摘要： It takes a comparatively long time for a rotor of a stepping motor to be positioned at the next target stop position (target angular position) and stopped there. This time is the settling time. Before the rotor passes through the next target angular position and begins to oscillate, necessary control is provided to reduce the magnitude of the oscillation for the purpose of shortening the settling time. The phase excitation on each winding of the stepping motor is usually changed over successively until the target angular position is reached. When the stepping motor has approached the target angular position, the changeover of phase excitation is gradually conducted. As a result, the magnitude of the above described oscillation is reduced and hence the settling time is shortened.
摘要翻译： 步进电机的转子位于下一个目标停止位置（目标角度位置）需要比较长的时间，并停在那里。 这一次是定居时间。 在转子通过下一个目标角位置并开始振荡之前，提供必要的控制以减小振荡的幅度，以缩短稳定时间。 步进电动机的每个绕组上的相位激励通常连续地改变，直到到达目标角位置。 当步进电机接近目标角位置时，相位激励的切换逐渐进行。 结果，上述振荡的幅度减小，因此建立时间缩短。

摘要： In a sequence program constructed by forming a ladder diagram on a display screen, an element corresponding to a minimum unit of the ladder diagram is arranged by a symbol element and a character element. Inputting and amending operations of the ladder diagram are performed by a first cursor for designating each element and a second cursor for designating the character element of the element designated by this first cursor.
