Abstract
A controller for use in a vibratory work machine may include a vibratory frequency selection system having a user interface with a discrete amplitude selection input device and a discrete frequency selection input device. The controller may receive a frequency selection signal from the frequency input device and generate a frequency control signal having a characteristic corresponding to the frequency setting of the input device. The controller may also receive an amplitude selection signal from the amplitude input device and output at least the frequency control signal to cause a vibrator mechanism of the machine to generate vibrations having a frequency and amplitude corresponding to the settings of the input devices.
