    • A numerical control device for synchronously controlling the movement of a plurality of axes of a machine by repeatedly controlling a cyclic motion. An axis of the machine is designed to stop at a predetermined position upon the occurrence of an emergency stop. To achieve this stop position, an amount of retraction is set up to a position where a tool of machine does not interfere with a work piece or other obstacles. When an emergency stop signal is entered during a binary operation, because of an occurrence of an abnormality, a movement control amount for each period, corresponding to a set amount of retraction, is added to the movement control amount for each period of the binary operation and the axis is thereby driven by the resultant modified movement control amount. The binary operation is stopped upon the reaching of the stop position, and the tool can be held at this retracted position, by the set amount of retraction. Thus, the tool can be retraced to a predetermined position where it does not interfere with either a work piece or another obstacle.
    • 一种用于通过重复地控制循环运动来同步地控制机器的多个轴的运动的数字控制装置。 机器的轴线被设计成在发生紧急停止时停止在预定位置。 为了达到这个停止位置,将一定数量的退回设置到机器的工具不干扰工件或其它障碍物的位置。 当在二进制操作期间输入紧急停止信号时,由于发生异常,对于每个周期的移动控制量,相应于设定的撤回量,对于二进制运算的每个周期的移动控制量, 并且由此由所得到的改进移动控制量驱动该轴。 二进制操作在到达停止位置时停止,并且可以将工具保持在该缩回位置,设定回缩量。 因此,可以将工具回溯到不干扰工件或其他障碍物的预定位置。
