CONTROLLER FOR DIGITAL SERVO

摘要

PURPOSE:To provide a digital servo controller which both improves a mechanical processing accuracy of a controlled object and shortens a processing time. CONSTITUTION:A speed command to be calculated and output by a position loop 2 is so switched by a changeover switch 23 as to be output from a constant time accelerating/decelerating block 21 when a control target speed is lower than a predetermined switching level and from a constant acceleration accelerating/decelerating block 22 when the control target speed is faster than a predetermined switching level. Thus, a mechanical vibration of a control object is suppressed in a low speed range to improve a mechanical processing accuracy, and a control processing time is shortened in a high speed range.
