浅谈数控冲床的输入/输出接口
 

输入输出信号是CNC系统与外界交换的信息,其接口是交换信息的必要手段,在CNC数控系统中占有重要的位景。对CNC装置来说,由机床向CNC传送的信号称为输入信号,而出CNC向机床传送的信号称为输出信号。


The input and output signal is the information exchange between CNC system and the outside world. The interface is the necessary means to exchange information, and has an important position in the CNC numerical control system. For the CNC device, the signal transmitted from the machine to the CNC is called the input signal, and the signal that the CNC sends to the machine is called the output signal.


不同的输入/输出设备与CNC系统相联接,采用与其 相应的I/O接口电路和接口芯片。接口芯片一般分为专用芯片和通用芯片。前者专门用于特殊的输入/输出设备的接口,后者适用于多种设备的接口对数控装置而言,主要交换的信号包括交流数字输入/输出信号、直流模拟I/O信号和交流l/O信号。注册食品公司


Different input / output devices are connected to the CNC system, and the corresponding I/O interface circuit and the interface chip are adopted. Interface chip is generally divided into special chip and general chip. The former dedicated to special input / output device interface, the latter applies in a variety of equipment interface for CNC device, main switching signal including AC digital input / output signal and DC AC I / O and I / O signal simulation.
