The maximum velocity that can be tracked depends on the specific module. Please refer to the specification of your module. The velocity output (the digital word) represents a percentage of full scale where full scale is determined by the velocity scale (when the scaling can be adjusted by the user). The scaling feature (Velocity Scale Factor register) allows a user to rescale the digital velocity output word for a lower expected maximum rotation of the UUT. This, sets the full-scale output closer to what the actual device maximum rotation would be, resulting in better resolution. The scaling factor is a mathematical application after the conversion. It changes the digital output word resolution only. It does not affect accuracy.
