Mazak Micro Slant 15 Retrofit

Changed the fuses today and turned it on, mice must have eaten something as it turns on all the fans, spindle drive is powered and waiting at zero speed, but nothing else, so no computer, no axis drives, no controller, no hydraulics ! Cr@p !
If i have time tomorrow i gona have to do a deep dive in it.
When pressing the enable button, some relays do click and it gets a very short pulse of power to the computer/console, oh and the cabinet light works !
I am taking this as a sign to retrofit it !
There is also a small issue of the spindle drive powered by 3 phases at over 500V each! Damn, that can do some damage ! :woohoo:
Does anyone have a 3 phase spindle at 11KW to give for charity ?
The existing on and all axis are brushed DC motors.

Did some diving today, the outcome looks grim.
I did recall that in autumn last year we had severe hail storm and my shop was flooded badly, some of the polycarbonate windows were blown in so a lot of that hail/rain got in the shop and consequently inside the monitor cabinet, it had some water in it and everything inside was wet to the touch.
I used a phone camera to record what is happening behind the machine as i still have not figured out how to be in two places at once, so i would record what is going on with the LED's on the drives/electronics/power supplies etc, and then watch that. So far only one of the axis drives fails to turn on and the main computer, probably because it was under water at one point in it's life.
So tomorrow will most probably be decision day, yank everything out, or dive some more ! I am leaning towards yanking, a lot of yanking!
Could not find any damage done by mice, so that was disappointing.
This thing has two big transformers, as i found out yesterday, and chasing the wiring through 5 cabinets on all sides is no fun, but at least it is good cardio.
To bad i do not have some AC servo drives and motors, that would have made the decision much easier.

It is on !
A small tantalum capacitor decided to hog all the power for itself, so now it has one missing leg!
Finding a faulty 3X5mm capacitor on a 3.5 ton machine is not easy, but i do need the cardio.
Now X axis servo drive does not come on, all the parameters are lost since the battery went flat, lube pump is clogged .....
Will post some pictures later.

It has always been a bit of a mystery to me why these machines can't store those parameters in an eeprom. Those machine service guys must make a fair amount just going around punching those numbers back into systems where the battery has gone flat or where the battery change has not been done right.

Not sure eeprom existed at that time, prom did.
But i am pretty sure a lot of machines built at the time of eeproms still use the same battery backup system for good knows what reason, as price was not an issue on a 200K machine or more.

And another setback:
Had a deeper look at it today to morally get prepared for the retrofit and hit a snag, turns out it uses brushless resolvers so two things started running through my mind:
1 i have nothing i can use for that, so : PCW, help !
2 Andy is gonna be happy, he loves resolvers
Just now thinking maybe Andy is right, so i should try resolvers, ..... or make mounts with shafts and bearings for the f.... encoders i do have.
F..... since they turned out to be the reflective type so any miss alignment will render them useless, paid 69 Euro a piece, and 2500PPR, have 5 of them, differential with index.
O what a mess !
