KEB科比变频器显示E.oh问题维修

keb科比变频器显示e.oh问题维修，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温度恢复正常，变为低阻。e.ｐｕ功率单元故障一般是功率电路有故障　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。专业科比变频器维修修理f4-lift以下故障现象：1.上电无显示2.e.oc过电流报护3.e.op过电压报护4.e.oh变频器过热5.e.os超速故障，速度不稳定6.e.enc编码器报警7.e.hsd速度偏差过大8.hyb编码器接口不识别9.e.doh电机过热10.e.pu功率电路坏11.e.hybc无抱闸信号输出13.电梯下行正常，上行不能运转，运转一段距离停车14.电梯平层不稳，反复平层。15编码器找不到零位16.上电跳闸故变频器起动跳bbl18.给定使能信号后不动作19.主接触信号无输出20.有时报e.set，有时能开。科比f5变频器上电报e.os故障维修，可修复科比变频器常见故障：无显示、缺相、过流、过压、欠压、过热、过载、接地、参数错误、有显示无输出、模块损坏等；
