西門子V90伺服驅(qū)動(dòng)器與電機(jī)及編碼器電纜長(zhǎng)度問(wèn)題 編碼器信號(hào)的可靠性取決于： ，電纜線一定要兩兩雙絞的屏蔽電纜。也就是編碼器信號(hào)電纜； 第二，編碼器信號(hào)不要單端輸入形式，要差分輸入形式； 第三，編碼器反饋的矢量控制系統(tǒng)，必須要做等電位的連接。也就是電機(jī)的導(dǎo)體外殼與電氣柜的導(dǎo)體外殼用一顆10mm平方截面以上的電纜連接； 第四，電機(jī)電纜要四芯電纜，電機(jī)外殼與變頻器的PE端子用一顆電纜直接連接，這顆線不包括等電位的那顆電纜； 第五，電機(jī)電纜（四芯）要有屏蔽層，屏蔽層兩端接在各自方的金屬外殼上。要環(huán)形連接的，不要豬尾巴形式； 第六，編碼器信號(hào)電纜的屏蔽層也要各自環(huán)形連接在各自方的金屬外殼上； 第七，編碼器的彈性聯(lián)軸器，必須要緊固連接，不能有松動(dòng)。 做到上述七條，編碼器信號(hào)不會(huì)有事。
