例一CNC系统加不上电一台数控淬火机床，数控系统采用西门子公司的SINUMERIK810系统。当按下CNC启动按钮时，系统开始自检，在显示器上出现基本画面时，数控系统马上掉电。分析故障原因，可能与CNC系统24V供电电源有关，当24V直流电源电压幅值下降到一定数值时，CNC系统采取保?
Example of a CNC system plus power on a CNC quenching machine, CNC system using Siemens SINUMERIK810 system. When you press the CNC start button, the system starts a self-test and when the basic screen appears on the display, the CNC is powered down immediately. Analysis of the cause of the malfunction may be related to the 24V power supply of the CNC system. When the amplitude of the 24V DC power supply voltage drops to a certain value, the CNC system adopts the warranty
