VFD - E006 ERROR

[jcapitao]

Maybe i got shafted when i bought this machine. I have a 7.5kW spindle motor supposedly. When you look on aliexpress, in order to get a VFD to power my spindle, it seems that the VFD needs to be 3-phase to have enough power to drive my spindle. My machine is setup as 220V single phase......

Have they somehow rigged this vfd to trick it into running my spindle??

I think F1.00 should be set to 0 then.

and yes you probably need three fase

I've tried that, same result.

I'm actually going to try and set up the motor as per the youtube video i posted here earlier, and test it tonight. I'll post feedback here later.

To get 7.5 kW from one fase 220V you need 34A which is strange.

 

[jolbas]

I m not sure about the model. Strange that it s marked as model 200 on the inside.

I think that you must connect R,S and T to three fases 220V each an not use the neutral

I actually never set that side of it up. My machine came from China like that. Only wiring i removed was between the VFD and the NCStudio card.

Don't know if you know, this is just a conversion. Obviously ran fine in NCStudio....

 

[jolbas]

So the motor is the same as before too? Why change the motor parameters then? I do not fully understand but it doesn t feel right with 7.5 kW on single fase.

Did you try the auto tune (F1.11) and it didn t work?

I've just being doing some reading and youtube watching. This VFD, like a lot of them, is single phase in, and 3-phase out to the spindle.

Hhhmmm, that is the question. Why did i change the motor parameters. I followed the instructions of someone on here, telling me to reset the VFD to factory settings. Probably should have written down the parameters first, but there you go, i didn't.

I'm going to factory reset again, and then try the auto tune tonight when i get home.

 

[jolbas]

Maybe it s possible to lower the parameter for motor power to trick the vfd but I dont know how to set the other motor parameters to match that.

 

[jcapitao]

You and me both mate. I'll update here in about 4-5 hours.

The most powerful model in manual supporting one fase is 3.7 kW. So maybe that is the limit.

I would connect three fases to get full power as in the manual. But you maybe not have it in your workshop.

 

[jcapitao]

Yep, i only have single phase.

I see. And does that phase have a 16A fuse or less?

If 16A fuse then you should be able to set F1.01 to 3.7kW and I think F1.05 should be lowered by the same factor. In this case to 14.3A

Hi @masso-support



Finally, success. I factory reset the vfd, changed only the absolute minimum and now I have the spindle working and running correctly, without any faults/errors.

There is only 1 tiny problem. The keyboard stops working after about 5 seconds. I m guessing it s got to do with the interference I m seeing on the monitor as soon as the spindle starts. Attached are some pics of my cabinet/wiring setup. Maybe something is causing the interference, please advise.

@eti (wiring setup as you asked)

 

[jolbas]

I m curious. which parameters did you change?

My mouse sometimes not work if I have a pen drive connected on boot. Some pen drives are worse.

 

[masso-support]

That's great news, I wonder what the cause of the E006 was but never look a gift horse in the mouth.

The Keyboard issue sounds similar to an issue I had with my Machine where the USB pendant would stop working after the spindle was turned on and start working again after the spindle was turned off for 15 seconds and the USB reconnected. The issue turned out to be a Grounding issue. Is your VFD cable shielded and is it grounded at one end or both? Cable shield should only be grounded at one end and not connect to anything at the other. I realize that your VFD spindle cable won't have changed as it is only the Masso that has been added.

Cheers

Hi @jolbas

I'll update my list of parameter settings, and then you can compare the 2, but from memory all i did was the following:

1. Reset the VFD to factory settings.
   
2. Changed F0.01 to a "1"
   
3. Insured that F0.03 was a "0"
   
4. I found that F0.04 through to F0.05 was factory set to 400Hz.
   
5. Changed F0.07 to 50Hz.
   
6. I found that F1.00 was set at "2", which is not even in the manual....., very bizarre, anyway, left it at that.
   
7. Filled in F1.01 --> F1.05 as per the 400Hz settings on the spindle nameplate.
   
8. I then proceeded to test the spindle via the VFD keypad only.(I'd disconnected the wiring from the MASSO at this stage.)
   
9. Everything worked fine.
   
10. Changed F0.01 to a "1"
    
11. Changed F0.03 to a "1"
    
12. Connected the MASSO back up.
    
13. Test and successful run using MDI.
    

Like i said, i will resend the Parameter settings through once i've updated.

Hi Peter



Thanks for that, i'll have a look at my grounding tonight and let you know. In saying that, are you referring to the wiring coming INTO the VFD from the 220V supply, or the wiring on the OUTPUT side going to the spindle?

@jcapitao

Unsure if this would be any help but I mention it just in case. Another CNC forum I look at and occasionally contribute to regularly have users complaining about controller disconnects. One solution recommended is to use a high quality shielded USB cable. I note from your picture above the USB cable appears unshielded. This is one of the suggested cables.

 

[jcapitao]

Hi @clover

I'm guessing this would mean cutting one end of this shielded cable and hard-wiring it into the keyboard?
