連接選項驅動(dòng)器模塊選項模塊與驅動(dòng)器的連接方式因模式而異在其中操作選項模塊。
在適配器模式下操作時(shí)在端口的PowerFlex 750系列驅動(dòng)器控制盒中安裝選項模塊4、5或6。有關(guān)更多安裝詳細信息，請參閱網(wǎng)絡(luò )通信選項卡安裝說(shuō)明，出版物750COM-IN002，隨附選項模塊。
1.斷開(kāi)驅動(dòng)器電源。
2.卸下驅動(dòng)器蓋，提起驅動(dòng)器HIM擋板至打開(kāi)狀態(tài)位置以訪(fǎng)問(wèn)驅動(dòng)控制箱。
3.使用防靜電措施。
4.將以太網(wǎng)電纜的一端連接到網(wǎng)絡(luò )。5.根據網(wǎng)絡(luò )拓撲，執行以下操作之一：
?星形網(wǎng)絡(luò )拓撲路由以太網(wǎng)電纜的另一端從網(wǎng)絡(luò )穿過(guò)驅動(dòng)器底部，然后插入電纜插入選項模塊的ENET1或ENET2網(wǎng)絡(luò )端口。
?線(xiàn)性或DLR網(wǎng)絡(luò )拓撲路由到以太網(wǎng)電纜從網(wǎng)絡(luò )穿過(guò)第一個(gè)驅動(dòng)器的底部，并將其電纜插頭插入選項模塊ENET1網(wǎng)絡(luò )端口。要連接到第二個(gè)驅動(dòng)器，請在第一個(gè)驅動(dòng)器的選項模塊ENET2網(wǎng)絡(luò )端口和第二個(gè)驅動(dòng)器的選項模塊ENET1網(wǎng)絡(luò )端口。
要連接其他驅動(dòng)器，請在中重復這些菊花鏈連接配置和驗證關(guān)鍵驅動(dòng)器參數的方法相同PowerFlex 750系列驅動(dòng)器可以單獨配置用于控制和各種組合的參考函數。
例如，您可以將使其控制的驅動(dòng)器來(lái)自具有來(lái)自網(wǎng)絡(luò )的參考?；蛘吣梢詫Ⅱ寗?dòng)器設置為控制來(lái)自網(wǎng)絡(luò )，引用來(lái)自另一個(gè)外圍或接線(xiàn)板?；蛘吣梢詫Ⅱ寗?dòng)器設置為同時(shí)控制和參考來(lái)自網(wǎng)絡(luò )。
本節中的以下步驟假設驅動(dòng)器將接收邏輯來(lái)自網(wǎng)絡(luò )的命令和引用。
1.驗證驅動(dòng)器參數301-[Access Level]設置為“1”（高級）或“2”（專(zhuān)家）訪(fǎng)問(wèn)此程序中所需的參數。
2.使用驅動(dòng)器參數545-[Speed Ref A Sel]設置驅動(dòng)器速度
參考文獻：
a、 將端口字段設置為“0”，如下所示。將參數字段設置為指向選項所在的端口（插槽）模塊已安裝（對于本例，端口4參考）。
示例對話(huà)框參數字段中的數字“874”上面是驅動(dòng)器中指向端口的參數。
3.驗證驅動(dòng)器參數930-[Speed Ref Source]是否報告驅動(dòng)器引用的源（端口0）是選項所在的端口模塊已安裝（對于本例，端口4參考）。
這確保從網(wǎng)絡(luò )命令的任何參考可以使用驅動(dòng)器參數002-[Commanded SpdRef]進(jìn)行監控。
Connecting the Option Module to the Drive
The option module is connected to the drive differently depending on the mode in which the option module is operated. When Operating in Adapter Mode Install the option module in the PowerFlex 750-Series drive control pod in Port 4, 5 or 6. For more installation details, see the Network Communication Option Card Installation Instructions, publication 750COM-IN002, provided with the option module.1. Remove power from the drive. 2. Remove the drive cover and lift up the drive HIM bezel to its open position to access the drive control pod. 3. Use static control precautions. 4. Connect one end of the Ethernet cable to the network.5. Depending on the network topology, do one of the following: ? Star Network Topology—Route the other end of the Ethernet cable from the network through the bottom of the drive, and insert its cable plug into the option module’s ENET1 or ENET2 network port. ? Linear or DLR Network Topology—Route the other end of the Ethernet cable from the network through the bottom of the first drive, and insert its cable plug into the option module ENET1 network port. To connect to the second drive, attach another Ethernet cable between the first drive’s option module ENET2 network port and the second drive’s option module ENET1 network port. To connect additional drives, repeat these daisy-chain connections in the same way
Configuring and Verifying Key Drive Parameters
The PowerFlex 750-Series drive can be separately configured for the control and Reference functions in various combinations. For example, you could set the drive to have its control come from a peripheral or terminal block with the Reference coming from the network. Or you could set the drive to have its control come from the network with the Reference coming from another peripheral or terminal block. Or you could set the drive to have both its control and Reference come from the network. The following steps in this section assume that the drive will receive the Logic Command and Reference from the network. 1. Verify that drive Parameter 301 - [Access Level] is set to “1” (Advanced) or “2” (Expert) to access the required parameters in this procedure. 2. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed Reference: a. Set the Port field to “0” as shown below
