科比变频器经常出现OH报警维修,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,
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 > 1650 Ω-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 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 E.OL 过载过载超出允许时间,引发此故障。只有当过载计数器复零后,在E.nOL状态下才能复位此故障可能原因如下:-调节器参数失配,有超调-机械故障或负载过大-变频器选型错误-电机接错线-编码器损坏E.nOL 过载故障解除不再过载,过载计数器复零;过载发生后必须保证一段冷却时间,冷却时间内,显示此信息,可对故障进行复位。此时必须给变频器供电。
