Thanks for the help Hood.

I will try the original transformer and see how it goes while setting up and testing.
If it works well all is good, if not I can come back to it.

Thanks
Alastair

You will likely need more capacitance than the original had, maybe not, but the few I have seen have less than the 1000-2000uF per amp that seems to be standard to keep ripple low.

Yes it will definitely need some capacitance added as there currently isn’t any! Or at least none that is external to the drives.
The 180VAC from the transformer is fed directly to the drives, each drive also has an external choke coil.

Ah ok, thats  the best way if the drives handle it but sadly none of the type normally used with Mach do. The AC servo drives I use take mains right in but suppose thats why there is a big difference in prices, well one of the reasons.
