I am running both a lathe and a mill off the same VFD. Both of mine have 1 1/2 HP motors, but one is 1725 RPM and the other is 3450. Works fine.
I set up a relay interlock system that cost as much as one motor. It uses an output from the VFD to prevent switching from one to the other while the first motor is running. I have a MachTach built into the remote control panel. The relays also switch between the two tach input sensors.
