HE693CBLSNP模块;HE693CBLSNP模块;HE693CBLSNP模块SIEMENS6SE3114维修实例故障现象：接通电源无反应，测560V直流电源正常，开关电源无输出。检查思路：该机采用UC3844作PWM调制，驱动大功率开关场效应管输出，查其退耦电容C56有轻微漏电，更换后试机一切正常。由于C56的漏电把UC3844的工作电源其中一部份旁路掉，并且供电限流电阻值较大（1M）UC3844无法达到启动阀值而误检测作欠压而不开机。普传5.5KW故障现象：接通电源无任何已通电迹象。故障检修：此故障可能为CPU本身的电源故障。打开机盖发现整流与输出的一体化大功率模块有裂开现象，细查此为人为造成，并无烧焦痕迹，但内部多处连线均已撬断损坏，无法再用。重新换上一块MUBW15-12A7后通电，显示出现EPERR，看来这才是真正的故障，应属于内存问题，更换AT89C56后正常西门子变频器电源维修一例故障现象：西门子变频器电源冷机时要等几钟才启动，热机时可即启动。检查分析：此电源用UC3842控制，能启动说明元器件没坏，但很可能性能下降，经测量UC3842电源端电解电容容量变少，换上新的电解电容反复试机正常。欧陆590直流调速器维修一例故障现象：欧陆590直流调速器不能调速。检查分析：经检查+10V电压基准电源为2V左右，-10V电压基准电源为-7V左右，查看有一IC发热很大，更换后-10V电源正常，但+10V电源为+13V，再测量此IC附近有2个贴片电阻烧断，更换后±10电源正常，接上马达试机调速运行正常。东元伺服控制器维修两例故障现象：东元伺服控制器主控板冷机正常，工作一段时间后元显示，但指示灯亮全亮。检查分析：通常冷机正常而热机不正常说明元器件基本正常，但不些器件性能下降所至，可能是电解电容漏电，令5V电源不稳，经查看此机器的出厂日期超过十年，超过十年的电解电容很易失效，换上所有全新的电解电容后反复试机正常。故障：东元伺服控制器显示“AL-15”报警，起动无输出。分析：查资料“AL-15”为过电流（软件）报警，经检查两个电流互感器均正常，试着屏闭智能模块报警输出端亦无效，触发模块能正常导通截止，后找来另一块主板换上，通电显示不正常，起动输出一个方向不稳，另一方向抖动，再检查模块其中一路输入端对电源正端阻值比其它输入端少很多，对应光耦不正常，经检查，确认光耦有问题，更换光耦后正常。伦茨伺服控制器显示过流故障现象：伦茨伺服控制器显示过流.检查分析：通常引起过流有真过流和假过流，真过流的原因有IG坏而形成三相输出与直流母线短路造成过流。第二种情况是三相输出间相间短路而造成过流。第三种情况是触发电路不正常而造成输出不平衡而造成过电流。假过电流的原因有电流互感器坏造成检测错误，有些电路光电耦合器坏引起检测信号不能传递也会显示过流。经测量IG坏，驱动电路的稳压保护二极管已烧坏，换好的元件带负载试机运行正常。Panasonic-MinasACServoDriverMSD023A1XASEABROWNBOVERI064851-001NSFP064851001PanasonicM***082A1BACServoMotorASEABROWNBOVERIYB560103-CE-26USPPYB560103CE26TexasInstrumentsFieldInterfaceModule505-7202TEXASINSTRUMENTSPLC505-6308USPP5056308AMETEKZF2-480-60-UB-​01USPPZF248060UB01PanasonicKokusaiServoDriveADKB400BPFADHworkingASEABROWNBOVERIACH550-PD-06A9​-4NSFPACH550PD06A94ALLENBRADLEY1756-LSPNSFP1756LSPPANASONICMSD011P1EUSPPMSD011P1EALLENBRADLEY2705-EM11J1396​35USPP2705EM11J13963​5GENERALELECTRICDS3800HRRA1D1AUSPPDS3800HRRA1D1APanasonicACServoDriverMCDDT3520003NewinBoxFreeshipQTY1PanasonicACServoDriverMSDA015A1AFreeShipSICKOPTICELECTRONICODC100-P120USPPODC100P120PanasonicACServoDriverMSDA043A1ANewinBoxFreeShipTEXASINSTRUMENTSPLC505-2555USPP5052555ASEABROWNBOVERIACH550-BD-180A​-4NSFPACH550BD180A4TEXASINSTRUMENTS560-2123560TPROCESS565TCPUASEABROWNBOVERIGNT0137111P000​2USPPGNT0137111P000​2FANUCA16B-0160-0650USPPA16B01600650560-2122TITexasInstrumentsPowerSupply5602122ASEABROWNBOVERIACS60