To understand the message, it's first important to know the typical boot process of a FANUC controller. When power is applied, the controller does not simply "turn on." It begins a precisely orchestrated sequence: Data corruption on the FROM/SRAM memory due to
: On many R-30iB controllers, there should be four LEDs; typically, the top two should be lit and the bottom two should be blinking . Any other pattern suggests a hardware fault on the main board or its components. 3. Use the Boot Monitor (BMON) for Recovery
With the power completely off, gently reseat the memory cards (FROM/SRAM modules) and any additional plugin boards. Clean the contacts with electrical contact cleaner if dust or oil mist has infiltrated the cabinet. 3. Dead Backup Battery
Turn off the machine, shut off the main factory breaker for 2 minutes, and power it back on. This fully drains residual power from the capacitors.
On many R-30iB controllers, the top two LEDs should be solid and the bottom two should blink. If they look different, the main board may not be booting correctly. 2. Immediate Software Fixes
