What board do you recommend for pull/dir for a T3D servo drive?

I have T3D servo motors and a 7i97t board but it seems that it is not compatible. Which board would you recommend for 5 or 6 of these servo motors?

The T3D drive has an analog input option but no encoder output
(which is a bit uncommon) so will not work with the 7I97/7I97T.

A step/dir board would be required, a Mesa 7I96,7I96S or 7I76EU
are possibilities.

You might still use it, if there is firmware that puts the stepgens on the IDC26 connector and use a cheap BOB to wire in the drives. Requires also an DB25 to IDC26 cable, so all cheap stuff, but be warned that cheap BOB might limit the step frequency a lot.
You can just wire drives directly to IDC26, but that does require caution in proper wiring as those I/O pins are highly sensitive. Having said that, i use those pins on plasma machines and never ever had any die.
But if you still want to get a new board, get the 7i96S as it can be found easily and can be expanded easily by adding, say a 7i84 for 32 more inputs and 16 more outputs, and say a 7i85 for more encoders and more boards like 7i84 or 7i70 or 7i71 or....

Yes, there is 7I97T firmware for running the common "Mach 5 Axis"
step/dir breakout board:

7i97t_5abobd.bin
 

What bob do you recommend me?

do you need a bob to use it?

This means no BOB.

the breackout board need protection?

thank you for you answer

the pinout or configuration to connect the step and dir where could I find it?

 Is the common breakout I recommend.

You can connect directly to the parallel expansion connector but one wiring mistake
and you may kill the 7I97T

You can check the (DB25) pinout with mesaflash's --readhmid command if you have loaded the
desired firmware into the 7I97T.  You can also check the .pin files in the 7I97t.zip support image.
These are just the result of running mesaflash with the --readhmid option on a 7I97T with the
corresponding firmware loaded.

If you download the latest mesaflash, it has the option of showing the HDR26 pinout (the normal default
is to show the DB25 pinout)
