Every time I start the spindle in mach3 The reset button  go to fault.

Are you using limit switches? if so are the limit switch wires shielded? I had this same problem, replaced the limit switch wires with shielded wires and haven't had the issue since

Hi,
VFD's are very VERY electrically noisy.

I would suggest as a minimum add a beefy line input filter OR if you want real EMI control......a line reactor.

For example a line filter:

And a line reactor, this one is new but they can be had cheaper on eBay:

Note these go on the AC line side of the VFD, DO NOT put a filter between the VFD and motor UNLESS the manufacturer
specifically provides for it.
