No, what I meant is the feedrate will never go above the rapid speed, so if your motor tuning has a velocity of 2000mm/min you can never exceed that. If you call a G0 move it wil always be at rapid speed. If you call a G1 it will be at the F you have called. Setting the FRO will increase the feedrate so if you have a G1X100F80 and the FRO is at 300% your feed will be 240.
Hope you understand, I am not making a good job of explaining it LOL
