YH300系列變頻器產(chǎn)品特點：
1.1 YH300系列變頻器是我公司自主開發(fā)生產(chǎn)的高品質(zhì)、多功能、低噪音的矢量控制變頻器。通過對電機(jī)磁通電流和轉(zhuǎn)矩電流的解耦控制，實現(xiàn)了轉(zhuǎn)矩的快速響應(yīng)和控制，能以高控制精度進(jìn)行大范圍的調(diào)速運(yùn)行。
1.2 YH300系列變頻器采用Altera FPGA TI DSP（32位）控制系統(tǒng)，完成真正的電流矢量控制，與V/F控制相比，矢量控制有更大的性。
1.3 增加客戶化設(shè)計，16路數(shù)字量輸入、8路數(shù)字量輸出（可控電流3A）、PG卡差分輸入（增加Z位置信號輸入）,高速脈沖輸入可以達(dá)到4M。
1.4 強(qiáng)大的通訊功能，1路本機(jī)人機(jī)界面、2路標(biāo)準(zhǔn)485通訊、1路CAN總線。其中485、CAN總線通訊接口防高壓設(shè)計，即使象220V錯誤接入系統(tǒng)，也可以保護(hù)。
2、主要技術(shù)參數(shù)：
2.1、輸出頻率范圍：0.00～400.00Hz2.2、速度控制方式：無PG矢量控制（SVC）、有PG矢量控制（VC）、V/F控制2.3、指令通道：操作面板、端子控制、遠(yuǎn)程通訊控制2.4、頻率給定方式：數(shù)字鍵盤給定、模擬量給定（電流、電壓信號）、脈沖頻率給定、遠(yuǎn)程通訊給定、多段速給定、簡易PLC給定、PID閉環(huán)給定等？蓪崿F(xiàn)給定的組合和給定方式的相互切換2.6、速度控制精度：±0.5%速度 （SVC）；±0.1%速度 （VC） 2.7、轉(zhuǎn)矩控制：多種轉(zhuǎn)矩指令設(shè)定方式，可實現(xiàn)真正的張力控制2.8、擺頻控制：多種三角波頻率曲線，滿足紡織行業(yè)的個性化需求2.9、所有的輸入、輸出端子皆為可編程的，方便用戶的使用
3、用途廣泛：
染整機(jī)械、塑料擠出機(jī)、傳送機(jī)械、電梯、印刷機(jī)、玻璃機(jī)械、紡機(jī)-圓盤機(jī)、化纖機(jī)械、造紙機(jī)械、線纜、食品機(jī)械等。

在工業(yè)生產(chǎn)過程中，大量的開關(guān)量順序控制，它按照邏輯條件進(jìn)行順序動作，并按照邏輯關(guān)系進(jìn)行連鎖保護(hù)動作的控制，及大量離散量的數(shù)據(jù)采集。傳統(tǒng)上，這些功能是通過氣動或電氣控制系統(tǒng)來實現(xiàn)的。1968年美國GM（通用汽車）公司提出取代繼電氣控制裝置的要求，第二年，美國數(shù)字公司研制出了基于集成電路和電子技術(shù)的控制裝置，首次采用程序化的手段應(yīng)用于電氣控制，這就是第一代可編程序控制器，稱Programmable Controller（PC）。
個人計算機(jī)（簡稱PC）發(fā)展起來后，為了方便，也為了反映可編程控制器的功能特點，可編程序控制器定名為Programmable Logic Controller（PLC），現(xiàn)在，仍常常將PLC簡稱PC。
PLC的定義有許多種。國際電工委員會（IEC）對PLC的定義是：可編程控制器是一種數(shù)字運(yùn)算操作的電子系統(tǒng)，專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計。它采用可編程序的存貯器，用來在其內(nèi)部存貯執(zhí)行邏輯運(yùn)算、順序控制、定時、計數(shù)和算術(shù)運(yùn)算等操作的指令，并通過數(shù)字的、模擬的輸入和輸出，控制各種類型的機(jī)械或生產(chǎn)過程？删幊绦蚩刂破骷捌溆嘘P(guān)設(shè)備，都應(yīng)按易于與工業(yè)控制系統(tǒng)形成一個整體，易于擴(kuò)充其功能的原則設(shè)計。
上世紀(jì)80年代至90年代中期，是PLC發(fā)展最快的時期，年增長率一直保持為30~40%。在這時期，PLC在處理模擬量能力、數(shù)字運(yùn)算能力、人機(jī)接口能力和網(wǎng)絡(luò)能力得到大幅度提高，PLC逐漸進(jìn)入過程控制領(lǐng)域，在某些應(yīng)用上取代了在過程控制領(lǐng)域處于統(tǒng)治地位的DCS系統(tǒng)。
PLC具有通用性強(qiáng)、使用方便、適應(yīng)面廣、可靠性高、抗干擾能力強(qiáng)、編程簡單等特點。PLC在工業(yè)自動化控制特別是順序控制中的地位，在可預(yù)見的將來，是無法取代的！PANASONIC / AC SERVO DRIVER / MSDA153D1A -WGD
