Mesa cards are commercial.

linuxcnc.org/docs/devel/html/man/man9/hostmot2.9.html#BiSS
It looks like you have two channels of 750W and 2 channels of 4.75kW.
Neither the Mesa 8i20 or the STMBL are big enough to replace the 4.75kW drive if it does need to be that big. Both are rated at about 2.2kW, so might be able to run the motors, but perhaps not at original speeds.
The Fanuc hardware is pretty nice, it seems a shame not to use it. Does the controller power up?
Looking on eBay completed listings it looks like you might be able to get some money back for the Fanuc drives.

andypugh There is also a module for the Mesa cards that can read (at least some of) the Fanuc encoders.
dear andypugh is this some commercial product or is it something to build by your self?
Thanks

I now that the fanuc system is professional solution But even if is in running condition as i describe earlier there are some problems
first of all all the cables are cut in several places and from the time bin i don't have any electric schemes of the machine
second the machine have several switches and sensors in bad shape
third i don't now how i can find a running program and a post processor for that
To resume what is on the mane electric cabinet:
power supply 13.2 kw
servo amplifier 9,5kw it looks like 2 motors are connected on it
servo amplifier 4,75kw
servo amplifier 0,75kw
kind reminder the motors are 2.8kw

Well, the motor label seems to be inside the parameters of the STMBL, Mesa 8i20 or (Possibly, the rated voltage is a little high, the Pico brushless amp).
Is there a part number visible on the encoder housings?
Do you already have a LinuxCNC system? What hardware do you already own?
The first thing to try (I think) is to see if you can read position information from the motors.

i already check the pico system
there answer is
"Our servo drive is capable of producing up to 20 A peak.
The A06B-0143 motor has a stall rating of 15 A, but the peak
rating is 43 A. So, you could develop the continuous rating
of the motor with our servo amp, but less than half the peak
rating."
not very clear to me (limited knowledge)

It means that at the end you will have limited performance from the system. Probably not able to get the original acceleration provided by the fanuc servo drive.
Be aware that most of commercial (lower cost - not low cost) servo drives are not able to reach the 43A. The 20A from the pico servo drive is "standard" among many drives.
