IC647MOP001输入模块IC647MOP001输入模块我厂KP8000t热模锻压力机铸造生产线,由5台OMRONC200H型可编程序控制器(PC)控制。下面介绍我们对PC一次CPU停机故障排除方法,以期同行指正。1.故障现象据值班电工反映,系统电源指示灯POWER亮,正常操作外部开关、按按钮时,CPU面板上ERROR报警指示灯亮,外部输出切断,当时刚好上午准备下班。下开机时,从CPU内部冒出一股浓烟,此时,PC交流电压为247V左右。2.故障分析及处理当PC控制出现下列优先级错误时会引起CPU停机:CPUWAIT’G(CPU等待)、MEMORYERR(存储器错误)、NOENDINST(无结束语句)、I/OBUSERR(I/O总线错误)、I/OSETERR(I/O设置错误)、I/OUNITERR(I/O单元错误)、SYSFAILFALS(系统出错)等。用编程器读出出错信息如下:COUWAIT’G、MEMORYERR。拆下该CPU,经查看内部线路,发现CPU内部电源部分一集成件SI-9510A已炸开,显然,CPU不能运行。可能原因是当时电源电压高于OMRON产品给定电压值(240Va.c)7V左右或该集成件本身质量欠佳造成的。更换同型号CPU,ERROR红灯仍亮,系统不能启动,用编程器读出的出错信息依然如故。为了防止意外和查看问题方便,我们将备用的存贮器换上,因其RAM中无用户程序。此时,能引发CPU等待的错误主要有两个方面:特殊I/O单元等待及扩展I/O单元等待。首先,我们查看了扩展单元的各部分,其电源供给正常,发现连接电缆插头松动,插好,试机,PCCPU依然停机,但无存贮器错误显示。由于系统未进行I/O地址登记,为查找原因方便,将扩展机架“离线”操作,直接检查主板特殊单元。存贮器中RAM为空白,只要拆下坏的模板后,CPU就应运行,其RUN指示灯亮(编程器置RUN或MONIT状态)。当拆下主板上OD215模板后,RUN亮,将备用的OD215进行状态设置,替换后也亮。此时,再将原来的存贮器换上,结果编程器上蜂鸣器马上声响,又出现MEMORYERR出错信息,可见存贮器也被烧坏。只能用备用的存贮器,重新输入原始用户程序,分段检查、试车,***后全部重新试车,系统正常,交付使用。直此,笔者认为引起这次停机故障的可能原因是特殊I/O单元OD215损坏,又由于偶然因素如电压偏高,使CPU烧坏及存贮器损坏。3.体会(1)PC控制系统设计时,其电源的稳压设计必须引起重视,以满足当地电压波动范围适合PC规范要求,为此,我们正着手改进原电源线路(2)程序需备份。设计者一般均有程序备份,用户手中也必须有正确的程序清单。(3)平时应当注意何处可以购买到备件,以便及时修复机器。TEXASINSTRUMENTSPLC530-1102USPP5301102ASEABROWNBOVERIMD3B1SPFRGUSPPMD3B1SPFRGTexasInstruments2460221-0001MODICONAS-B984-101USPPASB984101RELIANCEELECTRIC0-51419NSFP051419OMRONNT631C-ST141B-***USPPNT631CST141BEV2TEXASINSTRUMENTS500-5035TEXASINSTRUMENTSPLC555-1105USPP5551105SiemensTI575-2104VMEPLCTEXASINSTRUMENTS500-5005INPUTMODULELOT5005005BAYSIDERS115-100USPPRS115100PanasonicACSERVODRIVERMADDT1207003200Wfreeship(AS01)MSDA043A1APANASONICACSERVODRIVEUSEDWORKINGSQUAREDMA36800USPPMA36800NEWTEXASINSTRUMENTS520C-1102WARNERELECTRICM4430-100000USPPM4430100000PanasonicACServoMDDDT55401.5KWDriverSAJF//PANASONICMDDDT5540L01ACSERVOUSEDTEXASINSTRUMENTSPLC7MT-300NSFP7MT300ASEABROWNBOVERIDSQT-239USPPDSQT239ORMECSACS19E/101BUSPPSACS19E101BASEABROWNBOVERI57310001-GPUSPP57310001GPTEXASINSTRUMENTSPLC500-5013NSPP5005013PanasonicMQDB012AAD02208V100W1.0AACServoDrive0190-15328newTEXASINSTRUMENTSPLC305-12TLM-2USPP30512TLM2PanasonicACServoMotorMHMA102P1G1kWALLENBRADLEY1771-DENSFP1771DEALLENBRADLEY500L-EOA94NSPP500LEOA94ASEABROWNBOVERI05MA21USPP05MA21OnePanasonicMSDA043D1AACServoDriverFreeShipGETTYSM313A-B00-102USPPM313AB00102PANASONICSERVOMOTORMDM202A1GASEABROWNBOVERIMK14A-X020USPPMK14AX020ASEABROWNBOVERI6200DP10800EUSPP6200DP10800ESIEMENS6ES5-946-3UA21USPP6ES59463UA21PanasonicMFA020LE2NSCACServoMotorwith60daywarrantyTEXASINSTRUMENTSPLC505-7510NSFP5057510LAMARCHEA12B-20-48VUSPPA12B2048VTEXASINSTRUMENTSPLC500-5840NSFP5005840TEXASINSTRUMENTSPLC164-2113NSFP1642113PanasonicMCDDT3520053ACServoDriverFreeShipMODICON140-CPU-113-03USPP140CPU11303SIEMENSLMG-90USPPLMG90ASEABROWNBOVERI5735200-AUSPP5735200APanasonicACServoMotorM***021A1AXw/60daywarrantyASEABROWNBOVERIYT212001-ALUSPPYT212001ALALLENBRADLEY1336S-BRF50-AN-EN4-HA2-L5NSFP1336SBRF50ANEN41TexasInstrumentsProgrammerTI101Model100-3101NEWTexasInstruments5TI-3000ROCHESTERINSTRUMENTSYSTEMSCL-9001USPPCL9001ASEABROWNBOVERIDSQC-314AUSPPDSQC314APANASONICACSERVODRIVERADKA100GVTAAACNCASEABROWNBOVERI3GAA092302-ASAG1NSPP3GAA092302ASAG1ASEABROWNBOVERIAPTBK-02USPPAPTBK02BAYSIDERS115-100USPPRS115100DODGEMR94878-L-NZUSPPMR94878LNZFOXBORO130FD-NUSPP130FDNPANASONICACServoMotorM***A082C1BFreeShipASEABROWNBOVERI3HAB-2206-1/1USPP3HAB220611TEXASINSTRUMENTSPLC500-5061USPP5005061OMRONF10-S15RUSPPF10S15RSUNXLTDMS-SF1-BNSFPMSSF1BMITSUBISHIA6BSWPS3USPPA6BSWPS3SIEMENS6ES7-212-1AA01-0XB0FNFP6ES72121AA010XB0PANASONICMSD203A1WACSERVODRIVER(MATSUSHITAELECTRIC),NEWASEABROWNBOVERIACH501-010-4-00P2USPPACH501010400P2BAUMANN54R-25000NSFP54R25000ASEABROWNBOVERIMK14A-ABBUSPPMK14AABBMEASUREX08596900USPP08596900INDRAMATKDS1.1-100-300-W1USPPKDS11100300W1DANFOSS175L3203NSPP175L3203REXROTH0-608-750-103NSFP0608750103)
