    Default Mach3/g540/huanyang vfd connections

    I really hate to ask this because I know there are endless posts on this subject, but I'm still having a hard time finding a simple straight forward diagram of what ports on the g540 connect to what ports on the vfd (2.2kw). Also whether or not I need an external 10v power supply going into the g540, or if the vfd supplies it. Also whether or not I need a relay. I don't need to switch between forward or reverse, just spindle on/off and rpm control. I seem to be finding a lot of conflicting info on how to get this done. I think I can figure out all the settings for mach3 and vfd based on what I've found, just need a straight forward wiring diagram. Does one exist? Any help is greatly appreciated

    You need an external 10v (12v will work) power supply.

    I'm not familiar with your VFD, but I used the wiring digram in the link below.

    http://www.homanndesigns.com/pdfs/EN010_V8.pdf


    The red 10+ is the V+ from your power supply, connect this to 9 on the G540. The Blue Ground is the ground from your power supply, connect this to 7 on G540. Then connect the G540 pin 8 to your VFD Vout (or VFD command input). Then finally connect the power supply ground to the reference VFD ground. For my VFD I didn't need to supply V+ reference voltage to the VFD, it works fine without it, but your's might need that.

    For turning the spindle on, use the solenoid in the diagram above and wire it up the same using an output on the G540.

    Ok thanks, that helps. So it sounds like I do need the relay. I thought some guys were saying there's a way to do it without the relay, but I don't care, looks like it's 5 bucks or so. I'll get a relay and power supply coming. Thanks again

    Ok, so I noticed the thread the other guy posted right after me and al the man mentioned the usb adapter with plug in. Is it really just a usb into the pc and 2 wires to the vfd? If that takes the place of all the other stuff I would need to go through g540(relay, power supply, more wiring) then it sounds like the usb is quite a bit cheaper and simpler. Am I missing something? Any downside to the usb?

    You need to use one of the two freely available Mach3 huanyang plugins, but then yes, it's as simple as two wires to the USB > RS-485 adapter

    Ok, I think I'll try that first then. Just seems so much more simple. I imagine the usb method might be a little more prone to noise issues or pc related problems but I'll give it a shot since it's cheap. Thanks

    Ok, one more question. Maybe it's just the wording that's confusing me, but I'm reading that I need the rs485 AND rs485 adapter. Isn't it just the rs485 adapter (usb with 2 wire terminals) with 2 wires going from that to vfd? Or is there something in between I'm missing?

    Also the plug in is Mach3 plugin for Huanyang VFD | Le royaume d'éole
    You need a USB or COM port adapter to RS485.
