used a multimeter on the terminals in the VFD while the wires are connected and the power is on, and I get 240V across the R and T terminals and 120 from R to Ground and from T to Ground.

My apologies. I didn’t see your latest wiring clarification response. Please connect the white (neutral) wire to the “S” terminal.

Additional Information:
So, i wired it up and now it does in fact power up. However, now it just gives me an ERR 02 code. What does that mean? the only manual that came with the VFD is all in Chinese. Do you have a book in english? Or a list of error codes?

Additional Information:
I have not seen a response to my previous comment. It has been a while since i have heard from you. What do i do next?

Additional Information:
Sorry about that. The Er 02 code in my manual says that there is an over-current at constant speed, over-current at deceleration or over-crrent at stop.
The recommended actions in the manual says:
1. Check whether the motor has got short circuit and whether the insulation of the output wires is good.
2. Check whether the motor is blocked and whether there is a sudden change of mechanical load.
3. Check whether there is a sudden change in he power supply voltage.
4. Check whether the insulation of the output wires is good and whether the motor has got a short circuit.
5. Extend the ramp down time.
6. Replace it with an inverter (VFD) of larger capacity
7. DE braking is too high. Decrease DC braking (this is only if you have a braking resistor connected).
8. The inverter has failure. Please send it to the factory to repair.

What I have done in the office is to check the resistance between the motor coils. The motor coils should have the same amount of wire winding on each coil. If there is a short circuit in this coil, the the resistance should be lower since there is less wire to travel. You can use a multimeter to check between pin 1 and 2, 1 and 3 and 2 and 3. The resistance should be generally the same.

Additional Information:
I worked threw all the other problems. the controller is now displaying Err 10. WHat does that mean.

Can you provide a complete list of error codes. Or documentation to support this device you sold to me.

id like to be able to integrate this thing into my growing business. i have been pretty unhappy so far with the lack of support. If you have any documentation, can you please send it to me. i cant be the only one having issues. Or even asking for help with these VFDs.

So I had my electrician hook it up as per your recommendations and nothing happens. Nothing lights up on the screen and nothing turns on. I have verified that the vfd that I was supplied is for single phase power and I have single phase power at my shop. It is a 220v vfd and I am supplying it with 220v. What do I do now? Is this vfd a bad one and do I need a new one?

I also place the controller very close to the drivers (on the back of the gantry). All of the cables are shielded. The only long cables are the mains power cables and the USB cable. The USB cable is shielded and contains active repeaters.

I'VE BUFFERED A PWM SIGNAL TO 0-10V ANALOG AND I WOULD LIKE USE THAT RUN YOUR 110V 2.2KW SPINDLE VFD. COULD YOU PLEASE DETAIL THE CORRECT WIRING VFD SETTINGS GET WORKING?

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.
