Hello!
I have a question if anyone from EU has a spare 8i20 drive (can be
used as long as it works correctly) that I can purchase. It seems that
I have to replace 3rd Yaskawa servodrive in my Biesse retrofit.
Eusurplus are out of stock, I did not find any other sellers that have
them and I really do not want to deal with customs bureaucracy.

Some Q's Viesturs:
Is Yaskawa gone?
and do you still have the failed units?
What is the power supply voltage?
Do you have an instrument that can measure both a capacitors capacity
and its ESR?
And make basic checks on power transistors, including big VFET's?
With that ESR instrument you can probably restore them by finding and
replacing the capacitors that have now aged out and failed, usually
effectively open.
