PROBLEM TO BE SOLVED: To reduce the cost and enable complicated motor control. SOLUTION: A motor control circuit has a pulse generating counter 110 which counts clock signals to obtain control pulses, a counter 113, etc., which count the control pulses, a rate data conversion ROM 103 which converts revolution data into count values, rate registers 104 and 105 which hold information concerning the upper limit and lower limit of the revolution, an acceleration/ deceleration interval registers 122 and 123 which hold information concerning the acceleration/deceleration, and a revolution data counter 107 which increases/ decreases the revolution data between the upper limit and lower limit of the revolution. In accordance with predetermined commands transmitted from a main control unit 1, instructions of re-writing of the various values and operation start/stop are issued by the motor control circuit. |
