過載(zai)也(ye)是(shi)變(bian)(bian)(bian)頻(pin)(pin)器(qi)跳動比較頻(pin)(pin)繁的(de)故障之(zhi)一(yi)，平時看到過載(zai)現象，首(shou)先(xian)應該分析一(yi)下到底是(shi)電機過載(zai)還是(shi)變(bian)(bian)(bian)頻(pin)(pin)器(qi)自(zi)身過載(zai)。一(yi)般(ban)(ban)來(lai)講電機由(you)于過載(zai)能(neng)(neng)力較強(qiang)，只要(yao)變(bian)(bian)(bian)頻(pin)(pin)器(qi)參數(shu)表(biao)的(de)電機參數(shu)設置得當，一(yi)般(ban)(ban)不大會出現電機過載(zai)。而變(bian)(bian)(bian)頻(pin)(pin)器(qi)本身由(you)于過載(zai)能(neng)(neng)力較差很容(rong)易出現過載(zai)報警。我們可以(yi)檢測(ce)變(bian)(bian)(bian)頻(pin)(pin)器(qi)輸出電壓(ya)。其可能(neng)(neng)原(yuan)因是(shi)加速(su)時間太短，電網電壓(ya)太低(di)、負載(zai)過重(zhong)(zhong)等(deng)原(yuan)因引(yin)(yin)起的(de)。一(yi)般(ban)(ban)可通過延(yan)長加速(su)時間、延(yan)長制動時間、檢查電網電壓(ya)等(deng)；負載(zai)過重(zhong)(zhong)，減小(xiao)負載(zai)；所選的(de)變(bian)(bian)(bian)頻(pin)(pin)器(qi)不能(neng)(neng)拖(tuo)動該負載(zai)，更換、增(zeng)大變(bian)(bian)(bian)頻(pin)(pin)器(qi)容(rong)量；也(ye)可能(neng)(neng)是(shi)由(you)于機械潤(run)滑(hua)不好引(yin)(yin)起，對生產機械進行檢修。外部條件故障也是一種比較常見的故障，西門子G150變頻器顯示報警F30025修理方法 此故障無報警代碼顯示，故障比較隱蔽，不便于查找。如變頻器運行后，用“電位器"外部模擬輸入電壓命令值，調節頻率正常，而用“DC4～20ma" 外部模擬輸入電流命令值，無法調節頻率。其可能原因；一是“dc4～20ma" 外部模擬輸入電流命令信號弱，達不到工作要求；一是“DC4～20ma" 外部模擬輸入電流命令信號“+、-極性"顛倒，接反。
