大家好，我用伺服電機位置控制模式下，發(fā)出脈沖控制電機運動(dòng)一定位移，私服電機會(huì )出現拖曳滯后的現象，就是運動(dòng)還剩一小段時(shí)電機會(huì )暫停，等個(gè)幾秒鐘再把剩下的運動(dòng)走完。
這樣拖曳滯后會(huì )影響我們系統的實(shí)時(shí)性和精度，這個(gè)怎么處理呢。

從沒(méi)遇到這樣的問(wèn)題，你檢查一下程序。伺服的延遲和加減速時(shí)間，還有速度增益有關(guān)系，雖然是這樣，如果是伺服接受了1000個(gè)脈沖，伺服會(huì )在偏差報警時(shí)間內沒(méi)走夠脈沖的話(huà)會(huì )直接報警，就相當于伺服卡住了。你這個(gè)等個(gè)幾秒才走完剩下脈沖，絕對是和程序有關(guān)系
