Code TPIF-141: No memory for connection
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical No memory for connection 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 user has failed to log into the teach pendant menuing system because not enough RAM memory is available to make the connection. The system might still be usable because the connection requires a predefined amount of available memory to start up. Remedy: Add RAM memory to your system. You can also lower the memory limit required for login by changing the system variable $UI_CONFIG.$MEM_LIMIT to a lower value.
