Help with broken/ smoking HY02D223B VFD on Openbuilds platemaker

That relay will short out the inrush limiting resistor once the big DC bus caps have been charged and the internal PSU comes up. As m_c says, it's more likely to be a symptom rather than the cause. If you manage to replace the green resistor, I'm pretty certain you will simply roast it again.

I think the question is whether you replace the HY inverter with a similar one or spend a bit more for an industrial drive - Jazz is recommending a new HY one.

No, I'm not.!! . . . Where did I say that.?

I just said the ones we fit now are very reliable which is the truth, I've probably had 2 or 3 go faulty in 6yrs, that last one being near 5yrs old and used every day in a commercial woodshop which isn't bad going for supposedly Cheap drive . . . I've also had an ABB go down in that time as well so buying industrial or quality isn't always a guarantee of reliability..
