    • PURPOSE:To ensure the highly accurate control with no shock for a moving machine having a backlash, by adding a function to obtain a boundary line with which the desired time is shifted on the position and speed phase surfaces from the changing point of acceleration and deceleration and then performs a gap control with the boundary line used as the boundary conditions. CONSTITUTION:When a gap due to a backlash is set at the acceleration side during a start, switch devices 14 and 15 are switched toward 14b and 15b by a deciding device 13. Thus the acceleration is controlled for a motor M. Then the device 15 is switched to a switch 15a to perform the deceleration control. Thus the gap is set at 0. When the device 15 is switched to a switch 15b, the motor M receives the acceleration control. Then the position and speed reach the value on an auxiliary switch curve with which the time is shifted early. Thus the position and speed are switched to perform the deceleration control. When the position and speed coincide with the value on the switch curve, the acceleration control is perfomed to set the gap of the deceleration side at 0. At this time point, the device 14 is switched to continue the deceleration control up to the target value.
    • 目的:为了确保对具有间隙的移动机器没有冲击的高精度控制,通过增加功能来获得在加速和减速的变化点的位置和速度相位表面上期望的时间偏移的边界线 然后用作为边界条件的边界线进行间隙控制。 构成:在启动期间由于间隙在加速侧设定间隙时,开关装置14,15由决定装置13切换为14b,15b。因此,对马达M控制加速度。然后,装置15 切换到开关15a以进行减速控制。 因此间隙设定为0.当装置15切换到开关15b时,马达M接收加速度控制。 然后,位置和速度达到辅助开关曲线上的时间早到的值。 因此,切换位置和速度以执行减速控制。 当位置和速度与开关曲线上的值一致时,执行加速控制以将减速侧的间隙设定为0.在该时间点,切换装置14以将减速控制继续到目标值 。
