Re: Installing Huanyung VFD on Heiz Zero3 Controller
I’ll do what I can to help, though I’ll have to do a bit of revision as I don’t remember a lot of it.
The one component that I added to ensure separate grounds was a small reed relay: using lpt2 pin 14 for a voltage supply and grounding it using pin 1 let the relay output switch the vfd on & off. Pin 18 sends the variable voltage to the vfd for the variable speed.
How far have you got yourself?

Well, not far, since i haven't bought the spindle or VFD yet. I first need to know how easy is to install it, and if it works. From what i've seen it works, but all i need to do is create a decent cable to control the spindle speed and the on/off with the LP2 output?

Re: Installing Huanyung VFD on Heiz Zero3 Controller
It was an easy enough install but you will need to make mounts for the new spindle to attach to the HEIZ. This is my effort:

It's the 1.5Kw water cooled spindle that I bought with the body dia. of 65mm. I used a standard LPT cable for LPT2 and built a separate control panel.

I bought a long ribbon cable extension for the VFD control panel and I have a manual potentiometer that I can switch to if I want to overide the commands from WinPCNC. Also included is a temperature controller which controls 4 PC fans that are mounted on a van heater matrix and the water flow is supplied by a fish tank pump. That's the LPT2 cable that you can see and then the internal electronics are tapped from that.
Re: Installing Huanyung VFD on Heiz Zero3 Controller
I'm looking for something simple. I might connect the water pump to the second AC socket in the Zero3 controller (used for the vacuum, but not enough power for mine) and just had the LPT2 cable and connect to the VFD. The VFD will be close to the zero controller so i can control manually if needed. Should i be concern with the noise created by the VFD near the Zero3?

Well i've noticed that my Zero3 controller has an extra output, under LPT2, they don't have any documentation about it. Is it an output for the VFD?

Re: Installing Huanyung VFD on Heiz Zero3 Controller
Hello all,
I'm in the same situation. I've ordered a Chinese HQD 2.2kw spindle with sunfar vfd.
I don't understand the logic in zero3 controller. I use cncpod2 and kinetic NC together with zero3 controller.
This is the schematics for the VFD.

Should I connect pin 18 of 0-10V port to AI and GND to any of the pins 19-25 for speed control?
To turn on the spindle do I need a relay? I guess I can't use the open collector output because it shares the same ground in zero3 but not on the VFD?
How should I accomplish this? Use relay connected to any free ports? Which coil voltage should I use then?
Sorry about all the questions.
Thanks in advance.

Hi Anders
I am hoping that you have managed to do this as I am going to be doing the same. I think I have it in my head after reading through this thread but it would be good to get another, more recent confirmation.
Cheers
Tom
