工程上遇到一個(gè)樣的項目，線(xiàn)體上裝著(zhù)一個(gè)測距儀用來(lái)檢測物體的距離，物體裝在絲桿上，伺服帶著(zhù)絲桿運動(dòng)。伺服電機頭正常情況是與絲桿分離的，當需要調節時(shí)氣缸推動(dòng)伺服電機與絲桿離合器接觸。每次伺服與絲桿剛接觸時(shí)有間隙而且比較大，并且離合器接觸的位置都不一樣�，F在需要我觸摸屏設定一個(gè)值，伺服調節物體達到我設定的值。想問(wèn)一下這樣我可以使用PID控制設定伺服電機速度，設定值與測距儀反饋值接近時(shí)就絲桿與伺服通過(guò)離合器脫離

你完全可以用變頻器達到這個(gè)功能 用不上伺服
