首先檢查各接線接口是否出現松動,然后檢查串口及中斷號是否有沖突,如果是由于沖突引起的,那么應調整資源,避開沖突。其次,檢查人機界面表面是否出現裂縫,如發(fā)現有裂縫應及時更換。此外,還需要檢查人機界面表面是否有塵垢,若有,用軟布進行清除。觀察檢查控制盒上的指示燈是否工作正常,正常時,指示燈為綠色,并且閃爍。如果上面的部分均正常,可用替換法檢查人機界面,先替換控制盒,再替換觸摸屏,后替換主機。人機界面正常但電腦不能操作。一臺人機界面,經試驗其本身一切正常,但接上主機后,電腦不能操作。處理方法:對于這種情況,原因有二。其一,可能是人機界面驅動程序版本過低,需要安裝的驅動程序。其二,可能是在主機啟動裝載人機界面驅動程序之前。目前,應用較成功的有恒壓供水、各類風機、中央空調和液壓泵的變頻調速。在自動化系統(tǒng)中應用由于變頻器內置有32位或16位的微處理器,具有多種算術邏輯運算和智能控制功能,輸出頻率精度為0.1%~0.01%,且設置有完善的檢測、保護環(huán)節(jié),因此,在自動化系統(tǒng)中獲得廣泛應用。例如:化纖工業(yè)中的卷繞、拉伸、計量、導絲;玻璃工業(yè)中的平板玻璃退火爐、玻璃窯攪拌、拉邊機、制瓶機;電弧爐自動加料、配料系統(tǒng)以及電梯的智能控制等。變提高工藝水平和產品質量方面的應用頻器在數控機床控制、汽車生產線、造紙和電梯上的應用。在提高工藝水平和產品質量方面的應用變頻器還可以廣泛應用于傳送、起重、擠壓和機床等各種機械設備控制領域,它可以提高工藝水平和產品質量。
