Troubleshooting "FANUC Starting System Software Please Wait" Error
- Controller model (e.g., Series 0i-MF, Series 30i/31i/32i, etc.)
- Firmware/System software version (if shown)
- Exact boot messages and any alarm codes
- Recent events (power outage, software update, hardware change)
It’s a common but frustrating scenario: you power up your Fanuc controller, but instead of the usual interface, you're greeted by the message "Starting System Software, Please Wait"—and it stays there. This "boot loop" or freeze typically indicates that the controller is struggling to load its operating system from memory.
The message "Starting system software. Please wait" is a standard part of the Fanuc controller's boot process, but if it remains on the screen for several minutes without progressing, it indicates a critical system hang. This typically happens when the controller cannot load the core software from its internal memory or finish its initial self-checks. Common Causes for System Hangs
