Ok, this morning my VFD died. YL600-2s-2k20 for 2.2KW spindle. This was bought from a company that said it was able to use 110V. No smoke, no pop, just the slow winding down of the spindle. The display on the VFD had something on it (CN????) but before I could read it, the display went off. Powering off/on did nothing. Connections look good. Power is there. One tiny LED D12 is on, that is all.

I've had the VFD for about two years.

So, that brings me to now. I'm looking at some VFDs on Amazon and am looking at 220v models such as:(VFD 220V 3.0KW 4hp Variable Frequency Drive CNC VFD Motor Drive Inverter Converter for Spindle Motor Speed Control HUANYANG HY-Series(3KW, 220V))

or should I step up to the 4.0KW 5.5 HP?

Any suggestions?
If you have a similar setup, I'd like to hear from you as well.
Thanks!
Charles
