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。
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system
