PURPOSE:To perform control of rotary speed with high resolution through an inexpensive general use microprocessor by transmitting drive data through an address bus and a data bus. CONSTITUTION:Drive data are transmitted from a microprocessor 1 through on address bus AB and a data bus DB to a D/A converting circuit 2 so as to produce an analog voltage based on combined data. A V/F converting circuit 3 generates drive signals comprising pulse train having frequency corresponding to the analog voltage, then a motor 5 is controlled through a driver circuit 4 based on the drive signal. |
