Okuma Alarm-P 0820 Machine data file read
At power on, the machine data file (GNCUB*.PBU) cannot be read from memory (sector device MD0A:) correctly.
1 -> The file is not stored in memory, or file name is different.
2 -> The file type is not “PBU2”.
3 -> File DB size is too large.
4 -> File DB side is too small.
Probable Faulty Locations
1) The machine data PBU file is not stored in the floppy disk shipped with the NC.
2) Operation procedure for loading the PBU file from the floppy disk to the NC memory is incorrect.
(A COPY command must not be used.)
3) Memory error
Measures to Take
1) Check the control floppy disk if the machine data file (GNCUB*.PBU) is stored on it.
2) Load the control floppy disk again.
3) Replace the memory.
