1）232 方式 ，通過一個選件6SE6400-1PC00-0AA0 來連接電腦232端口，*常用，*方便；

     2）通過變頻器端子上的485接口再轉(zhuǎn)接為232，然后與電腦232端口連接；

     3）通過Profibus,這時變頻器和電腦都需要加Profibus選件。

     按照你目前所具備的軟硬件情況，我覺得采用方式2。
 
     這時需注意一點：要選用帶光電隔離的232-485轉(zhuǎn)換器，否則要保證電腦的零電勢與變頻器的零電勢為同一電勢，然后再按照下述步驟操作——

     1）做一根連接筆記本串口和mm440串口的數(shù)據(jù)通訊線（說明書上有引腳接法）；
     2）然后在筆記本上安裝好drivemonitor軟件；
     3）打開drivemonitor軟件，設(shè)置好on line參數(shù)如：COM口及通訊波特率。注意通訊波特率應(yīng)該設(shè)置得和mm440中一致。
