Hi,
my setup is as follows:
7i43 + (P4 connector -> 7i52) + 2x 8i20 + 2 "old" servos with encoder + special firmware provided by PCW : svss6_6s.bit (thanks !)
Test with these servos allowed me to rotate but with anomalies......
I would now test 2 Servomac (servo with resolver Tamagawa Seiki)
adding a 7i49 (P3 connector of 7i43).
Be it a special firmware to manage this new configuration.

I think it would be custom firmware, yes. You need smart-serial and Resolver modules.
Which 7i43 do you have? It is even possible that the smaller (7i43-200) card might not haveroom for both modules.
Only PCW would know for sure.

Hi Andy,
thank you for your prompt response.
My 7i43 is : 7i43 -U -4- ROHS model with a Spartan XC3S400.

You could consider making your own firmware.
It isn't all that difficult.
wiki.linuxcnc.org/cgi-bin/wiki.pl?Editing_MESA_Bitfiles
wiki.linuxcnc.org/cgi-bin/wiki.pl?Editin...SA_Bitfiles_Spartan2
You then need to make a vhdl file with the pinout you need, by combining files like this:
git.linuxcnc.org/gitweb?p=hostmot2-firmw...c14d7131feff;hb=HEAD
Which is actually a custom firmware for my Harrison milling machine that has found its way into the repository. That runs a 7i49 and a 7i44 and so is very close to what you want, but it is for a 3-connector card one of which in my case has a 7i39 brushless motor drive on it.
For a 7i43 you would need to edit that file down to look more like a typical 7i43-400 pinout:
git.linuxcnc.org/gitweb?p=hostmot2-firmw...05298ae6379f;hb=HEAD
Which is a 7i49 + GPIO config.

Hi Andy,
Thank you for all those informations.
I think there is plenty to occupy hundreds of hours
Again thank you for all links.
