 7、 變頻器的接地應(yīng)該與PLC控制回路單獨(dú)接地，在不能夠保證單獨(dú)接地的情況下，為了減少變頻器對控制器的干擾，控制回路接地可以浮空，但變頻器一定要保證可靠接地。在控制系統(tǒng)中建議將模擬量信號線的屏蔽線兩端都浮空，同時(shí)由于在機(jī)組上PLC與變頻器共用一個(gè)大地，因此建議在可能的情況下，將PLC單獨(dú)接地或者將PLC與機(jī)組地絕緣開來。

   8、變頻器的接地
   400V級：C種接地（接地電阻10Ω以下）。
   接地線切勿與焊機(jī)及動(dòng)力設(shè)備共用。
   接地線請按照電氣設(shè)備技術(shù)基準(zhǔn)所規(guī)定的導(dǎo)線線徑規(guī)格。
   如35KW的變頻器接地線線徑推薦為22 mm2，87KW的接地線線徑推薦為50 mm2。
   接地線在可能范圍內(nèi)盡量短。由于變頻器產(chǎn)生漏電流，與接地點(diǎn)距離太遠(yuǎn)則接地 端子的電位不安定。
