摘要
介绍了西门子840D SL数控系统外部触发的安全集成功能的基本知识和双通道概念。对其硬件单元Profisafe模块和S120驱动系统的功能描述、信号接入进行说明,利用框架流程图简介系统如何实现机床的安全集成功能。列举具体加工中心案例,设计机床应用外部触发的安全集成功能的实现步骤:硬件配置、参数说明、PLC与NC的SPL安全程序编程。
The article introduces the basic knowledge safety-integrated function which is triggered by external elements in and doubt-channel conception of Siemens 840D SL CNC system. Explain the function description and signal access of the hardware modules including profisafe modules and S120 drive system modules, the frame flow chart is used to show how the system achieves the safety-integrated function on machine tool. List the specific machining center case , then design the steps for applying the extern-triggered safety-integrated function on the machining center： hardware configuration, parameter description, programming of PLC and NC SPL safety programs.
