The system initializes the basic input/output system.
If you determine that the Flash ROM is corrupted and you do not have a backup of the machine parameters and ladder logic, contact the machine tool builder or a FANUC service technician immediately. Attempting a reload without backups can render the machine unusable until re-engineered. fanuc starting system software please wait
The duration of this "wait" state is a diagnostic goldmine for an experienced technician. Under normal circumstances, depending on the Fanuc series (from the legacy Series 0 to the modern 30i-B or 31i-B), the boot process should take between 30 seconds and two minutes. A normal, predictable wait indicates a healthy system. However, an unexpectedly prolonged wait—or an infinite loop of the message—signals deeper trouble. Common culprits include a corrupted system software file, a failing memory module on the main board, a depleted backup battery that has caused parameter or program loss, or even a hardware failure in the boot device itself. In these pathological cases, the "Please Wait" message transforms from a mundane status into a cry for help, often requiring the restoration of "from SRAM" data or a complete clean installation of the executive software.
