西門子6RA70控制器繼電器不吸修理，故障檢測：控制(zhi)接線端(duan)上以(yi)外(wai)(wai)部給定（電(dian)壓或電(dian)流）信(xin)號(hao)進(jin)行(xing)調(diao)節，最常見的(de)形式(shi)就是(shi)(shi)通過外(wai)(wai)接電(dian)位(wei)器來完成，輸出(chu)頻(pin)率(lv)(lv)(lv)(lv)即(ji)變頻(pin)器實際輸出(chu)的(de)頻(pin)率(lv)(lv)(lv)(lv)，當電(dian)動(dong)(dong)機(ji)所(suo)帶的(de)負載變化時，為使(shi)拖(tuo)(tuo)(tuo)動(dong)(dong)系統(tong)穩定，此(ci)時變頻(pin)器的(de)輸出(chu)頻(pin)率(lv)(lv)(lv)(lv)會根據(ju)系統(tong)情況不斷(duan)地調(diao)整(zheng)(zheng)，因此(ci)輸出(chu)頻(pin)率(lv)(lv)(lv)(lv)是(shi)(shi)在給定頻(pin)率(lv)(lv)(lv)(lv)附近(jin)經(jing)常變化的(de)，從另一個角度來說，變頻(pin)器的(de)輸出(chu)頻(pin)率(lv)(lv)(lv)(lv)就是(shi)(shi)整(zheng)(zheng)個拖(tuo)(tuo)(tuo)動(dong)(dong)系統(tong)的(de)運行(xing)頻(pin)率(lv)(lv)(lv)(lv)，上限頻(pin)率(lv)(lv)(lv)(lv)和下(xia)限頻(pin)率(lv)(lv)(lv)(lv)是(shi)(shi)指(zhi)變頻(pin)器輸出(chu)的(de)最高(gao)、最低頻(pin)率(lv)(lv)(lv)(lv)，通常用(yong)fH和fL來表示，根據(ju)拖(tuo)(tuo)(tuo)動(dong)(dong)系統(tong)所(suo)帶的(de)負載不同，有時要對電(dian)動(dong)(dong)機(ji)的(de)最高(gao)、最低轉速給予限制(zhi)，以(yi)保(bao)證拖(tuo)(tuo)(tuo)動(dong)(dong)系統(tong)的(de)安(an)全和產品的(de)質量，另外(wai)(wai)，由操作面板的(de)誤(wu)操作及外(wai)(wai)部指(zhi)令信(xin)號(hao)的(de)誤(wu)動(dong)(dong)作會引(yin)起(qi)頻(pin)率(lv)(lv)(lv)(lv)過高(gao)過低，設置(zhi)上限頻(pin)率(lv)(lv)(lv)(lv)和下(xia)限頻(pin)率(lv)(lv)(lv)(lv)可起(qi)到保(bao)護作用(yong)。
