    Not sure about the parameter, but if you want to lock the spindle from spinning and orient it, it's M19 in the program, or from MDI.

    Did you stop the spindle with an M5 before using the M19?

    Where did you put the M19 in? In the program? In MDI?

    The okuma manual should tell you what functions and M codes etc they have implemented. Fanuc have Many many pre-assigned functions and it is up to the Machine tool builder to use them (or not) how he sees fit.
    For example all M codes and special functions which can be set by a simple switch such as MLK (machine lock) are implemented through the I/O or ladder section and are machine-tool-builder dependant, they cannot usually be set by parameter.
    There is a whole raft of Fanuc manuals that the end-user does not usually get, he usually gets the Operator manual & Maintenance manual if he is lucky, some times he just gets the Machine tool builder version.
    Just to confuse things but are usefull, Fanuc have an OperatOR as well as a OperatION manual, and a ConnecTION & ConnectING manual as well as Servo man. & others which can be usefull for trouble shooting etc.

    M19 won't work if the chuck is open. Close the chuck (with or without any work-piece in it) and try M19 in the MDI again.

    I see your point, but, I googled for a solution for this issue and didn't find one. I solved the problem myself and posted it in this thread for future reference, in case someone else get the same issue.
