Swapping the CPU or Main Board if the software continues to hang after an INIT start. Hardware cost and configuration required.
Inspect the motherboard for physical signs of damage, such as bulging capacitors or burn marks. If the CPU board is defective, it will require professional repair or component-level replacement. 3. Dead Memory Backup Battery
Fanuc is a renowned Japanese company that specializes in the development and manufacture of computer numerical control (CNC) systems, robots, and other industrial automation products. The Fanuc Starting System Software is a critical component of Fanuc's CNC systems, responsible for initializing and configuring the system for operation. However, some users have reported encountering an issue where the system displays "Please Wait" during the startup process, preventing the system from initializing properly. This paper aims to investigate the causes of this issue and provide potential solutions. fanuc starting system software please wait
Data corruption on the FROM/SRAM memory due to improper shutdowns or power surges.
If a peripheral card—such as an Ethernet module, I/O Link board, or axis control card—fails to respond during initialization, the master CPU will wait indefinitely for a response. Swapping the CPU or Main Board if the
The message appears during Step 3 . If the control stays stuck here, it means the loading process has entered an infinite loop or has stalled because it cannot read, write, or verify the software files. Core Causes of the Stuck Boot Screen
Before opening a service ticket or diving into complex diagnostics, perform these basic but critical checks. Many "hangs" are caused by simple, overlooked issues. If the CPU board is defective, it will
A drop in voltage from the CNC control unit’s internal power supply can prevent the digital circuits from operating correctly. Similarly, failed capacitors or a degraded CPU module on the main master board can halt software execution mid-boot. 5. Peripheral and I/O Link Interruptions
If you are currently facing this issue, let me know the following details so I can provide specific steps for your machine:
