Installing Huanyung VFD on Heiz Zero3 Controller

[artmin]

I have this sorted

The Heiz controller has been configured for a Mechatron VFD. The manual is not very clear as to the 25pin port functions. The Heiz Zero3 port 'LPT2' connects to a second port on the PC (I am just using the standard printer port for LPT2 and a PCI parallel card for the more important LPT1). The port '0-10V' does then serve to supply the voltage & switching functions.

To avoid joining the ACM & DCM grounds of the VFD, I have configured for the Huanyung as follows:

Port 0-10V, pin 14 (constant 3.25V) connected to the 5V coil of a reed relay which is operated through switching (to ground) pin1. The switched terminals of the relay open & close FOR & DCM of the VFD

Port 0-10V, pin 18 (+ve 0-10V) and pin 25 (ground) then supply the variable voltage to control the spindle speed between VI & ACM of the VFD.

Configure port input I222 hood - query ready signal cabinet HF spindle LPT2 PIN 12 (for WINPC-NC)

The Huanyung is then good to go. The only thing wrong at the moment is the spindle speed is running at +30% across the speed range but I will add a trimmer to adjust this.

Thank you Boyan for saving me from smoking the VFD at the outset

Gavin, i want to do exactly what you have done. I have a Zero3 from Heiz and i want to install a spindle like this:

So that i can use WINPC-NC and just send speed control over the controller automatically.

Could you create or explain exactly what you have done? There is still a few things i don't understand.

Thanks, in advance

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?

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.

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?
