詳細(xì)介紹
DM3722采用32位DSP處理器為運(yùn)算核心，定位于高技術(shù)水準(zhǔn)通用全隔離型的三相高壓大功率步進(jìn)電機(jī)驅(qū)動(dòng)器。它以比交流伺服更為*的軟件算法結(jié)合強(qiáng)勁的三相功率推動(dòng)單元.的性能表現(xiàn)在，高速大力矩輸出，低噪聲，低振動(dòng)，低發(fā)熱,由于采用內(nèi)置動(dòng)態(tài)微細(xì)分技術(shù)，即使在低細(xì)分的條件下，也能夠達(dá)到高細(xì)分的效果,低中高速運(yùn)行都很平穩(wěn)，噪音超小。驅(qū)動(dòng)器具有電機(jī)參數(shù)學(xué)習(xí)及控制參數(shù)自動(dòng)整定，及運(yùn)行過程微調(diào)自適應(yīng)參數(shù)的變化功能，能夠針對(duì)不同電機(jī)自動(dòng)生成運(yùn)行參數(shù)，大限度發(fā)揮電機(jī)的性能。控制信號(hào)接口：
