1391-DES45-DI数字交流伺服驱动器
保护I/O信号免受噪声影响-布线时，将交流I/O信号线与直流I/O信号线隔离。如果这不可行，则为每组信号线使用集体屏蔽线布线时，将承载较大电流的信号线与其他信号线隔离。如果这不可行，则对承载大电流的信号线使用屏蔽线如果任何电感负载要连接到FA-M3的输入或输出端子，请在负载附近安装浪涌保护器或二极管。有关更多详细信息，请参阅第A3.6.4小节“连接输入设备”或第A3.6.5小节“连接输出设备”中的“感应负载对策”。注意，当FA-M3在雷电频率较高的地区使用时，请安装保护设备，如电涌放电器重新检查电源模块的I/O规格。具体而言，请注意，将交流电源连接到需要直流输入的电源模块，并将200-240V交流电源连接至需要100-120V交流输入的电源设备模块，都会导致机器故障为避免触电，接线前请关闭电源确保直流输入电源模块的“+”、“–”和FG端子以及交流输入电源模块中的L、N和FG接线端正确连接。端子螺钉和压接端子F3PU-0S电源模块使用M4螺钉接线板，而F3PU-0N电源模块使用M3.5螺钉接线板。
接地程序
当FA-M3安装到基本模块上时，它会自动与基本模块的金属底盘接触，因此它与控制器的信号电位和控制器的信号接地共用相同的电位。使用横截面积超过2mm2的电线，通过尽可能短的路线连接到保护接地（符合每个国家的法规）。有关FA-M3接地线的详细信息，请参阅第A3.3.2小节，与电源模块内噪声滤波器的中性端子相连。LG端子接地可适当衰减电源的共模噪声。如果LG端子打开，噪声滤波器的效果将降低。交流电源模块需要保护接地。直流电源模块需要保护接地或功能接地。当构建符合CE标记的系统时，将LG端子连接到FG端子，并使用编织线或其他电线将这些端子接地，以确保即使在高频下也具有低阻抗。注意：当LG端子未连接到FG端子时，LG端子具有输入电源电压的一半电势。重新检查输入/输出模块的I/O规格。请注意，施加超过输入模块最大允许输入电压或电流的电压或电流，或施加超过输出模块最大开关容量的电压或电压或电流将导致机器故障、物理损坏或火灾危险为避免触电，接线前请关闭电源确保电源端子的极性正确。
Protecting I/O Signals against Noise
- Segregate the AC I/O signal lines from DC I/O signal lines when routing them. If this is not feasible, use collectively shielded lines for each group of these signal lines. - Segregate signal lines carrying larger current from other signal lines when routing them. If this is not feasible, use shielded lines for signal lines carrying large current. - If any inductive load is to be connected to an input or output terminal of the FA-M3, install a surge protector or a diode near the load. For further details, see “Inductive Load Countermeasures,” in subsection A3.6.4, “Connecting Input Devices” or “Inductive Load Countermeasures,” in subsection A3.6.5, “Connecting Output Devices.” CAUTION Install a protective device, such as a surge arrester, when the FA-M3 is to be used in a district with a high frequency of thunder.- Re-check the I/O specifications for the power supply module. Specifically, note that connecting an AC power supply to a power supply module requiring DC input and connecting a 200-240V AC power supply to a power supply module requiring 100- 120V AC input will lead to machine failure. - To avoid electrical shock, turn off the power before wiring. - Make sure that the ‘+’ , ‘–’ and FG terminals of a DC input power supply module and the L, N and FG terminals of an AC input power supply module are connected correctly.Terminal Screws and Crimp-on Terminals The F3PU-0S power supply modules use M4-screw terminal blocks, unlike F3PU-0N power supply modules, which use M3.5-screw terminal blocks.
Grounding Procedure
It is automatically brought into contact with the metal chassis of the base module when the FA-M3 is mounted onto the base module so it shares the same electric potential with the controller’s signal potential with the controller’s signal ground. Using a wire with a cross-section area of more than 2mm2 , connect to the Protective earth (Comply with the regulation of each country.) by taking the shortest route possible. For details onthe grounding lines of the FA-M3, see subsection A3.3.2, Is connected with the neutral terminal of the noise filter within the power supply module. Grounding the LG terminal properly attenuates the comon mode noise from the power supply. If the LG terminal is opened, the effect of the noise filter will be reduced.AC power supply module is required protective earth. DC power supply module is required protective earth or functional earth. When building a system compliant to CE Marking, connect LG terminal to FG terminal and ground these terminals with braided or other wires that ensure low impedance even at high frequencies. CAUTION LG terminal has a half potential of the input power supply voltage when LG terminal isn’t connected to FG terminal.Re-check the I/O specifications for the input/output modules. Note that applying a voltage or current that exceeds the maximum permissible input voltage or current of an input module or a voltage or current that exceeds the maximum switching capacity of an output module will lead to machine failure, physical damage or fire hazard. - To avoid electrical shock, turn off the power before wiring. - Make sure that the polarity of power terminals is correct.
