It looks like a 3 phase machine, maybe one or two of the fuses have blown, which is a common fault with some power failures.
I do not know all the detail just try to help .
May be the new unit costs 4000 EUR.(and they can write)
Normally machine should have protection to this as a machinist thinks.
My friend is familiar with the electronics so assume the fuse is checked.
Somebody took this unit to check (big black box- supply low voltage and everything for servos) I am wonder the result.I try to get more info.
