《FBM07 好价格*** FBM07》FBM07FBM07:升速时过电流 当负载的惯性较大,而升速时刻又设定得太短时,意味着在升速过程中,变频器的作业效率上升太快,电动机的同步转速敏捷上升,而电动机转子的转速因负载惯性较大而跟不上去,结果是升速电流太大。    3,降速中的过电流 当负载的惯性较大,而降速时刻设定得太短时,也会引起过电流。由于,降速时刻太短,同步转速敏捷下降,而电动机转子因负载的惯性大,仍保持较高的转速,这时相同可所以转子绕组切开磁力线的速度太大而发生过电流。    (2)处理办法    1, 起动时一升速就跳闸,这是过电流非常严峻的现象,首要查看    ① 作业机械有没有卡住    ② 负载侧有没有短路,用兆欧表查看对地有没有短路    ③ 变频器功率模块有没有损坏    ④ 电动机的起动转矩过小,拖动体系转不起来    2, 起动时不立刻跳闸,而在运转过程中跳闸,首要查看    ① 升速时刻设定太短,加长加快时刻    ② 减速时刻设定太短,加长减速时刻    ③ 转矩补偿(U/F比)设定太大,引起低频时空载电流过大    ④ 电子热继电器整定不妥,动作电流设定得太小,引起变频器误动作. 咱们售出的产品都通过专业的测验和认证,且质保一年,15天内包退换,满足后付款。补白:假如对产品的价格,厂家,类型,图片有什么疑问,请直接联络咱们。咱们热忱地期望尽咱们较大的尽力,力求较优惠的产品价格。较短的供货周期以及服务质量,能够为您处理进口备件方面问题。↑价格〓全场2折↓货期〓3亿库存,下单后即可发货↓质量〓全新原装,进口***↑保证〓质保一年↓售后服务〓一年内包退换】 @ ABB机器人备件,DCP10……@ AB:Reliance,SLC500/1747/1746,Micrologix/1761/1763/1762/1766/1764 PLC- 5/1771/1785 ….PLC模块@ Schneider Modicon(施耐德莫迪康)140CPU ……@ GE通用电气,IC697……@ Siemens(西门子):西门子数控,西门子摩尔,6ES5948-3UR23 ……@ TRICONEX―西屋…. 【厦门光沃自动化设备有限公司】【联络人:陈小姐】【免费热线:***】【24小时开机:*** 】 【作业QQ: 2479261344】 Rohde & Schwarz UPSF2 video noise meter, guaranteed Rohde & Schwarz ZZA-S334 Rackmount BW2000 3HU 3/4 CABRohde & Schwarz FSP3-B4 Spectrum Analyzer, 9kHz to 3GHzRohde & Schwarz NRV-Z5 Power sensor 50 Ohm 100 kHz – 6Rohde & Schwarz CMD57-B3-B4-B42-B43-B6-B61-B62-B19 CommROHDE & SCHWARZ CMD-B84 TDMA UPGRADE CARD FOR CMD-80Rohde & Schwarz NRP-Z51-1138.0005.02 Thermal Power SensRohde & Schwarz CMD57-B2-B3-B4-B6-B42-B43-B61-B62-B71-KROHDE & SCHWARZ 2 WAY Coaxial Switch BS-403 482.4615.02Rohde & Schwarz CMU300-B12-B21-B71-K31-K32-K33-K34 CommRohde & Schwarz CMU300 Communications AnalyzerRohde & Schwarz CMD80-B1-B14-B3-B60-B61-B62-B81-B82-B84Rohde & Schwarz CMU300-B12-B21-K31-K32-K33-K34 CommunicRohde & Schwarz DPSP 0-2.7GHz, 0-139dB, 50 Ohm ProgrammRohde & Schwarz NRTZ3 RS232 Interface AdapterRohde & Schwarz 3GHZ FSH3 Handheld Spectrum AnalyzerRohde & Schwarz EMFT-838.6010.52 M-Standard TelevisionRohde & Schwarz NRT-Z43 Directional Power Sensor, 0.04Rohde & Schwarz CMU300-B12-B17-B21/2-B71-B76-U75-K31-K3Rohde & Schwarz CMD80-B1-B14-B60-B61-B62-B82-K1-K2 CommFOXBORO DCS FBM01FOXBORO DCS FBM02FOXBORO DCS FBM03FOXBORO DCS FBM04FOXBORO DCS FBM05FOXBORO DCS FBM06FOXBORO DCS FBM07FOXBORO DCS FBM09FOXBORO DCS FBM10FOXBORO DCS FBM12FOXBORO DCS FBM18FOXBORO DCS FBM201FOXBORO DCS FBM202FOXBORO DCS FBM203FOXBORO DCS FBM204FOXBORO DCS FBM205FOXBORO DCS FBM206/P0916CQFOXBORO DCS FBM207FOXBORO DCS FBM207BFOXBORO DCS FBM207CFOXBORO DCS FBM211FOXBORO DCS FBM214FOXBORO DCS FBM217FOXBORO DCS FBM223FOXBORO DCS FBM224/P0926GGFOXBORO DCS FBM237FOXBORO DCS FBM242FOXBORO DCS FBM41FOXBORO DCS FBM42CP30 FBM44130K-N4-LLPF130M-N4FOXBORO DCS CP30FOXBORO DCS CP40BFOXBORO DCS CP60DNBT P0971WVE69F-TI2-JRSFBI10EFOXBORO FCM100EFOXBORO FCM100EtFOXBORO FCM10EFOXBORO FCM2F2FOXBORO FCP270FPS400-24FOXBORO IPM02FOXBORO IPM2-P0904HAK0143AA-P K0143AC-AP0400BJP0400DLP0400GHP0400HEP0400HHP0400TH-FP0400VEP0400VP-CMP10P0400VTP0400ZGP0500JXP0500RGP0500RUP0500RYP0500SRP0500WXP0700HUP0700WBP0800CEP0800DAP0800DBP0800DCP0800DGP0800DOP0800DVP0901VKP0902BMP0902YUP0903CWP0903MUP0903NQP0903NWP0903ZEP0903ZNP0903ZPP0904BHP0904BSP0904FHP0911QBP0911QB-CP0911QC-CP0911QH-AP0911VJP0912CAP0912CBP0914XAP0914XBP0914YM FCM10EP0914ZMP0916AAP0916ACP0916AEP0916AGP0916AWP0916BXP0916CP FCM10EFP0916DBP0916DCP0916FJP0916FKP0916JPP0916JSP0916JS-0EP0916JWP0916PWP0917HD FOXBORO DCS FBM223P0926CCP0926CP-ZCP270P0926GHP0926JMP0950CAP0960AW CP30P0961EF-CP30BP0960HAP0960JA-CP40P0961BC-CP40BP0961BD-GW30BP0961CAP0961FR-CP60P0961FR-CP60SP0970BC-DNBIP0970BM
