過(guò)流故障
過(guò)流故障可分為加速、減速、恒速過(guò)電流。其可能是由于變頻器的加減速時(shí)間太短、負(fù)載發(fā)生突變、負(fù)荷分配不均，輸出短路等原因引起的。這時(shí)一般可通過(guò)延長(zhǎng)加減速時(shí)間、減少負(fù)荷的突變、外加能耗制動(dòng)元件、進(jìn)行負(fù)荷分配設(shè)計(jì)、對(duì)線路進(jìn)行檢查。如果斷開(kāi)負(fù)載變頻器還是過(guò)流故障，說(shuō)明變頻器逆變電路已環(huán)，需要更換變頻器。
過(guò)載故障
過(guò)載故障包括變頻過(guò)載和電機(jī)過(guò)載。其可能是加速時(shí)間太短，電網(wǎng)電壓太低、負(fù)載過(guò)重等原因引起的。一般可通過(guò)延長(zhǎng)加速時(shí)間、延長(zhǎng)制動(dòng)時(shí)間、檢查電網(wǎng)電壓等。負(fù)載過(guò)重，所選的電機(jī)和變頻器不能拖動(dòng)該負(fù)載，也可能是由于機(jī)械潤(rùn)滑不好引起。如前者則必須更換大功率的電機(jī)和變頻器；如后者則要對(duì)生產(chǎn)機(jī)械進(jìn)行檢修。
