If you have direct access to the resolver it would be worth a thought to
use a "resolver to digital converter", e.g. something like this:

Then you can connect the encoder emulation output to LinuxCNC.
Most Resolver converters (including the Mesa 7i49 and the STMBL drive)
expect to be supplying the excitation signal and read the output
synchronously to that signal.
If the drive is already supplying the excitation most of the
off-the-shelf converters won't work.
Yes, these ones I know, too. This was meant more like an example.
Also, the Magnescales have a much finer pitch and are on the actual
slides, so there is no worry about backlash between the motor and the
table.
Of course, the use of Magnescales should be the first choice.
