①操作面板上的按鍵；

②操作接線端子連接的部件（如按鈕和電位器）；

③復合操作（如操作面板設置頻率，操作接線端子連接的按鈕進行啟/停控制）。為了操作方便和充分利用變頻器，也可以采用PLC來控制變頻器。

PLC控制變頻器有三種基本方式：

①以開關量方式控制；

②以模擬量方式控制；

③以RS485通信方式控制。

PLC以開關量方式控制變頻器的硬件連接

變頻器有很多開關量端子，如正轉、反轉和多檔轉速控制端子等，不使用PLC時，只要給這些端子接上開關就能對變頻器進行正轉、反轉和多檔轉速控制。當使用PLC控制變頻器時，若PLC是以開關量方式對變頻進行控制，需要將PLC的開關量輸出端子與變頻器的開關量輸入端子連接起來，為了檢測變頻器某些狀態，同時可以將變頻器的開關量輸出端子與PLC的開關量輸入端子連接起來。

PLC以開關量方式控制變頻器的硬件連接如下圖所示。當PLC內部程序運行使Y001端子內部硬觸點閉合時，相當于變頻器的STF端子外部開關閉合，STF端子輸入為ON，變頻器啟動電動機正轉，調節10、2、5端子所接電位器可以改變端子2的輸入電壓，從而改變變頻器輸出電源的頻率，進而改變電動機的轉速。如果變頻器內部出現異常時，A、C端子之間的內部觸點閉合，相當于PLC的X001端子外部開關閉合，X001端子輸入為ON。
