Fanuc Starting System Software Please Wait [better] [FULL · PACK]

Disconnect any memory cards (PCM-CIA or SD cards) from the front slots. Disconnect USB drives from the operator panel. Unplug Ethernet or serial RS-232C communication cables.

and observe if it proceeds past the screen. 2. Boot Monitor Menu (Controlled Start)

This allows the capacitors in the power supply to discharge completely. fanuc starting system software please wait

If no backup exists or the INIT START and restore procedures fail, you may be facing a more severe corruption of the core software. In this case, a full reinstallation of the FANUC system software is required. This process typically requires the official FANUC installation media (e.g., a CF card or CD-ROM) and may need to be performed by a trained FANUC service technician.

If the system loads, try turning it off and back on normally to see if it fixes the issue. If not, you may need a system backup (see step 3). 3. Image Backup Restoration Disconnect any memory cards (PCM-CIA or SD cards)

Fanuc controller "Starting system software, please wait" messages typically indicate an initialization failure stemming from corrupted system files, hardware faults in the SRAM/CPU, or teach pendant communication issues. Troubleshooting involves checking for 7-segment display error codes and performing an "INIT Start" to clear the SRAM, or restoring a previous system image. For further troubleshooting, see the discussion at

If clearing the SRAM does not change the "Please Wait" screen, hardware modules may have poor electrical contact due to machine vibrations. Shut off all electrical power to the machine. and observe if it proceeds past the screen

If this message remains on the screen indefinitely, the boot sequence has stalled. A frozen boot screen indicates that the main central processing unit (CPU) cannot complete its handshake with the graphic control circuit, local memory modules, or peripheral FROM/SRAM modules. Primary Causes of a Frozen Boot Sequence

If the battery voltage drops below 2.7V, the SRAM becomes unstable. On the next power cycle, the control attempts to validate the SRAM checksum. When it fails, the boot process can freeze at the "starting system software" screen because the control is unsure if it has a valid environment to load into.

Disclaimer: Proceed with caution when performing an INIT START, as it will erase your data. Ensure you have backups of your robot programs, especially the AOA (All of Above) backup if possible.

A sudden power drop or brownout during system software writes is a leading cause of corruption. Install a UPS dedicated to the CNC control (not the entire machine’s spindle drives, which draw too much current). The UPS should allow at least 5 minutes of runtime to properly shut down the system via the normal power-off sequence.
