Parameter Setting for Setting a Live-Tool Maximum Speed

Hey all-

I have a Fanuc 18i-tb control on a Hyundai-Kia SKT210sy CNC Turning Center. The data printed on the live-tool blocks say they will
run at 5000 rpm but I can't seem to get them to turn any faster then 2500 rpm. Parameter setting? Not that I want to run much faster
then 2500 rpm on these blocks but I do want to know how to get up there for short periods when necessary.

Any help from frey is greatly appreciated!
