IS200BPIIH1AA工控备件机器人模块
分析电机电流特征，并基于预设算法确定电机中何时出现转子棒断裂。通过完全可编程的警报，转子断条功能将提供对任何转子问题的早期检测，并向维护人员建议即将发生的问题，以便对电机进行预测性维护，防止电机发生灾难性故障。通过提供潜在转子问题的早期指示，可以避免严重的系统问题，例如：启动扭矩降低、过载、扭矩和速度振荡以及轴承磨损。借助先进的转子断条检测系统，对即将发生的问题发出高级警告可减少灾难性故障，最大限度地延长电机寿命和系统正常运行时间。模拟模拟功能测试功能和继电器对编程条件的响应，无需外部输入。当置于模拟模式时，469暂停读取实际输入并用模拟值替换它们。可以模拟跳闸前和故障条件，为每个状态配置电流、电压、系统频率、RTD温度和模拟输入。用户界面键盘和显示器469有一个键盘和40个字符的显示器，用于本地监控和继电器配置，无需计算机。不活动时最多可显示20条用户选择的默认消息。如果发生跳闸、报警或启动块，显示屏将自动默认为相关信息，信息LED指示灯将闪烁。LED指示灯469前面板上有22个LED指示灯。这些可快速指示469状态、电机状态和输出继电器状态。通信469配备了三个标准串行通信端口，一个RS232位于前面板，便于故障排除和编程，两个RS485位于继电器后部。可选的10BaseT以太网和DeviceNet端口也可用。后部RS485端口提供与DCS、SCADA或PLC的远程通信或连接。RS232和RS485端口支持300至19200 bps的用户可编程波特率。可选以太网端口可用于连接469至10 Mbps以太网网络。三个串行端口支持ModBus®RTU协议，而以太网端口通过TCP/IP协议支持ModBus™RTU。469的通信系统设计为允许通过所有端口同时通信。使用以太网作为物理介质将469集成到局域网或广域网，取代了多点有线网络（例如串行Modbus®），并消除了昂贵的租用或拨号连接，降低了每月的运营成本。EnerVista软件
analyzes the motor current signature and based on preset algorithms will determine when a broken rotor bar is present in the motor. With fully programmable alarms, the broken rotor bar function will provide early detection of any rotor problems and advise maintenance personnel of the impending issue allowing for predictive maintenance of the motor and prevention of catastrophic motor failures. By providing early indication of potential rotor problems, serious system issues such as: reduced starting torque, overloads, torque and speed oscillation and bearing wear can be avoided. With the advanced broken rotor bar detection system, advanced warning of impending problems reduces catastrophic failures, maximizing motor life and system uptime. Simulation The simulation feature tests the functionality and relay response to programmed conditions without the need for external inputs. When placed in simulation mode the 469 suspends reading of the actual inputs and substitutes them with the simulated values. Pre-trip and fault conditions can be simulated, with currents, voltages, system frequency, RTD temperatures, and analog inputs configured for each state. User Interfaces Keypad and Display The 469 has a keypad and 40 character display for local monitoring and relay configuration without the need for a computer. Up to 20 user-selected default messages can be displayed when inactive. In the event of a trip, alarm, or start block, the display will automatically default to the pertinent message and the Message LED indicator will flash. LED Indicators The 469 has 22 LED indicators on the front panel. These give a quick indication of 469 status, motor status, and output relay status. Communications The 469 is equipped with three standard serial communications ports, one RS232 located in the front panel for easy troubleshooting and programming, and two RS485 in the rear of the relay. Optional 10BaseT Ethernet and DeviceNet ports are also available. The rear RS485 ports provide remote communications or connection to a DCS, SCADA, or PLC. The RS232 and RS485 ports support user programmable baud rates from 300 to 19,200 bps. The optional Ethernet port can be used to connect the 469 to 10 Mbps Ethernet networks. The three serial ports support ModBus® RTU protocol, while the Ethernet port supports ModBus® RTU via TCP/IP protocol. The communication system of the 469 is designed to allow simultaneous communication via all ports. Using Ethernet as the physical media to integrate the 469 to Local or Wide Area Networks, replaces a multidrop-wired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing monthly operating costs.
