控制驱动进给轴的伺服电动机的伺服电动机控制装置
摘要：
一种控制驱动进给轴的伺服电动机的伺服电动机控制装置。运算系数设定部，把反馈控制用运算系数设定为为切削进给动作而设定的第一反馈控制用运算系数值和比第一反馈控制用运算系数值小的快速进给动作用的第二反馈控制用运算系数值之间的值。运算系数变更部，在作为快速进给动作中的任意时刻的第一时刻预测在第一时刻后的第二时刻动作指令从快速进给动作指令向切削进给动作指令切换的情况下，经过第一时刻和第二时刻之间的第一期间或者在第一时刻后而且在第二时刻前的第三时刻和第二时刻之间的第二期间，把反馈控制用运算系数从第二反馈控制用运算系数值连续变更为第一反馈控制用运算系数值。
摘要（英）：

The invention relates to a servo motor control device for controlling a servo motor configured to drive a feed shaft. An arithmetic coefficient setting unit sets a feedback control arithmetic coefficient to a value between a first feedback control arithmetic coefficient value for a cutting-feed and a second feedback control arithmetic coefficient value for a rapid-traverse operation smaller than the first feedback control arithmetic coefficient value. An arithmetic coefficient change unit continuously changes the feedback control arithmetic coefficient from the second feedback control arithmetic coefficient value to the first feedback control arithmetic coefficient value over a first period between a first time, which is an arbitrary time during the rapid-traverse operation, and the second time after the first time or a second period between a third time after the first time and before the second time, and the second time if it is predicted at the first time that the operating command switches from the rapid-traverse operation command to the cutting-feed command at the second time.
