产品内容介绍
WOODWARD 8280-412调速扩展器
如果NET A指示灯熄灭：
•将选件模块完全连接并接地至驱动器
将其插入驱动器端口，并将其两个外加螺钉拧紧至建议的扭矩，并使用将选项模块连接到网络以太网电缆。
•将以太网电缆正确连接到以太网连接器。
•使用选项模块旋转开关设置唯一的IP地址，选项模块参数，或BOOTP或DHCP服务器。
如果NET A指示灯呈红色稳定亮起：
•配置选项模块以使用唯一的IP地址并循环电源。
如果NET A指示灯闪烁红色/绿色或红色：
•检查选项模块和扫描仪中的IP地址，并验证控制器可以与选项模块通信。
•Ping选项模块。
•如果选项模块空闲，则为正常状态选项模块未通过DPI与驱动器通信。
驱动器处于固件升级模式。
选项模块存在EEPROM故障。
网络地址开关在通电后已更改。
检测到重复的IP地址故障。
DHCP租约已过期。
网络地址开关设置为“888”
网络配置（IP地址、子网掩码、网关地址）为无效的用户FPGA配置无效。如果遇到意外的通信问题，选项模块诊断项目可能有助于您或罗克韦尔自动化人员进行故障排除这个问题。
可使用PowerFlex查看选项模块诊断项目20-HIM-A6或20-HIM-C6S HIM，DriveExplorer软件，版本6.01或更高版本，或DriveExecutive软件5.01或更高版本。有关查看的详细信息HIM的诊断项目，请参阅PowerFlex 20-HIM-A6/-C6S HIM（人机界面模块）用户手册，出版物20HIM-UM001。选项模块有一个事件队列，用于记录在模块的操作。当此类事件发生时，包含以下内容的条目事件的数字代码和时间戳被放入事件队列。
你可以使用PowerFlex 20-HIM-A6或20-HIM-C6S HIM查看事件队列，DriveExplorer软件，6.01版或更高版本，DriveExecutive软件，版本5.01或更高版本，或其他使用DPI Fault对象的客户端。有关查看的详细信息和用HIM清除事件，请参阅PowerFlex 20-HIM-A6/-C6S HIM（人机界面模块）用户手册，出版物20HIM-UM001。事件队列最多可以包含32个条目，这些条目存储在EEPROM中使事件队列非易失性的芯片。最终，事件队列将变满，因为其内容通过选项模块的电源循环保留并重置。此时，新条目将替换最旧的条目。只有一个事件队列清除操作或包含事件队列将清除事件队列内容。在后一种情况下，选项模块不会生成错误来指示事件队列已损坏。
If NET A indicator is off:
• Securely connect and ground the option module to the drive by fully inserting it into the drive port and tightening its two captive screws to the recommended torque, and connect the option module to the network using an Ethernet cable. • Correctly connect the Ethernet cable to the Ethernet connector. • Set a unique IP address with the option module rotary switches, option module parameters, or a BOOTP or DHCP server. If NET A indicator is steady red: • Configure the option module to use a unique IP address and cycle power. If NET A indicator is flashing red/green or red: • Check the IP address in the option module and scanner, and verify that the controller can communicate with the option module. • Ping the option module. • Normal condition if the option module is idle The option module is not communicating with the drive via DPI. The drive is in firmware upgrade mode. The option module has an EEPROM fault. The network address switches have been changed since powerup. A duplicate IP address fault has been detected. The DHCP lease has expired. The network address switches are set to “888.” The network configuration (IP address, subnet mask, gateway address) is invalid. The User FPGA configuration is invalid.
Viewing Option Module Diagnostic Items
If you encounter unexpected communication problems, the option module’s diagnostic items may help you or Rockwell Automation personnel troubleshoot the problem. Option module diagnostic items can be viewed with the PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, DriveExplorer software, version 6.01 or later, or DriveExecutive software, version 5.01 or later. For details on viewing diagnostic items with the HIM, see the PowerFlex 20-HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication 20HIM-UM001.The option module has an event queue to record significant events that occur in the operation of the module. When such an event occurs, an entry consisting of the event’s numeric code and a timestamp is put into the event queue. You can view the event queue with the PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, DriveExplorer software, version 6.01 or later, DriveExecutive software, version 5.01 or later, or other clients using the DPI Fault object. For details on viewing and clearing events with the HIM, see the PowerFlex 20-HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication 20HIM-UM001. The event queue can contain up to 32 entries, which are stored in an EEPROM chip—making the event queue nonvolatile. Eventually the event queue will become full, since its contents are retained through option module power cycles and resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation or the corruption of the EEPROM group containing the event queue will clear the event queue contents. In the latter case, the option module will not generate a fault to indicate that the event queue was corrupted.
