ABBBAILEY1746NT81747L552检测办法和判断：断开电源线，检查电源是否是否有缺相或断路情况，如果电源正常则再次上电后则检查检查变频器中间电路直流侧端子P、N是否有电压，如果上述检查正常则判断变频器内部开关电源损坏。3，开机运行无输出(电动机不启动)检测办法和判断：断开输出电机线，再次开机后观察变频器面板显示的输入频率，同时测量交流输出端子。可能原因是变频器启动参数设置或运行端子接线错误、也可能是逆变部分损坏或电动机没有正确链接到变频器。4，运行时“过电压”保护，变频器停止输出检测办法和判断：检查电网电压是否过高，或者是电机负载惯性太大并且加减速时间太短导致的制动问题，请参考第8条。5，运行时“过电流”保护，变频器停止输出检测办法和判断：电机堵转或负载过大。可以检查负载情况或适当调整变频器参数。如无法奏效则说明逆变器部分出现老化或损坏。6，运行时“过热”保护，变频器停止输出检测办法和判断：视各品牌型号的变频器配置不同，可能是环境温度过高超过了变频器允许限额，检查散热风机是否运转或是电动机过热导致保护关闭。7，运行时“接地”保护，变频器停止输出检测办法和判断：参考操作手册，检查变频器及电机是否可靠接地，或者测量电机的绝缘度是否正常。8，制动问题(过电压保护)检测办法和判断：如果电机负载确实过大并需要在短时间内停车，则需购买带有制动单元的变频器并配置相当功率的制动电阻。如果已经配置了制动功能，则可能是制动电阻损坏或制动单元检测失效。9，变频器内部发出腐臭般的异味检测办法和判断：切勿开机，很可能是变频器内部主滤波电容有破损漏液现象。10，如判断出变频器部件损坏，则联系供应商或送交***维修中心处理。HONEYWELLLSA2B*USED*ALKONP-070DS-24/DC*USED*ALLENBRADLEY1771-OGSERIESATTLOUTPUTMODULE*USED*ALLENBRADLEY1492-CB2H250SERIESB*USED*BANNERMQDC-450RAEURO-STYLEQUICKDISCONNECTCABLE*US...TELEMECANIQUELA1LB080BD*USED*CUTLER-HAMMERD15CR22120V*USED*OMRONE2E2-X2Y1-M4PROXIMITYSENSOR(ASPICTURED)*USED...ALFAL***ALLKB53A-6000-11/2-E-316L*USED*LOTOF2AC/PCADAPTERHJC-FRSCLASS2POWERUNIT*USED...LOTOF2MITSUBISHIA1S38BBASEUNIT*USED*LENZEBFK458-08E*USED*ALLENBRADLEY871P-E13GRTSERIESA*USED*LOTOF2SQUARED9080-FB3211R*USED*LOTOF3SQUARED9080-FB1211R*USED*LOTOF2NUMATICS139-136120/60COIL*USED*LOTOF2NUMATICS139-132P120/60COIL*USED*LOTOF2GENUINESTEARNS6-3-45756-09COIL*USED*LOTOF3DECCO11-148230/60COIL*USED*LOTOF2DECCO9-11115/60COIL*USED*LOTOF2DECC139-187P230/60*USED*ALLENBRADLEY872C-D2NP8-E2SER.C*USED*LOTOF2DECCO9-2464M-056COIL*USED*LOTOF2N109C220/240/60COIL*USED*LOTOF2NAMCOEB201-72163220/60COIL*USED*LOTOF4BELLOWSK593-025COIL120/60*USED*VICKERSSV3-16-0-0-115A?PVALVE115V*USED*LOTOF2BOURNS3590S-A63-102L*USED*LOTOF2KLOCKNERMOELLERFAZNC2*USED*KOINOKH-3011SELECTORSWITCH*USED*INTERMATICMODELET715CELECTRONICS7DAYTIMERSWITCH...TELEMECANIQUEXS1M30PA370D*USED*NUMATICS152JJ4000*USED*SONACMODEL11LPROXIMITYSENSOR*USED*WIE***NN12-60368*NEWINABOX*SQUARED9001-B-35CONTROLSTATION*USED*REMKEINDUSTRIES