Open the controller door and look at the 7-segment LED display on the main CPU board. A specific number (e.g., "1" or "0") often indicates where the boot process failed.
If the system still fails to boot, the next step is to interrupt the normal startup process to access the controller's low-level maintenance functions. This is done by entering (sometimes called Initial Program Load or IPL mode).
The "FANUC Starting System Software Please Wait" message indicates that the FANUC CNC machine is initializing its system software. This is a normal part of the startup process, and it's not an error message. fanuc starting system software please wait
To minimize the risk of unbootable control systems, implement the following maintenance routine:
When the system hangs indefinitely on the "Please Wait" screen, the bootloader sequence has been interrupted. The processor is waiting for a response or a file transfer that is not happening. Common Causes of the Boot Hang Open the controller door and look at the
If the system parameters or SRAM contents have become corrupted, the control may hang. Accessing the FANUC Boot System screen can help verify memory integrity. Utilizing the FANUC Boot System Screen
The "Starting System Software Please Wait" message is a standard initialization screen on FANUC CNC controls, such as the Series 0i-D/F and 30i/31i/32i-B. During a normal boot sequence, this screen appears for roughly 30 to 90 seconds while the control loads its basic input/output system (BIOS), initializes hardware components, and mounts the CNC system files from the internal flash memory. This is done by entering (sometimes called Initial
This is not an "alarm" per se. Alarms (ex: SV001, PS0000) appear after the software loads. This message indicates the control cannot finish loading its own operating system.
This guide applies to FANUC CNC controls (Series 0i, 30i/31i/32i, Power Motion i, and RoboDrill).
Remove any PCMCIA cards or USB flash drives inserted into the operator panel. Turn the power back on and observe the screen. Step 2: Access the FANUC Boot System Screen
If the system stays on "Please Wait" indefinitely:
