詳細(xì)介紹
DMA860H產(chǎn)品是東么川公司采用*的DSP控制芯片與*的控制電路結(jié)合一起所構(gòu)成的新一代智能數(shù)字式細(xì)分型步進(jìn)電機(jī)驅(qū)動(dòng)器。基于精密的PID 電流控制算法設(shè)計(jì)，高速大力矩輸出。靜止時(shí)動(dòng)態(tài)電流自動(dòng)減半，使電機(jī)溫升大為降低，大限度發(fā)揮電機(jī)的性能。用戶(hù)可以設(shè)置1~128 細(xì)分。低、 中、高速運(yùn)行都非常平穩(wěn)，幾乎沒(méi)有振動(dòng)和噪音，完*了步進(jìn)電機(jī)低速振動(dòng)和噪音的缺陷。驅(qū)動(dòng)器內(nèi)部集成了參數(shù)自動(dòng)調(diào)整功能 ， 能夠針對(duì)不同參數(shù)電機(jī)自動(dòng)生成的運(yùn)行參數(shù)。控制信號(hào)端口：
