Step motor controller |
摘要 |
A step motor controller including a sampling program for sampling, at predetermined intervals, input target values that represent a position of the step motor. The difference between the sampled target value and a rotational position of the step motor is obtained. A step motor accelerating and decelerating program accelerates the step motor upon finding the difference between the sampled target value and the current position of the step motor is greater than a set value. When the difference is less than the set value the step motor is decelerated. The predetermined sampling time does not correspond to the natural frequency of the step motor system or to a period corresponding to a fractional multiple of the natural frequency.
