Universal Driver

I have a TPS 5100-1 version 3.3 console. The maximum rpm I get when I attach the universal driver is 1500 but in the manual it shows upto 75000. Also the ream rpm is set at 600. So is it the same in all tps system or can the rpm be increased for the universal drive in drill mode and ream mode . I do get 75000 in the saw mode
