常用觸摸屏,一般出廠時,廠家對每一個參數都有一個默認值,這些參數叫工廠值。在這些參數值的情況下,用戶能以面板操作方式正常運行的,但以面板操作并不滿足大多數傳動系統的要求。所以,用戶在正確使用觸摸屏之前,要對觸摸屏參數時從以下幾個方面進行:
(1)確認電機參數,觸摸屏在參數中設定電機的功率、電流、電壓、轉速、*大頻率,這些參數可以從電機銘牌中直接得到。
(2)觸摸屏采取的控制方式,即速度控制、轉距控制、PID控制或其他方式。采取控制方式后,一般要根據控制精度,需要進行靜態或動態辨識。
(3)設定觸摸屏的啟動方式,一般觸摸屏在出廠時設定從面板啟動,用戶可以根據實際情況選擇啟動方式,可以用面板、外部端子、通訊方式等幾種。(4)給定信號的選擇,一般觸摸屏的頻率給定也可以有多種方式,面板給定、外部給定、外部電壓或電流給定、通訊方式給定,當然對于觸摸屏給定也可以是這幾種方式的一種或幾種方式之和。正確設置以上參數之后,觸摸屏基本上能正常工作,如要獲得更好的控制效果則只能根據實際情況修改相關參數。一旦發生了參數設置類故障后,變觸摸屏都不能正常運行,一般可根據說明書進行修改參數。如果以上不行,*好是能夠把所有參數恢復出廠值,然后按上述步驟重新設置,對于每一個公司的變頻器其參數恢復方式也不相同。
二、過壓類故障
觸摸屏(ping)(ping)的過電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)集中(zhong)表現(xian)在(zai)直(zhi)(zhi)(zhi)流(liu)母線(xian)的支流(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)上(shang)。正(zheng)常情況下,觸摸屏(ping)(ping)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)為三相全波整流(liu)后的平均(jun)值。若以380V線(xian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)計算,則平均(jun)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)Ud= 1.35 U線(xian)=513V。在(zai)過電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)發(fa)生(sheng)時(shi)(shi),直(zhi)(zhi)(zhi)流(liu)母線(xian)的儲能電(dian)(dian)(dian)(dian)(dian)容將被(bei)充(chong)電(dian)(dian)(dian)(dian)(dian),當電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)上(shang)至(zhi)760V左右時(shi)(shi),變(bian)頻(pin)(pin)器過電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)保護動作。因此,觸摸屏(ping)(ping)來說,都有一個正(zheng)常的工作電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)范圍,當電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)超(chao)過這(zhe)個范圍時(shi)(shi)很可能損壞變(bian)頻(pin)(pin)器,常見的過電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)有兩(liang)類。
