【正文】 artition to start, the partition counts n=f/f q. (2) Unknown frequency, then to assigns according to the section. Uses \ Steps and ladders law \ Continuously raises the speed the speed which needs, then locking, according to preplaced curve movement. Fitting the starting frequency, after each section of frequencies hand over the increase (to call steps and ladders frequency) △ f=f/8, namely uses 8 sections of fitting. In the operating control process, (frequency) divides into the outset speed n minute achievement steps and ladders frequency, When steps of machine mutation questions step of machine mutation, certainly must stop in the electrical machinery or fall mutates again to the frequency range in, in order to avoid has a bigger impact to damage the electrical machinery. The mutation signal certainly must last the CP pulse finish after the preceding direction as well as in front of the next direction first CP pulse sends out. steps of machine mutation questions Step of machine mutation, certainly must stop in the electrical machinery or fall mutates again to the frequency range in, in order to avoid has a bigger impact to damage the electrical machinery. The mutation signal certainly must last the CP pulse finish after the preceding direction as well as in front of the next direction first CP pulse sent out in some high 外文資料原文 speed under, the reverse cut essence has contained the mutation three processes speeds and the timer starting value transformation This system speed control is the dependence fixed time produces。 關(guān)鍵詞： MSP430F149，單片機，步進電機，通用控制器 基于 步進電機的控制系統(tǒng)，除了步進電機一般還需要專門的驅(qū)動電源，驅(qū)動 源僅僅 完成功率驅(qū)動部分，用戶并不能使整個控制系統(tǒng)按預(yù)定的、期望的工作狀 態(tài)運行，必須對它的驅(qū)動電源予以控制，用戶需要再次開發(fā)。 步進電機起動及加 /減速控制方案 步進電動機的最高起動頻率（突跳頻率）一般為 到 34KHz，而最高運行頻率則可以達到 N*102 KHz。換向信號一定要在前一個方向的最后一個 CP脈沖結(jié)束后
