自動(dòng)級(jí)聯(lián)調(diào)節(jié)是用活套調(diào)節(jié)器的有套量偏差，或微張力控制時(shí)產(chǎn)生的速度修號(hào),對(duì)相應(yīng)的相鄰機(jī)架，或級(jí)聯(lián)方向上含同一根鋼的機(jī)架的速度進(jìn)行修，相關(guān)機(jī)架間的設(shè)定速比不影響其它機(jī)架的速度配合關(guān)系。

由級(jí)聯(lián)速度設(shè)定、自動(dòng)級(jí)聯(lián)調(diào)節(jié)綜合產(chǎn)生的各機(jī)架線速度,再根據(jù)對(duì)應(yīng)機(jī)架的工作輥徑及齒輪減速比等因素，匯總折算為電機(jī)軸轉(zhuǎn)速,然后線性變換為速度給定號(hào), 由主PLC通過(guò)PROFIBUS網(wǎng)傳送給主傳動(dòng)速度調(diào)節(jié)裝置DV-300。速度級(jí)聯(lián)關(guān)系應(yīng)在前后兩根鋼之間斷開(kāi)時(shí),減小前面軋件對(duì)后面軋件的速度干擾。為了減少軋線起動(dòng)對(duì)設(shè)備及電網(wǎng)的沖擊，各直流傳動(dòng)機(jī)架按緩慢斜率逐漸加速到設(shè)定速度。當(dāng)任一機(jī)架起動(dòng)失敗時(shí)系統(tǒng)給出報(bào)警。

3.2`、機(jī)架間速度關(guān)系的手動(dòng)調(diào)整

操作人員可隨時(shí)對(duì)任一相鄰間機(jī)架的速度關(guān)系進(jìn)行手動(dòng)調(diào)整，當(dāng)設(shè)定速度偏差過(guò)大，超過(guò)機(jī)架間自動(dòng)調(diào)節(jié)系統(tǒng)作用范圍或有意識(shí)關(guān)閉自動(dòng)調(diào)節(jié)系統(tǒng)時(shí)，對(duì)速度設(shè)定進(jìn)行人工調(diào)節(jié)。操作時(shí)操作工通過(guò)觀察進(jìn)行調(diào)整，消除機(jī)架間的堆鋼和拉鋼現(xiàn)象。在級(jí)聯(lián)速度設(shè)定系統(tǒng)中用手動(dòng)干預(yù),直接修改機(jī)架的延伸率。手動(dòng)調(diào)整可通過(guò)選擇機(jī)架，用增/減開(kāi)關(guān)來(lái)完成。
