科比变频器维修常见报警：主回路断电E.OC过流超出设定的峰值电流-加速斜坡时间太短-负载太大-输出回路短路-接地错误-减速斜坡时间太短-电机电缆过长EMCE.OHI变频器内部过热变频器内部过热：只有变频器内部温度下降3℃以上，在E.nOHI状态下，才能复位此故障。E.OHI变频器内部过热故障解除变频器内部过热故障发生后，不再过热：变频器内部温度下降3℃以上。E.OH功率模块过热功率模块过热。只有在E.nOH下才能复位此故障。原因：-风机堵转-通风量不足；-环境温度过高E.dOH电机过热电机PTC过热；只有PTC又变为低阻，在E.ndOH状态下，才能复位故障。-端子T1/T2电阻>1650Ω-电机过载-温度传感器线断了E.nED无故障未发生有定义的故障（不应出此故障）E.ndOH电机过热障解除电机PTC温度***正常，12.F4.C1D-4B14科比变频器变为低阻。E.PU功率单元故障一般是功率电路有故障KEB科比变频器启动报警维修，NO.PU功率单元未准备好功率电路未准备好E.PUIN功率单元功率电路与控制卡的软件版本不一致。此故障不可复位。E.LSF软启动电路故障主回路合闸瞬间，与限流电阻并联的继电器触点未闭合时，出现此故障会立刻自复位。（分别供电时，显示欠压故障，10S后自复位）如故障信息一直存在，可能原因如下：-限流电阻损坏-输入电压有误或太低-进线电缆压降太多-制动电阻接错或损-制动单元损坏KEB科比变频器维修，KEBCOMBIVERTR6:15r6s3E-900A,19r6s3E-900A;KEB科比变频器维修，KEBCOMBIVERTF5BASIC:05F5B3A-090A,07F5B3A-0A0A,09F5B1B-2B0A,10F5B1B-2A0A,12F5B1D-1A0A,13F5B1E160A,14F5B1E-150A,05F5B3A-390A,07F5B3A-390A,09F5B3A-390A,10F5B1B-3A0A,12F5B1B-350A,13F5B1D-390A,14F5B1D-380A,15F5B1E350A,16F5B1E-340A;KEB科比变频器维修，KEBCOMBIVERTF5COMPACT:05F5C1B-2B0A,07F5C1B-2B0A,09F5C1B-2B0A,10F5C1B-2A0A,12F5C1D-1A0A,13F5C1E160A,14F5C1E-150A,15F5C1G-150A,16F5C0H-170A,17F5C0H-160A,18F5C0R-760A,19F5C0R-760A,20F5C0R-760A,21F5C0R-760A,05F5C1B3B0A,07F5C1B-3B0A,09F5C1B-3A0A,10F5C1B-3A0A,12F5C1B-350A,13F5C1D-390A,14F5C1D-380A,15F5C1E-350A,16F5C1E-340A,17F5C1G350A,18F5C1G-340A,19F5C0H-350A,20F5C0H-940A,21F5C0R-950A,22F5C0R-950A,23F5C0R-940A,24F5C0R-940A;00.F5.0C1-001000.F5.060-012.F4.C1D-4B14科比变频器16.F5.M1E-34EA09.F4.C1D-122010.F4.F1D-4B1112.F4.C1D-4B1416.F4.C1G-M44016.F5.A1E-34_A12.F4.C1D-4B1410.F4.F1D-4B1910.F4.F1D-4B1112.F4.C1D-4B1410.F5.B1B-3A0A12.F5.B1D-3A0A09.F5.B1B-3A0A12.F4.C1D-4B14科比变频器)
