Hey Derek,
What semantics? Electricity is part of physics, we don’t try to discuss whether god exists.
Derek, if you have tried to explain the way how you as an electrician would deal with connecting this VFD, I didn’t get it. I don’t understand you, and especially not where you want to disagree here.
Either the data from the manufacturer (here: the output ratings) are there and is sufficient to you, and you use a way to calculate what the approx. input rating would be (I suggest this) in order to dimensionate an appropriate supply circuit, OR you say, the data that the manufacturer gives is incomplete or unreliable, and then you refuse to connect this VFD.
I don’t understand where you could see a third possibility.
But I agree with both ways to deal with this VFD.