107A0120A1CABLETRERICETEMPERATURECONTROLLER52-1925*NICE*GASTAH103F*USED*LENZE2002*USED*EAGLESIGNALHP510A601*USED*GECIRCUITBOARD44B398262-001/4?4A397857-G01*USED*GECIRCUITBOARD44B398285-001/4?4A397879-G01*USED*ALLENBRADLEY871C-E4B12SERIESB*USED*TRELECTRONICCE100SENCODER*USED*WINTERSP9270-300PSI/KPAGAUGE*NEWINABOX*SPRECHER+SCHUHCA7-9-10*NEWINTHEBOX*POTTER&BRUMFIELDKRPA-14AG-120*NEWINBOX*EDWA***CONTACTOR46E*NEWINBOX*TELEMECANIQUELC1D09480V*USED*LOTOF2MICROSWITCHBZ-2***5551-A2LIMITSWITCH*USED...CUTLERHAMMERE50DN1SER.A1OPERATINGHEAD*USED*GEV-LINED32CIRCUITBREAKER2POLE*USED*MAC45A-SA1-DFBJ-4J?DVALVE*USED*F&TFKG27UF125V*USED*TELEMACANIQUEXS1N18NA340*USED*PHOENIXCONTACTFLKM-D25-SUB/S*USED*GEMULIMITSWITCHTYP.1251240986*NEWOUTOFABOX*AEGDEP210/AS-BDEP-?210*USED*AEGDEP210*USED*WESTINGHOUSEFB3020(CRACK)*USED*PDIPDCA-ADJ*USED*I***9952-0500/T12-A?110*USED*MODUTECT2S-DMA-001-NL*USED*TURN-ACTD-32ACTUATOR*USED*NUMATROLPE4-0001*USED*MERLINGERINC60N-6A*USED*GOYENRCA20T000*USED*BAUMERELECTRICIFR122420*USED****CMGQL50-100PNEUMATICCYLINDER*NEWINABOX*AERO-MOTIVECO.SR902*NEWOUTOFABOX*POTTERELECTRICVSR-F8INCH*NEWINABOX*HONEYWELLDC200E-1-00R-10?0000-0*USED*TURCKBI5-G18-AZ3X-B1?33150MM*USED*JOSLYNCLARK5U4*USED*APOLLOCF8M1500WOG2INCHES*USED*STI44513-0070*USED*DWYER1823-0-1-S*USED*GENERALELECTRICCR120C04002AA*USED*TDKRAX5-10K*USED*FAELS.A.3-32720*USED*LOTOF2DAYTONPLUG-INRELAY5X824*USED*LOTOF2OPTO22DA5I/OMODULE*USED*MACVALVE92B-ACH-000-DU-?DDAP-1DM*USED*CUTLER-HAMMERCONTACTSTARTERKIT3POLESERIESA1CE15...MICROSWITCHLSC1ELIMITSWITCH*USED*KEYENCEEM-005*USED*FENWALL120F*USED*PPOE0-3461-012-010*USED*ELESTAOLS120*USED*ELTROMATCS500-POB-FBBOARD*USED*ELTROMATCX-CS500BOARD*USED*ELTROMATCS-02.2-AUTO-INBOARD(ASPICTURED)*USED*HEIDENHAINLS513LINEARSCALE*USED*THESINGERCOMPANY05088-CU9109550?5*USED*PECOMODULARCONTROLMODELMMC3006-6695*USED*ITWRANSBURG74735*NICE*ADAPTECTRANTORT160SCSI*USED*HALDEXBARNES8498*USED*DAIICHIKEIKITHERMOMETER0-100DEGREESC*USED*EUCHNERTZ1LE024BHA*USED*C1903ABBS283K63A*USED*)
