I think the motors are 1.5KW DC servos, the spindle is 11KW for 100% duty cycle and 17KW for short periods, 3450 RPM, also DC.
Not using resolvers, nothing i can find works with those, they are some type of reversed resolvers, so i am replacing them with 2500PPR encoders i had new. Had to make some 3D printed mounts with bearings for the encoders, and now i have to mount those and wire them, not easy as the existing cables go through very thick shielding with soldered connector on one side....
Much easier to add new cables and leave the old ones dangling in the breeze ! :)
Those are nice machines, to bad you had to let those go.
Then again, i may have to let this one go, very soon. Or i can drag the retrofit ... :)

Yes, it is expensive to change those motors if they can be solved with encoders on the 7i77, if the amplifiers already have an analog input. here the servo motors of that power are Chinese with a driver around 500e.
if you already work on machines, you should leave one good lathe for yourself, this one looks good

Nice one Tommy, to get a beast like that under LinuxCNC control. You are a master!

can you post your configuration file ? I'd like to see your tool changer arrangement, sounds similar to my cincinnati

Ma nije, sad mi nije vazno vise, za drajvove me nije briga, imam jos 4 manja DC servo drajva koje mogu da koristim. Zadnjih dana radim neke druge stvari, pa kad budem mogao pokusacu da nadjem koje zice sta rade za postojece drajvove, sanse su da je jedan propao posle prvog napada miseva, to sam video na ekranu kad sam poslednji put ukljucio masinu pre godinu ili vise dana.

Did some more reverse engineering yesterday, so not much left to figure for the axis drives, although one might be dead as i wrote here last time i turned it on about a year ago (first mice attack that i was not aware off) it did show that on screen, but when i programed in the parameters (not fun at all) at one point in time it did not show any errors, hence i would like to have a go at burning them...hmm .. testing them! :)
Some more hieroglyphs attached ...

ah ti misevi, ne znam koliko deluju oni visoko frekventni uredjaji za rasterivanje, mada je sad i kasno, dobro je da si dosta stvari spasio, motori ce proraditi;) i dobro je malo odmoriti uz neke druge probleme, toga bar ima svuda i uvek:) ...ako ti sta treba od mehanike samo javi, tipa klizne staze vretena ose, manji dc motori ..toga imam.
