Thread: Spindle 2?

One thing to watch for... unless you have a 3phase supply you need a VFD that does 1ph to 3ph conversion... these have a higher input current and surge than a 3ph input
A 1Kw VFD needs a 16A circuit so not practical to put it on a 13A plug. My VFD is screwed to the wall between the lathe and mill and both motors are wired to the VFD through a big (30A three pole) two way switch. The VFD has two sets of parameters stored, one for each motor.
My lathe setup is 1.5hp AEI (c1965) 3-phase with a Jaguar VXS-75 VFD courtesy of eBay (£75 the pair, bargain).
