I'm wondering if it's ok to send the analog
output of a drive (speed, 0-10V) to two
different PLC analog input card?

Hi,
This used to be fairly standard on production lines, where the filler 0-10v was used by all the downstream equipment, (nowadays the synchronisation is usually done with much more civilised digital protocols). I expect the only concerns would be that the various inputs and outputs are either galvanically isolated, or in reference to the same 0v.

Should be OK, unless the inputs
have very low impedance. In many
applications, like conveyors, the
0-10 V signal may go to many
places to synchronize speeds.
Unless the run is very short you
should shield it.
