Assuming that by "Input voltage" you meant Vbus voltage, then I believe that what you have described above is the voltage mode, not the %Vbus mode. Someone please correct me if I'm wrong.

The %Vbus mode simply takes the command and interprets it as a % PWM.

With brushed DC motors (I'm sure there are other motor types as well, but BLDC motors are all that FRC teams need to be concerned with)

"BLDC" is an acronym for brushless DC.
