There is also a derating on some VFD's for higher carrier frequencies, but in general manual mills are a lighter running amperage load. The Lagun mills that I have seen were 3Hp motors and up, so check the motor name plate and also the amperage to make sure the VFD can deliver that amperage in constant torque HD mode. The same goes if you are going to use a VFD for a 3 phase drive on the X or Y axis where you want fast stopping. I do not recommend them for lathes which require an external braking resistor for shorter stopping times. The Teco L510 does not support this and some of the generic Chinese VFDs are missing the braking circuity, otherwise the L510 is a decent low cost VFD for mills. If you plan to have quick stopping say for tapping, then you would want a VFD that supports and external braking resistor.
