In the Fanuc OT architecture, parameters 900–909 (and sometimes up to 919, depending on the CNC version) are stored in a protected area of the CNC’s non-volatile memory (CMOS). They are not backed up by the standard battery-backed RAM. Instead, they are tied to the CNC’s firmware. Instead, they are tied to the CNC’s firmware
You power on and see ALARM 000 (Emergency Stop). But the real problem is SV0441 (Servo parameter error) or PMC SYSTEM ALARM 20 (PMC RAM parity error). Your battery died, and the 900 parameters are gone. Without the list, you cannot tell the control how many axes or what type of spindles exist.
