    • A capacitor (114) is provided between a power supply line (111a) and a ground line (111b), which connect a power supply connector (130) connected to a high voltage power supply (140) and a power element (118). A current detection unit (113) for detecting positive current flowing in the direction from the high voltage power supply (140) to the power element (118) and negative current flowing in the opposite direction is provided on the power supply line (111a). A load resistor (112) is provided between the current detection unit (113) and the power supply connector (130). When the current value detected by the current detection unit (113) becomes less than zero, a control unit (116) detects that the connection of the high voltage power supply (140) has released.

    • Even in an uncuttable state in which an actual rotational direction of a main spindle is not matched with an actually cuttable main spindle rotational direction of a tool, an interference check between a workpiece and the tool is performed. Accordingly, the cuttable main spindle rotational direction of the selected tool or the uncuttable main spindle rotational direction is compared with each main spindle rotational direction of a working machine during execution of a simulation, and it is determined whether an interference check between the tool blade edge and the workpiece is necessary on the basis of the comparison result. When it is determined that the interference check is not necessary in the step above, the interference check between the tool blade edge and the workpiece is not performed. When it is determined that the interference check is necessary, the interference check between the tool blade edge and the workpiece is performed. When the interference therebetween is present, abnormality is detected.
    • 即使在主轴的实际旋转方向与工具的实际可切削主轴旋转方向不匹配的不切割状态下,也能够进行工件与工具之间的干涉检查。 因此,在执行模拟期间,将所选择的工具的可切割的主轴旋转方向或不可切削的主轴旋转方向与作业机械的主主轴旋转方向进行比较,并且确定工具刀刃之间的干涉检查 并且在比较结果的基础上需要工件。 当在上述步骤中确定不需要干涉检查时,不执行刀片刃与工件之间的干涉检查。 当确定需要进行干涉检查时,执行刀片刃和工件之间的干涉检查。 当存在它们之间的干扰时,检测到异常。

    • A numerical control system improves safety when asynchronously operating systems are operated as a single control unit. A machine control system outputs a command generated by interpreting a program with a command number assigned thereto, sends it to a collision detection system, and receives check result data therefrom, whereby when the number of commands for which check result data are obtained is more than or equal to a preset second threshold, a command number assigned to the check result data is output when it is determined that there is no probability of collision. When the result of a check on the probability of collision for a command received from a linkage data sending and receiving section is returned, the collision detection system returns check result data to the linkage data sending and receiving section by assigning a command number given to the checked command to the check result data.
    • 当异步操作系统作为单个控制单元运行时,数字控制系统可提高安全性。 机器控制系统输出通过解释具有分配给其的命令编号的程序而生成的命令,将其发送到冲突检测系统,并从其接收检查结果数据,由此当获得检查结果数据的命令数大于 或等于预设的第二阈值时,当确定不存在碰撞的可能性时,输出分配给检查结果数据的命令号。 当返回对从连接数据发送接收部接收到的命令的碰撞概率的检查结果时,碰撞检测系统通过分配给连接数据发送接收部的命令号码将检查结果数据返回给联动数据收发部 检查命令到检查结果数据。

    • An object of the invention is to provide a memory control unit and a memory control method capable of making the operation setting of SDRAM without intentionally stopping access to the SDRAM.A switch signal generation section (18) for generating a switch signal to switch the operation setting of SDRAM (200), a switch control section (16) for switching the operation setting of the SDRAM (200) using a switch setup value (17) as the switch signal is output from the switch signal generation section (18), and an access control section (14) for suppressing acceptance of an access request to the SDRAM (200) in the time period from the switch start time of the operation setting to the switch completion time are provided. Accordingly, when the operation setting of the SDRAM (200) is changed, it is not necessary to intentionally stop access to the SDRAM (200) and it is made possible to change the operation setting of the SDRAM (200) without being affected by the access situation to the SDRAM (200).
