You need to flash that bitfile with Mesaflash, and your INI / HAL config will be something that PnCConf probably can't help much with.

I have a couple of similar configs using 7i44 + 7i49 so should be able to help.
Here is an example to study, from my lathe.
Note the the config can be very simple if the resolver is aligned to the motor and has the same number of poles, (The Z axis) and in that case you can connect resolver.angle directly to 8i20.angle.
Things are rather less simple on the X axis, which is an 8 pole motor and single-pole resolver, and this requires the bldc component to recalculate the angle. The scale is always the same for any 7i49, but the offset will need to be found by experiment / guesswork. If the motor runs at the same speed in both directions it is a good sign that the offset is right, or close enough. It will be a number between 0 and +/- the scale.

Hi again!
At last I got to this project!
But I got a problem, what type of linuxcnc I should install to work with 7I93 card?
I found an instruction here :
forum.linuxcnc.org/9-installing-linuxcnc...iest-install?start=0
and here:
linuxcnc.org/docs/html/getting-started/g...th_preempt_rt_kernel
but terminal commands doesnt work. Is some other version of linuxcnc for these ethernet cards, or some other repository for packages ?
