You just need a VFD of the correct power for the motor. And, assuming you are talking of manual setting of speed, you need a potentiometer with a knob to adjust it, and connect it to the appropriate VFD inputs. The VFD will also need to be programmed to suit this and this varies in detail, depending on manufacturer.

For example, with a 60 Hz maximum frequency and 1:40 control range, a drive using the V/f control method can control a motor all the way down to 1.5 Hz.
