Help Italy Nikigio RCD jumping

[nikigio]

I own an Axiom that sometimes blows my RCD (lifesaving differential). Not a problem with my line.
The electrospindle has a VFD controller and the cause may be the presence of a filter (I don't know what we're talking about) to be excluded.
I ask if it is the solution and how to do it.

Thanks

....and I have no idea what you just said.

It sounds like he's saying his Axiom machine keeps tripping his breakers, but that he believes there's not an issue with his circuits.

Then, I think he asks about, perhaps, a voltage regulator that is not compatible with his EU power grid and is asking if there is a way to bypass or work around it.

However, I don't know the answer to that question if that's, indeed, what he's asking.

All correct!
The spindle of the cutter is controlled by an inverter.

If I exclude the EMI filter I solve

Thanks

It sounds like he has a 110V Iconic machine, which can not be used with GFCI outlets...(Which are labeled as RCD in parts of Europe).

The VFD inverter is often thought to be the source of this trouble, but it appears to involve both the VFD and the spindle.


Since these are technically 3-phase motors, the invertor is changing the 1-phase 60hz power to 3-phase 200hz for spindle control...and during operation of the spindle a very small (micro voltage current leakage may occur) which triggers the sensitivities of the GFI outlets.

I'm not sure if the same characteristic will follow the newest Iconic machines, where that VFD is being changed...but it operates perfectly fine on a standard outlet. Unfortunately, some residential building codes require that all garage and shop outlets are GFI to meet code...so home owners may havre to change outlets in those cases.

*There is a CSA approved 220V Iconic machine on the horizon that will do away with this trouble (marketed specifically for Canada and EU markets)...but will be available at request for US customers as well.

Exactly !!
That is the question!
But the solution ?

Thanks .

My VFD and the differential point (current size).

According to what Axiom said:

You need to change your outlet to a non-GFCI (non-RCD) outlet and it should fix the problem.

I hope that is more Google-translator friendly.

Grazie per la tua disponibilità.!!
