伺服電機(jī)一般是用在要求控制精度高的場合(如;速度控制、位置控制、轉(zhuǎn)矩控制)。伺服電機(jī)轉(zhuǎn)子上還有一個(gè)光電編碼器。轉(zhuǎn)子轉(zhuǎn)動帶動光電碼器的碼盤，就是說轉(zhuǎn)子轉(zhuǎn)了多少，編碼器發(fā)出多少個(gè)脈沖到控制器上，所以必須加上伺服控制器，才能控制它的精度，如要加上PLC的話，PLC只是在什么時(shí)候才能起動伺服控制器，什么時(shí)候停止伺服控制器。伺服控制器起動或停止就是啟動停止伺服電機(jī)，伺服控制器比變頻器的控制精度還高。所以我不知道你是用它做什么，PLC說白了，就是開和關(guān)而已，就是所謂的邏輯控制，它只起開關(guān)作用，PLC的I/O口，就是輸入口開和關(guān)來控制輸出口開和關(guān)。如它自帶的有模擬量或加的有模擬量塊的話，它也可以控制模擬量。
