Okuma Alarm P-0998 – PLC Sequence Program Load Error

Okuma Alarm P-0998 indicates that the CNC control failed to load the PLC sequence program. This usually happens when the PLC program cannot be read correctly from memory or when there is a problem with the control system during startup. Restarting the machine may clear the alarm, but if the error appears again the PLC program or control electronics may need inspection.
