There is no analog input on the 7I95/7I95T so maybe an
encoder would make more sense for feed rate override.
You could use either one of the high speed encoders or
one of the 4 MPG encoders built into the isolated I/O.
Note the both MesaCT and the very latest pncconf
( in LinuxCNC master ) can make configurations for the
7I95/7I95T.
