PURPOSE:To realize an operation at high speed and with resulting high acceleration deceleration, by calculating a speed pattern in which the minimum operating time can be obtained within a range where the effective torque of a motor goes less than rated torque based on the measured data of the torque of the motor, and controlling the motor based on the speed pattern. CONSTITUTION:The titled method is constituted in such a way that the speed and acceleration/deceleration (speed pattern) in which the minimum operating time within the range where the effective torque of the motor goes less than the rated torque can be obtained, are calculated, and the motor is controlled based on an obtained speed pattern. In such a way, since the driving of the motor is controlled by the speed pattern in which the minimum operating time can be obtained under a condition where the effective torque of the motor goes less than the rated torque at every operation, it is possible to always display the capability of the motor satisfactorily, and to operate the motor in the minimum time.
