Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Pane does not have focus alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: A popup menu was requested for the pane that does not have focus. This error only occurs in Double, Triple, or Status/Single Display Modes. For instance, if you connect to the iPendant menus from Internet Explorer, bring up a web page that has the ComboBox Control, switch focus to another pane, and then use the mouse to click on the ComboBox Control, you will get this error because the pane does not have focus. Remedy: Press the DISP key to change the focus to the correct pane before requesting the popup menu.
