Thread: Tips for Newbie Huanyang VFD users

Hi Richard,

Yes it's ok to run without a motor connected.

Checking the IGBT's would be the logical next step.

From your comments it sounds like you know what you are doing, I'd be hesitant to offer advice if I thought otherwise, but if you are replacing IGBT's, I've used FGH80N60's you might have to replace the zeners as well, I think they are 18V from memory.

IGBT's are about $5 each (plus postage of course)

Ray,

Thanks - particularly for the zener thought.

I've been hanging around computers, high voltage and power electronics electronics for a while and am still alive! ;-) This is my first play with these hybrid devices and I wasn't sure how well they played with back EMF, etc.

I'll report back.

Richard

Ray,

Eureka! One IGBT is shorted across all pins. I'll now check the opto, zeners, etc to make sure it's the cause rather than an effect.

I've ordered spare zeners just in case - the opto's I have in stock.

Thanks again.

Richard

Hi to All.

I have difficulties setting up my 2.2kw water cooled spindle + VFD and mach3. I hope you can help me guys.
I have read'ed all this thread and got very handful info. But it is not enough to run my spindle as I want to. So my problem in few words is that I cant start my spindle from mach3.
Now I will try to explain my situation.
I have wired VFD and spindle and tryed to run it. I just hit the run button and spindle runs. No settings changed at all.
Than wired VFD to my BOB, that have a built in spindle control:

Connections:


Next, I setuped VFD setting as follows:
Change PD001 Source of Run Commands to '1'
Change PD005 Max operating frequency to 400hz
Change PD004 base frequency to 400hz
Change PD003 Main frequency to 400hz
Change PD006 Intermediate frequency to 2.5
Change PD008 max voltage to 220v
Change PD009 Intermediate voltage to 15v
Change PD010 Min voltage to 8
Change PD011 frequency lower limit to >100hz (120hz to start)
Change PD142 7 Amps
Change PD143 2
Change PD144 3000

Than, mach3 settings as sayed in BOB manual:


And nothing happens. I hit the start spindle, or enter G code and nothing happens.

I have measured volts from +10 and ACM it gives nearly 10 volts.

I getting this:

inverter reading when nothing is working, only power ON is this normal ?

And finally I changed PD001 to '0' and hit'ed RUN, the spindle runs fine, only when pressing STOP, I got this inverter reading:

And I dont understand what this means. I dont saw this till VFD setup.

So, please guys, I really need help to run this on my new CNC machine.

That is one nice machine you have there, fast rapids too.
Do you have the VFD manual? a copy can be found in the CNCZone Forum..

u327.4 I believe indicates present dc voltage, that is 327.4 volts, not
an error, the other displayed messages I can't identify.
The pictures of Mach settings display very small on my computer so I
can't read them.
Your VFD settings look ok to me but there are some others that might
need to be checked.
When I had mine working I had those settings you have but my spindle was
a 1.5 kw and the basic settings should be same. The settings additional
to yours to look at..

PD002 1 for external source of frequency
PD072 400 I have notes that says mine has to be set to 400
PD143 4 MOTOR POLES.. you have 2 but yours is a different motor
PD144 1440 RATED MOTOR REVOLUTION..but yours is a different motor
Using M3S10000 should make the spindle spin at 10,000RPM and variations
of the S value will change the speed. If you put a multimeter on the VI
and ACM you should see a voltage between 0 and 10volt depending on the
S value, so say max speed of your spindle is 20,000 rpm,so M3S20000 VI
would be 10 volts and M3S10000 VI would equal 5 volts etc..
I have a Gecko G540 connected to my VFD so unable to assist much with
your BOB. Not sure if this reply was all that helpfull now thinking
about it!!
Hopefully someone with the same configuration as yours will reply.
regards
Peter

Thank you for reply Peda.
I have about 3 manuals now, and unforchunently they all are about the same .

I will try to modify others settings today. But I'm facing with other thing - reset to factory settings. PD013 -> 08 should do this, but when I hit SET, and move to say PD001 setting are same as before. Maybe there is a trick to reset in factory settings ?

I found that PD013 is 01 not 08 that is writen in manual.

I tryed to measure Vout and got +2v when spindle not activated. As I understand that number must be +0 ? If I activate spindle with m3 the voltage is straight up to +8v (but spindle wont start. even when I set PD001 to '1').
Here is the video
Please Help me guys.

I wonder if at this stage you should try temporarily disconnecting from the BOB and use an external potentiometer to adjust the spindle speed and that will prove the vfd is set up properly for external control from your BOB. If you can control the speed in this simple way then the problem is with the BOB, connections or Mach3 settings.
Post 315 has the set up using a potentiometer.. note the drawing is missing the left pin of the pot going to ACM. When I used this method as a test I just hard wired FWD to DCM

Look at post #181 there is a good document showing Mach settings
https://www.woodworkforums.com/f170/t...0/index15.html
Again your control hardware is different to mine.. but i think if you can eliminate the vfd settings at least you have norrowed your search area.

Hi TadasM

Read this manual and set your PDOs accordingly. Hopefully that will do the trick.

Bob, thank you for your reply.
Today I was able to start my spindle from mach3. there is some misunderstanding in digital outputs of BOB.

But I have other problem. when I start my spindle (m3s8000). the spindle goes to 24000 rpm. and when I input m3s8000 again the spindle goes ~9200 rpm (reading in vfd screen). But than I input say m3s9000 and spindle goes about 17000rpm. And if i input m3s10000 spindle goes 24000rpm. I know that there is setting who has to be changed but I setupped vfd as in many manuals that I found here.
Thank you for your help.

Hi TadasM

I suggest that you do a full reset of VFD settings and then start all over again.

I also suggest that you adjust the 10v supply to show EXACTLY 10v.

Bear in mind that when I wrote that guide it was for a 1.5kw spindle and matching VFD. As far as I know, there is no difference in the PD settings required, but I could be wrong as I just don't know.

PS You will probably need to make an adjustment in at least one of the PD settings to allow the maximum amps to reflect your own setup. (2.2kw)

is a ful reset pd13 set to 1 or 8

Bob,

My BreakOutBoard generating about 9.5v. And I don't know if I can adjust the voltage (probably not).
But my lower voltage is 2v not 0v (measuring VI and ACM) when spindle is in idle (not running). How can I adjust that ?
I will try to reset and configure VFD again (third time).
One more thing - the button in mach 3 works oposite way that it should (spindle ON to vfd means off, spindle OFF to VFD means spindle ON. I have changed setting in Ports and pins -> motor outputs -> spindle -> Step Low Active must be activated to work button correctly. Maybe this setting messing up something in voltages too ?

Azzrock,
As manual says to reset VFD setting to factory settings PD013 must set to 08, but to my VFD 08 does nothing. Mine PD013 setting must be set to 01 that way factory settings are set.

thanks tadasm great answer.
