Okuma Alarm P-0826 – Axis Construction Data File Read Error
Alarm P-0826 indicates that the axis construction parameter file (SAXD*.PBU) cannot be found or read from the MDO directory.
This means the CNC control is unable to load the required axis configuration data during startup or initialization.
Common causes include:
-
Missing SAXD*.PBU file in the MDO folder
-
Corrupted axis construction data file
-
Incorrect software installation or update
-
Incomplete data backup restoration
-
Memory or storage failure
The machine cannot correctly initialize axis parameters without this file.
Recommended actions:
-
Verify that the SAXD*.PBU file exists in the MDO directory.
-
Check file integrity and size.
-
Reload axis construction data from backup.
-
Confirm correct software version.
-
Inspect storage device for errors.
If the file is lost and no backup is available, axis parameters must be restored from machine documentation or manufacturer data.
