Fanuc Servos Single Phase was created by mylastpolo
Hello everyone.
I am in the early stages of undertaking a CNC conversion on a manual lathe.
I have a Raspberry Pi 5 with Linux CNC installed, I have a pair of Fanuc servos with matching amplifiers removed from a suitably sized lathe and a manual lathe running it’s original 3 phase motor via a Jaguar VFD on a single phase UK supply.
I am quite familiar with motor control but servos are new to me, my question is would it be possible to run my servos/amplifiers on single phase?
I am aware of rotary phase converters but there must be other options, what type of servo are other people using?
The spindle motor is 3hp so that gives you an idea of the size of the lathe.
Thanks in advance.

Are the drives rated for 200V AC?
It may be possible to run from a single phase, but it is not advisable and should never be run at max power due to risk of blowing the rectifier. Rarely happens, though.
You have a bigger hill to climb, your country has 240V AC grid with +-10% tolerance, meaning it can go to 264V, rectified inside the drive that will be over 300V DC (on the phone, what is 264X1.41? ) and can easily blow the capacitors.
In short, i would not risk it.
A big 240 to 200V tranformer would be safe, but still single phase.

So it says 142v on the servo but then it says 200v inverter on the same tag. The machine they were removed from was on a 400v 3 phase supply, my 230v being one of those phases to neutral. I do have a transformer capable of the current requirement.
