Will any commonly available 240V VFDs go up to 400Hz? Need around
7.5HP.

At least some Yaskawas and Mitsubishis do; I've used them up in that
range on high speed spindles.

If you're ebaying for used Yaskawas, be aware that in the past many
were rebranded as Magnetek GPD5xx.

Actually..the other way around

Magnatek was bought by Yaskawa in 2001
