Code TPIF-145: Configuration change time out
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Configuration change time out 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 change to the iPendant window configuration has taken longer than expected. This can occur on startup or after you make a basic system configuration change. It might also occur in the presence of significant system activity. For example this error could occur if sysvars.sv is being backed up via the Network. Remedy: When this error occurs, the display might not be what is expected. In this case, change back to Single mode, and try the operation again.
