Hi Jazzcnc,

Thanks for the advice. I was thinking that the main spindle motor can be disconnected from the incoming supply and run purely from the vfd. The rest is running from the two good phases from my current inverter, which I am told ran with this machine when the drives were tested (some time ago). This is going to be a big project for me, and i have very little experience of this type of machine.

The manual is available here but it doesn't show the actual diagram i am looking at.

I am trying to find a copy of the wiring diagram online but failing that i will try to get a couple of pictures on my phone and will upload them shortly.

Thanks for the reply!

Mort
