的步長(zhǎng)之后，施加連續(xù)逐漸增加的步長(zhǎng)時(shí)間和電流給電機(jī)，使電機(jī)加速，并可檢測(cè)到一個(gè)過(guò)零點(diǎn)事件。電機(jī)加速過(guò)程中檢測(cè)指定數(shù)量連續(xù)的Z事件之后，開(kāi)始調(diào)整，使得電機(jī)率運(yùn)行，即電機(jī)進(jìn)入自動(dòng)換向模式。如果在加速表取完后，電機(jī)還不能進(jìn)入自動(dòng)換向模式下，電機(jī)將停止。圖7所示為閉環(huán)模式下電機(jī)的啟動(dòng)過(guò)程。

開(kāi)環(huán)模式下的啟動(dòng)過(guò)程也一樣，只是電流或者電壓在電機(jī)進(jìn)入自動(dòng)換向模式之后可以由用戶改變。閉環(huán)模式下，電流或者電壓的限值由用戶強(qiáng)制施加且固定，直到電機(jī)進(jìn)入速度調(diào)整。進(jìn)入速度調(diào)整后，電流不再由用戶控制（ST72141自動(dòng)調(diào)整）。閉環(huán)控制模式下，不論是哪種控制模式（電流或者電壓），速度調(diào)整回路啟動(dòng)。電機(jī)在單片機(jī)的控制下，固定運(yùn)行在速度表決定的速度上。
