本安全功能应用说明书介绍了如何对 Compact GuardLogix®控制器和POINT Guard I/O模块进行接线、配置和编程，从而将其连接到 PowerFlex™ 750 安全速度监视选件(-S1) 模块，执行安全速度功能。必须要注意的是，安全速度模块才是执行本操作说明书中所述的零速度、安全限速和安全方向等安全功能的真正模块。只有在执行零速度和安全限速 (SLS) 安全功能时才需要用到 GuardLogix 安全控制器。例如，转动 SLS钥匙开关时，连接到 PowerFlex 755 SLS 输入的 GuardLogix 输出将通电，请求安全限速。注意，安全方向在安全速度模块中进行配置，且始终受到监视。GuardLogix 控制器与安全方向安全功能之间没有任何联系。
安全功能的执行单元为安全速度模块的嵌入式安全断开扭矩功能 (STO) 通道。如果PowerFlex 755 STO 输入断电，则由 PowerFlex 755 变频器控制的电机将滑行停止。
本例中使用 Compact GuardLogix 控制器，但对任何 GuardLogix 控制器都适用。
本例中假定使用两个不同的增量式编码器；一个是 845H，一个是 845T，它们连接到PowerFlex 750 通用反馈选件模块，由安全速度模块进行监控。使用的控制器默认平均无危险故障时间 (MTTFd) 可达 10 年 (根据 ISO-13849)。使用 DC Measures 的SISTEMA 库，可达到 99% 的诊断覆盖率。DC 基于冗余 (两个编码器)、多样性 (两种编码器类型)、诊断 (编码器信号交叉监控) 和各编码器独立的电源。

Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
