    Patent number: 5561355
    Abstract: A positional deviation reading sampler reads or samples a positional deviation between a target position inputted from an external device and an actual position of a motor. A position control calculator converts the positional deviation into a speed command. A speed control calculator receives a speed deviation between the speed command and an actual speed, and converts this speed deviation into a torque command to drive the motor. The position control calculator, having a function of switching a sampling interval in accordance with a level of the positional deviation, determines an optimum sampling interval for the positional deviation reading sampler. The speed control calculator performs the open-or-close control of the sampler in such a manner that the sampling interval of the positional deviation reading sampler is reduced with reducing positional deviation.
