在StartDrive項(xiàng)目里，如果變頻器的參數(shù)設(shè)置已經(jīng)通過USB接口上傳，那么這個(gè)變頻器/或控制單元的序列號(hào)就會(huì)被保存在StertDrive項(xiàng)目里。

對(duì)于已有的StartDrive項(xiàng)目，如何通過USB接口在線變頻器呢？

要使用已有的StartDrive項(xiàng)目在線一臺(tái)同型號(hào)的新變頻器，必須將新變頻器的相關(guān)序列號(hào)添加到項(xiàng)目中，并保存。

設(shè)置過程如下

選擇一個(gè)新設(shè)備

在項(xiàng)目樹里面打開驅(qū)動(dòng)。
雙擊“Online & diagnostics”并打開。
選擇“Online access”。
最近一次是通過USB接口上傳時(shí)，接口設(shè)置會(huì)自動(dòng)保存。在"Online access"下的“Type of the PG/PC interface”中選擇“S7USB”，在“PG/PC interface”中選擇“USB”。
舊變頻器的序列號(hào)會(huì)顯示在設(shè)備地址里（本示例為：XAC503-002064）。
點(diǎn)擊“Select Device”按鈕添加新變頻器的相關(guān)序列號(hào)。
