A control apparatus for a vibration driven motor, which obtains a driving force by forming a vibration wave upon application of a frequency signal to electro-mechanical converting elements. The control apparatus includes a pulse oscillation circuit, a counter for counting pulses from the pulse oscillation circuit, and a data set circuit for setting numerical value data. Every time the count value of the counter coincides with the data set in the set circuit, an output is generated, and the control circuit controls the frequency of the frequency signal according to the frequency of the generated output.
