most 3ph induction motors will run on 240/415 3 phase

No it is not, single phase input thru inverter drive to 240 three phase output to a delta connected induction motor used for speed control by frequency, with digital I/O for external stop start and optional potentiometer for remote speed control, I have fitted and commissioned plenty over the years
As for the 230/240 comment its still 240 in my house 245 actually
I accept that that may be the case for variable speed induction motors, but most 3 ph induction motors are single speed. They are not designed to run on 240V simply because the UK line voltage is 400V.
I said the declaired voltage is 230 V. Your actual voltage may be 245V at a particular time, and this is within the tolerance of the declaired voltage.
