【摘要】：對(duì)基于Clipper數(shù)控伺服系統(tǒng)的構(gòu)成和控制方式進(jìn)行闡述,采用速度模式連接,進(jìn)行全閉環(huán)控制。并對(duì)限位和回零進(jìn)行研究,提出軟限位與硬限位結(jié)合的雙重限位方式,回零開關(guān)和索引通道的邏輯組合作為雙觸發(fā)回零條件。在下位機(jī)軟件窗口發(fā)送在線指令、編寫運(yùn)動(dòng)程序或PLC程序進(jìn)行移動(dòng),觀察電機(jī)狀態(tài)位判斷各軸限位和回零功能是否完成,采集回零搜索的實(shí)時(shí)數(shù)據(jù)檢驗(yàn)回零軌跡。系統(tǒng)根據(jù)該限位和回零方式,實(shí)現(xiàn)了超程保護(hù)和精確回零,為高精度位置控制提供了基礎(chǔ)。
[Abstract]:The structure and control mode of CNC servo system based on Clipper are described. The speed mode is used to control the whole closed loop. The double limit mode of soft limit and hard limit is put forward. The logic combination of zero return switch and index channel is used as double trigger zero back condition. The on-line instruction is sent in the software window of the lower computer, the motion program or PLC program is written to move, the motor state position is observed to judge whether the function of limiting and returning zero is completed or not, and the real time data of zero back search is collected to check the trace of return zero. According to the method of limit and return, the system realizes over-range protection and accurate return to zero, which provides the foundation for high precision position control.
