1391-DES45-DI數字交流伺服驅動(dòng)器
保護I/O信號免受噪聲影響-布線(xiàn)時(shí)，將交流I/O信號線(xiàn)與直流I/O信號線(xiàn)隔離。如果這不可行，則為每組信號線(xiàn)使用集體屏蔽線(xiàn)布線(xiàn)時(shí)，將承載較大電流的信號線(xiàn)與其他信號線(xiàn)隔離。如果這不可行，則對承載大電流的信號線(xiàn)使用屏蔽線(xiàn)如果任何電感負載要連接到FA-M3的輸入或輸出端子，請在負載附近安裝浪涌保護器或二極管。有關(guān)更多詳細信息，請參閱第A(yíng)3.6.4小節“連接輸入設備”或第A(yíng)3.6.5小節“連接輸出設備”中的“感應負載對策”。注意，當FA-M3在雷電頻率較高的地區使用時(shí)，請安裝保護設備，如電涌放電器重新檢查電源模塊的I/O規格。具體而言，請注意，將交流電源連接到需要直流輸入的電源模塊，并將200-240V交流電源連接至需要100-120V交流輸入的電源設備模塊，都會(huì )導致機器故障為避免觸電，接線(xiàn)前請關(guān)閉電源確保直流輸入電源模塊的“+”、“–”和FG端子以及交流輸入電源模塊中的L、N和FG接線(xiàn)端正確連接。端子螺釘和壓接端子F3PU-0S電源模塊使用M4螺釘接線(xiàn)板，而F3PU-0N電源模塊使用M3.5螺釘接線(xiàn)板。
接地程序
當FA-M3安裝到基本模塊上時(shí)，它會(huì )自動(dòng)與基本模塊的金屬底盤(pán)接觸，因此它與控制器的信號電位和控制器的信號接地共用相同的電位。使用橫截面積超過(guò)2mm2的電線(xiàn)，通過(guò)盡可能短的路線(xiàn)連接到保護接地（符合每個(gè)國家的法規）。有關(guān)FA-M3接地線(xiàn)的詳細信息，請參閱第A(yíng)3.3.2小節，與電源模塊內噪聲濾波器的中性端子相連。LG端子接地可適當衰減電源的共模噪聲。如果LG端子打開(kāi)，噪聲濾波器的效果將降低。交流電源模塊需要保護接地。直流電源模塊需要保護接地或功能接地。當構建符合CE標記的系統時(shí)，將LG端子連接到FG端子，并使用編織線(xiàn)或其他電線(xiàn)將這些端子接地，以確保即使在高頻下也具有低阻抗。注意：當LG端子未連接到FG端子時(shí)，LG端子具有輸入電源電壓的一半電勢。重新檢查輸入/輸出模塊的I/O規格。請注意，施加超過(guò)輸入模塊最大允許輸入電壓或電流的電壓或電流，或施加超過(guò)輸出模塊最大開(kāi)關(guān)容量的電壓或電壓或電流將導致機器故障、物理?yè)p壞或火災危險為避免觸電，接線(xiàn)前請關(guān)閉電源確保電源端子的極性正確。
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.
