PURPOSE:To largely shorten the entire moving time by shortening the time required for driving through up and throwdown and increasing the high speed synchronous drive range. CONSTITUTION:After a step motor 1 is accelerated at the maximum speed in a range that a stepout does not occur by the second drive pulse Q2, a speed regulation is performed to absorb the variations in the torque of the step motor by the second and third pulse rates are equivalently and the motor is then accelerated. Accordingly, the stepout due to the variations in the torque does not occur, and the motor 1 can be thrown up at a high speed. Since the pulse is applied in the reverse pattern to the case of the throwup after the application of the final synchronizing pulse to decelerate and stop the motor, the motor can be driven stably at a high speed even at the through down time. |
