Loose components caused by machine vibrations can break connections. Power down the machine and lock out the electrical cabinet. fanuc starting system software please wait
Troubleshooting the FANUC "Starting System Software Please Wait" Blank Screen
A frozen CNC controller can halt an entire production line. One of the most common issues operators face is a machine stuck on the boot screen displaying the message: If your screen is stuck on this message
This clears all programs, parameters, offsets, and PMC data unless you have a backup.
If you reach the "Configuration Menu," select . This bypasses some normal startup checks and may allow you to perform backups or diagnostics. Boot Monitor Mode (BMON) This bypasses some normal startup checks and may
The message "System software starting up, please wait" on a Fanuc CNC or robot controller indicates the system is hanging during its boot sequence. This screen typically appears as the controller attempts to load critical system files from non-volatile memory (FROM) into the working memory (SRAM). Common Causes for Startup Hangs Corrupted SRAM Data:
Before removing hardware, perform a clean power reset. Turn off the machine's main breaker. Wait at least two minutes to allow all capacitors in the power supply and servo amplifiers to discharge fully. Turn the power back on to see if the system clears the glitch. 2. Inspect Control LEDs
If the simple power cycle fails, the next step is to access the boot monitor to initiate a "controlled start," which bypasses some of the normal startup routines.
