Re: NEED HELP ABOUT OKUMA OH-OSP-HMG SYSTEM
The machine tries to recall the last program used when it powers up. If that program has been deleted then it cannot find it and in your case it appears that there was a SUB program being used along with the MIN (main) program.
Superman is correct so PSELECT a new program and the problem will probably go away. If not the make sure there is no “O” in the file name because Okuma considers them a SUB as in CALL O1234. ….your code … RTS.

Experience is what you get just after you needed it.
