Who knows?
But if it's 400V L-L, then it would be 230V L-N for three phase.

For a variable frequency drive, the input kVA is almost invariably lower than the output kVA at rated load.
It's simply a result of the lower output power factor. Nothing more complicated than that.

You can't eliminate core loss.
Unless you reduce applied voltage but then you wouldn't get rated voltage out.
