    Fanuc 16 changing X axis sign in G53 from minus to plus

    Hello, is there a parameter or option for changing value of machine coordinate system direction, from minus to plus so when i end program by writing
    G53 Z0.
    G53 X200. Y0.
    I wouldnt get an error regarding OT alarm?
    Because normaly i would have to end it writing
    G53 Z0.
    G53 X-200. Y0.

    G53 is the machine co-ord system
    ... G53X0Y0Z0 is also the "homed" machine position
    Any values placed in this line are relative to this home position. There is NO relationship to the work co-ord system(G54-59 etc) if G53 is used

    If home is back-left table corner... then any X value must be +ive
    If home is back-right table corner... then any X value must be -ive

    Which corner is your home ?

    That is all correct but on Haas mills there is an option for selecting x axis direction for g53 pos or neg)so i thought there might be on fanuc also
