有的又叫偏差頻率或頻率偏差設(shè)定。其用途是當(dāng)頻率由外部模擬信號(hào)（電壓或電流）進(jìn)行設(shè)定時(shí)，可用此功能調(diào)整頻率設(shè)定信號(hào)時(shí)輸出頻率的高低，如圖1。有的變頻器當(dāng)頻率設(shè)定信號(hào)為0%時(shí)，偏差值可作用在0～fmax范圍內(nèi)，有的變頻器（如明電舍、三墾）還可對(duì)偏置極性進(jìn)行設(shè)定。如在調(diào)試中當(dāng)頻率設(shè)定信號(hào)為0%時(shí)，變頻器輸出頻率不為0Hz，而為xHz，則此時(shí)將偏置頻率設(shè)定為負(fù)的xHz即可使變頻器輸出頻率為0Hz。八、頻率設(shè)定輸入信號(hào)增益 此功能僅在用外部模擬信號(hào)設(shè)定頻率時(shí)才有效。它是用來彌補(bǔ)外部設(shè)定信號(hào)電壓與變頻器內(nèi)電壓（ 10v）的不一致問題；同時(shí)方便模擬設(shè)定信號(hào)電壓的選擇，設(shè)定時(shí)，當(dāng)模擬輸入信號(hào)為時(shí)（如10v、5v或20mA），求出可輸出f/V圖形的頻率百分?jǐn)?shù)并以此為參數(shù)進(jìn)行設(shè)定即可；如外部設(shè)定信號(hào)為0～5v時(shí)，若變頻器輸出頻率為0～50Hz，則將增益信號(hào)設(shè)定為200%即可。
