无需新增孔位的无电压释放与紧急停止方案？No-volt release with few new holes?
➀ 本文探讨了在CNC车床项目中实现无电压释放和紧急停止系统的需求，同时尽可能减少前面板新增开孔；
➁ 现有前面板按钮通过12V电源控制主轴电机和步进电机的继电器，但当前紧急停止按钮因无钥匙而需更换；
➂ 考虑采用LA38等开关方案，权衡安全性与面板改造，并建议为主轴和步进电机设计独立控制。
➀ The article discusses the need to implement a no-volt release and emergency stop system for a CNC lathe project while minimizing new holes in the front panel;
➀ Existing front panel buttons use a 12V power supply to control relays for spindle and stepper motors, with the current emergency stop lacking a key;
➁ Options for alternative switches (e.g., LA38 series) are considered, balancing safety requirements and panel modifications, including separate controls for spindle and stepper motors.
