PURPOSE:To improve follow-up performance of digital servo controller regardless of the operating condition. CONSTITUTION:Proportional gain and integrating time of proportional/ integrating operation are set in speed feedback loop according to the servo lock state, accelerating/decelerating state or constant speed state of a commanded control shaft. Thus set proportional gain and integrating time are applied to the speed difference between a target speed and a current speed and the time integration thereof, thus operating a target current for current feedback loop through proportional/integrating operation. Consequently, vibration is prevented under servo lock state and overshoot is prevented at the time of transfer to constant speed. |
