I can't answer - I don't know from your description and filename what was in 1) the coordinte file you input to the EM grompp, 2) the .gro file you got out of EM mdrun (which presumably went into the NPT grompp), 3) the .tpr file you got out of NPT grompp, and 4) the .gro file you got out of NPT mdrun (which will always have velocities regardless of the foregoing) Please respect your reader's time and describe your observations carefully :-) I think there should never be velocities in 2. Velocities in 3 should follow what the .mdp file said (but if 2 wrote velocities, then it is conceivable that those are still the velocities in 3 iff gen_vel=no, but you would have to inspect the values with gmxdump to see what was happening).
