Fanuc Starting System Software Please Wait [TRUSTED]
If you have a complete backup of all parameters, PMC ladder, and programs, you can try a full memory clear.
The control reads the system software (FROM/Flash ROM) and loads it into the working memory (SRAM/DRAM).
If the processor detects a hardware fault, a corrupted file, or missing configuration data during this transfer, the loading sequence halts indefinitely. Top 5 Causes of the Boot Loop Freeze 1. Corrupted System Files or SRAM
Once the core hardware is verified, the Starting System software initiates a handshake between the Main CPU and the Servo Controllers . This is a critical moment. fanuc starting system software please wait
Below is an overview of causes and steps to resolve this issue. Common Causes
In rare cases, a short on a remote I/O unit (ex: FANUC I/O Link, Profibus, or DeviceNet) can feed noise back into the backplane bus. During system software initialization, the CNC polls connected devices. If a device does not respond correctly, the boot process waits indefinitely.
If all software recovery steps fail, the root cause is almost certainly a hardware failure. Known hardware culprits for boot stalls include: If you have a complete backup of all
) during power-up. Select "INIT Start" to clear SRAM and reload system files. Recovery Procedures
: The "Please Wait" suggests that the system is busy loading the software and might take a few moments to complete.
The vast majority of "starting system software please wait" issues are preventable. A proactive maintenance schedule is far cheaper and less stressful than emergency repairs. Top 5 Causes of the Boot Loop Freeze 1
Unplug and replug the yellow internal power connectors and fiber optic (FSSB) cables to clean the optical paths and connections. Power on the machine to check if the status changes. Component Replacement and Professional Repair
Release the keys only when the (a black screen with yellow or white text) appears.
Wait at least to allow all capacitors on the boards to discharge completely. Turn the power back on and observe the screen. Step 2: Inspect Visual Diagnostic Indicators
The message appears during steps 3 and 4. During this time, the control is not yet ready to accept commands, move axes, or run programs.
