由于觸點(diǎn)接觸不良,容易出現(xiàn)故障, PLC 用軟件代替大量的中間繼電器和時間繼電器,僅剩下與輸入和輸出有關(guān)的少量硬件,接線可減少互繼電器控制系統(tǒng)的1/101/100,因觸點(diǎn)接觸不良造成的故障大為減少。二是 PLC 本身的輸出端口應(yīng)該采用大功率晶體管,以滿足步進(jìn)電機(jī)各相繞組數(shù)十伏脈沖電壓、數(shù)安培脈沖電流的驅(qū)動要求。西門子 PLC 本身帶有高速脈沖計(jì)數(shù)器和高速脈沖發(fā)生器,其發(fā)出的頻率最大為 10KHz,能夠滿足步進(jìn)電動機(jī)的要求。 其次也更加深了對 PLC200 的了解。 畢業(yè)設(shè)計(jì)(論文)報告 題 目 S7200PLC 本體控制步進(jìn)電機(jī)設(shè)計(jì) 無錫科技職業(yè)學(xué)院畢業(yè)論文 S7200 本體控制步進(jìn)電機(jī) 2 摘要 PLC 控制步進(jìn)電機(jī)在許多工業(yè)系統(tǒng)中應(yīng)用廣泛,本文主要闡述了西門子S7200 的 PLC,以及 MAP 庫的應(yīng)用。 關(guān)鍵詞 : PLC 200 步進(jìn)電機(jī) Abstract PLC control of stepping motor has been widely applied in many industrial systems,This article mainly expounds the Siemens PLC, S 7200, and the application of MAP the manipulator as an example,the ontology of S 7200 PLC control principle of stepper motor,Mainly through the use of the MAP library to control the speed and direction of step motor, thus achieve the goal of control of improve the performance of a stepper motor,Make the step motor smooth movement, speed, low noise, high control precision,The second is a deepened understanding of PLC200.
