變頻器對(duì)微機(jī)控制板的干擾 在使用變頻器的控制系統(tǒng)中，多采用微機(jī)或者PLC進(jìn)行控制，在系統(tǒng)設(shè)計(jì)或者改造過程中，一定要注意變頻器對(duì)微機(jī)控制板的干擾問題。由于用戶自己設(shè)計(jì)的微機(jī)控制板一般工藝水平差，不符合EMC國際標(biāo)準(zhǔn)，在采用變頻器后，產(chǎn)生的傳導(dǎo)和輻射干擾，往往導(dǎo)致控制系統(tǒng)工作異常，因此需要采取必要措施。 1良好的接地。電機(jī)等強(qiáng)電控制系統(tǒng)的接地線必須通過接地匯流排可靠接地，微機(jī)控制板的屏蔽地，好單獨(dú)接地。對(duì)于某些干擾嚴(yán)重的場(chǎng)合，建議將傳感器、I/O接口屏蔽層與控制板的控制地相連。 2給微機(jī)控制板輸入電源加裝EMI濾波器、共模電感、高頻磁環(huán)等，成本低。
