    • First ends of electrical elements (CR18, CR14, CR17, CR16) forming safety circuits are electrically grounded, and safety circuits (switches 105, 103, 104, 107) are connected between the remaining second ends of the electrical elements and the power supply side (positive (+) side) of the system thereof, so that even if a signal transmitting line in the safety circuit system is grounded, the safety system relay is not excited; that is, it is kept opened, thereby to interrupt of the servo power supply circuit. Further, two relays of hardware system and of software system are provided which transmits an emergency stop state or other abnormal state to the outside. The relay contact means of the two relays are extended outside, so that it is detected with an external control board whether the relays are opened or closed, thereby to detect whether or not the contact means are fused.
    • 形成安全电路的电气元件(CR18,CR14,CR17,CR16)的第一端电接地,并且安全电路(开关105,103,104,107)连接在电气元件的剩余第二端和电源侧 (正(+)侧),使得即使安全电路系统中的信号传输线接地,安全系统继电器也不激励; 也就是说,它被保持打开,从而中断伺服电源电路。 此外,提供了两个硬件系统和软件系统的继电器,其将紧急停止状态或其他异常状态发送到外部。 两个继电器的继电器接触装置延伸到外部,从而通过外部控制板检测继电器是否被打开或关闭,从而检测接触装置是否熔断。
