    • A positioning control unit in which a motion control unit receives a start signal for a motion program outputted from a sequence control section and transmits a drive signal to a servo amplifier according to the operational contents indicated in the motion program. The servo amplifier transmits a control signal to a servo motor according to the drive signal and provides controls over the servo motor. The motion control section stores a start signal in an interface section when it receives a start signal for a motion program to be executed next from the sequence control section during operation of the motion program, and executes the motion program indicated by the start signal after the operation of the motion program in operation is completed.
    • 一种定位控制单元,其中运动控制单元接收从顺序控制部分输出的运动程序的起始信号,并根据运动程序中指示的操作内容将驱动信号发送到伺服放大器。 伺服放大器根据驱动信号向伺服电机发送控制信号,并提供对伺服电机的控制。 运动控制部分在运动程序运行期间接收到从顺序控制部分接下来要执行的运动程序的起始信号时,将接收部分中的开始信号存储起来,并且执行运动程序之后由起始信号指示的运动程序 运行程序的运行完成。

    • A method of controlling the positioning of a rotor of a stepping motor is disclosed. During the last step in a movement of the rotor to a desired rest position thereof, the windings of the stepping motor are energized so as to produce a first magnetic vector, a position indicated by the first magnetic vector being displaced from the desired rest position in the direction of the movement of the rotor by a predetermined amount. This displacement of the first magnetic vector causes the rotor to overshoot the desired rest position by such an amount that a positioning error of the rotor due to a hysteresis characteristic of the rotor in the direction of the movement thereof is compensated. The windings are then energized to produce a second magnetic vector with the position indicated by this second magnetic vector coinciding with the desired rest position of the rotor. The energization of the windings may be performed in small steps to effect a vernier driving of the rotor.
    • 公开了一种控制步进电机转子定位的方法。 在将转子运动到其期望的静止位置的最后步骤中,步进电动机的绕组被通电以产生第一磁矢量,由第一磁矢量指示的位置从期望的静止位置偏移 转子的移动方向预定量。 第一磁矢量的这种位移使得转子超过期望的静止位置,使得由于转子在其运动方向上的滞后特性而导致的转子的定位误差得到补偿。 然后绕组被通电以产生第二磁矢量,其中由该第二磁矢量指示的位置与转子的期望的静止位置重合。 可以以小的步骤执行绕组的通电以实现转子的游标驱动。