100206000​B1200900USPPACS60100206000​B1PanasonicMUDB045A1R02400WACServoDriveAmplifierPHDINC7980-03-1101NSPP7980031101ASEABROWNBOVERI(ABB)DSDP140BSIEMENS6SC6000-ONA02USPP6SC6000ONA02ASEABROWNBOVERIRVS-6-100/120VNSFPRVS6100120VPanasonicMUMA042A3E400WACServoMotorFreeShipTEXASINSTRUMENTS500-5047-AANALOGOUTPUTMODULE5005047ANIBPanasonic2.0kWACServoMotor***202D1C(freeshipping)ASEABROWNBOVERI57360001-ELUSPP57360001EL(AB01)ACSERVODRIVERPANASONICMSD-11A1XX21WORKINGPERCEPTRON515-0108DIGITALSPOTLIGHTW/MOUNTPanasonicM***022F2GSERVOMOTORNEWASEABROWNBOVERIYYT-102EUSPPYYT102EPanasonicACServoDriverMSDA041A1A100-115V400W(J)TEXASINSTRUMENTSPLCPM550-116USPPPM550116TEXASINSTRUMENTSPLC46198-2USPP461982ITESIEMENSHF463JNSFPHF463JTEXASINSTRUMENTSPLC500-5041NSFP5005041505-CP1434TFTexasInstrumentsSiemensTI505CP1434TFRELIANCEELECTRIC9101-0377USPP91010377TEXASINSTRUMENTSPLC0983801-0003USPP09838010003ACDCREV-804B-2448-​9001USPPREV804B2448900​1ASEABROWNBOVERIACS800-U1-0011​-5USPPACS800U100115TEXASINSTRUMENTSPLC500-6224NSFP5006224PUMPDIVISIONPC3892R16X37​09NSFPPC3892R16X37​09BAILEYCONTROLSINIPT-01USPPINIPT01ASEABROWNBOVERIYT204001-KBUSPPYT204001KBASEABROWNBOVERIYYE109AUSPPYYE109ATexasInstruments500-5029DualCommPort5005029TexasInstruments510-2101WEINIG1LA5131-2FB90-​ZX51USPP1LA51312FB90ZX​51ASEABROWNBOVERIACH401601632+A​0BE0000USPPACH401601632A0​BEASEABROWNBOVERI3HAC-17484-2/0​0NSPP3HAC17484200SIEMENSTEXASINSTRUMENTSMONITORCVU100***ARTEKT-BOXUSPPTBOXTEXASINSTRUMENTSPLC7MT-700NSPP7MT700TEXASINSTRUMENTSPLC500-5010NSFP5005010PERCEPTRON911-0010TEXASINSTRUMENTSPLC500-5016USPP5005016TEXASINSTRUMENTSPLCPFS-3611USPPPFS3611PERCEPTRONUS400D45VPANASONICMADCT1503MINASA3ACSERVODRIVER100WNIBNEWSiemens/TI575-2103CPUModuleVMEPLCTexasInstruments5752103(AB01)ACSERVODRIVEUNITPANASONICADKA100BPTADAWORKINGTEXASINSTRUMENTS110V16POINTINPUTMODULE#500-5001KOLLMORGENSEIDEL60WKS-M240/06-​PBUSPP60WK***24006PBSIEMENS6ES5-391-0AA31USPP6ES53910AA31GEFANUCIC600RB751USPPIC600RB751Returns:NotacceptedTexasInstrumentsRTU-HSA-1SystemCircuitBoardRTUHSA1505-2555TexasInstruments/Si​emensTI5052555R5TexasInstruments520C-1102Series500ControllerASEABROWNBOVERIACH401600632-A​0AE0000USPPACH401600632A0​AEASEABROWNBOVERIFDC86-UNIT1BNSPPFDC86UNIT1B)
