Okuma Alarm A-1100 – Parameters Not Set
Alarm A-1100 indicates that the CNC control has lost or rejected the stored machine parameter data.
Due to a backup data error, the system automatically loaded factory default initialization data.
As a result, all machine-specific parameters must be reconfigured.
Common causes include:
-
Corrupted parameter backup
-
Battery failure (SRAM data loss)
-
Power interruption during parameter write
-
Hard disk or storage failure
-
Incomplete data restoration
The machine cannot operate correctly until all required parameters are properly restored.
Recommended actions:
-
Do not operate the machine in automatic mode.
-
Restore parameters from a verified backup file.
-
Check SRAM battery condition.
-
Verify spindle, axis, and PLC settings.
-
Confirm machine configuration before restart.
If no valid backup is available, parameters must be re-entered manually according to machine documentation.
