立式加工中心电源的安装与一般机床电源的安装有所不同。数控机床NC要求电源电压稳定,避免各种电磁干扰,还由于NC系统电压只有5V,控制电压也只有12V、15V、24V几种,如果三相电源严重不平衡,或因为某种原因漏电比较严重,那么中性线N上将有较高的电位,这将影响NC系统和控制电路正常工作,甚至会发生NC电路烧毁事故。为使立式加工中心等数控机床安全运行,我认为在立式加工中心电源安装时应注意以下几点:
Vertical machining center power supply installation and general machine power supply is different. CNC machine NC requires stable power supply voltage, to avoid a variety of electromagnetic interference, but also because the voltage of the NC system is only 5V, the control voltage is only 12V, 15V, 24V several, if the three-phase power serious imbalance, or for some reason more serious leakage , Then neutral N will have a higher potential, which will affect the normal operation of the NC system and control circuit, or even NC circuit burned accident. In order to make vertical machining centers and other CNC machine tools safe operation, I think the vertical machining center power supply installation should pay attention to the following points:
