Yes I know Greg. But they are not worried someone has bought the land for
houses and I think they got some serious money for it. Like probably 40
million nzd.
So they just want it gone.
And I'm happy as to get it!
I paid 5k nzd which is about 3000usd so got it for a song.

They could have spent a whole lot less than that doing a LCNC refit.

Hey Andy.
Heidenhain is not very well supported here in NZ.
I went down that path already on my last machine and won't do that twice
lol.
They are actually moving and just want it gone now.
And the 25k nzd was over 10 years with all the problems it had. It's
almost as if it has a dodgy ground

It is an arrangement of 4 or 6 diodes (4 for single-phase, 6 for 3-phase)
They are often packaged as a unit, but might also be made of discrete
diodes.

Actually Peter and Andy.
I have a 400v to 240v stepdown transformer on the lathe at the moment as
fanuc uses 240v drives in Japan.
The transformer is massive
So I already have 240volts ac three phase power in the machine. Just need

I have no idea currently how to rectify

I don't really know much about it. there is a big heidenhain service

Do you know anything about that signal? The Mesa firmware is capable of
providing a 3-phase PWM, in fact that is exactly the control scheme used by
the 7i39
ah I see thanks for that I couldn't work out how that was supposed to work
so that is not going to happen then on the cnc mill. guess I will need to
buy chinese servo drives and motors if the existing heidenhain inverter
doesn't work and I can't interface with it. apparently it takes a PWM

The 8i20 takes DC input.
If you rectify 400V three-phase then you will get 565 V.
400V is the RMS voltage. A rectifier charges the capacitor to the

Hey guys
I have been looking at the mesa 8i20 servo drives and thinking about using
one to control a 3.45 kw heidenhain motor I have here
the max power the servo drive can control apparently is 2200w so the servo
drive is slightly under powered.
