The apparatus further comprises a first control circuit connected to receive first reference signals of a predetermined frequency and control the rotation of the motor according to the first reference signals, a second control circuit connected to receive second reference signals and control the rotation of the motor according to the second reference signals, and a switching circuit for connecting the first and second control circuits alternatively to the motor.Other References
