How to convert a pump's RPM to Hz for a Powerflex 40 drive?

If I know what RPM a viking internal gear pump needs to run at, how do I determine what the Hz is for the Allen Bradley Powerflex 40 drive that is running it?

Look at the motor nameplate Hz and RPM. Needed Hz = Nameplate Hz x Needed RPM / Nameplate RPM.

If you know the speed of the pump for operation across the line, use Needed Hz = Line Hz x Needed RPM / Line Hz Speed.

What about the gearing ratio? If you know how to account for it, divide Hertz by 60 to get RPM assuming that each Hertz accounts for one rotation.
