Sorry I forgot to attach the picture.
I'd like to see that with the pink cover carefully removed.

Hi Andy, the encoder is the one on the picture I'm attaching now. The
model number is *αI64 *and then TYPE A860-0365-T101.
If the 8i20 can control both servo motors It surely would be a lot easier
to replace the encoders in case they don't work with the HOSTMOT2 Fanuc
component. I really prefer to avoid replacing the motors because they are
already there with all the couplings and even the brake assembly for the X
axis.
The Z axis motor is rated at 3800 W but I don't mind having it limited to
2200 W given the kind of work this lathe does, (mostly cast iron parts
with really light cuts so no big cutting forces involved).
Thank you!

The voltage and current are inside the range of the 8i20.
The 8i20 needs to be externally commutated (In HAL) using the "bldc"
hal component using the encoder feedback.
I have been using 8i20s in my mill and lathe for several years with
few problems.
The STMBL drive has a Fanuc encoder component:
https://github.com/rene-dev/stmbl/blob/master/src/comps/encf.c
and would probably be a very good choice, if you can find any. They
aren't really available at the moment without making them yourself and
sourcing discontinued parts.
