SEW变频器散热片过热(oh1)故障原因分析及处理
oh1也是一种比较常见的故障，主要原因：检查检查变频器控制端子(13、12、11)之间是否短路；检查温度传感器检测电路是否正常；另外还应检查变频器的冷却风扇运行是否正常；散热片通风情况，散热片是否有堵塞现象；周围环境温度是否过高。
实例：一台SEW变频器 ，上电显示散热片过热(oh1)。
分析与维修：因为是新安装变频器，一送电后就有故障，所以变频器坏的可能性不大；散热片是无堵塞现象；冷却风扇运行正常。断电后，用万用表测试模拟量输入回路，检查变频器控制端子(13、12、11)之间短路，原因是模拟量输入回路中外接频率设定“电位器”电阻值过小所致，更换为wxwxx0.25-1，0.25w 47～4.7k电位器，上电开机后变频器运行良好，运行中没有再发生此故障。
变频器内过热(oh3)故障原因分析及处理
oh3也是一种比较常见的故障，主要原因：负载是否过大； 变频器温度过高故障，如发生温度过高报警，经检查温度传感器正常，则可能是干扰引起的，可以把故障屏蔽。另外还应检查变频器的冷却风扇及散热片通风情况，更换堵转冷却风扇，转动慢风机进行修复，清扫变频器，消除散热片堵塞；周围环境温度是否过高，降低周围环境温度。对于其它类型的故障，*好与厂家联系，获得快速可行的解决方法。
