Fanuc programs can be separated into the following program number groups

Fanuc programs can be separated into the following program number groups:

Program Number Range


O0001 to O7999

Standard program numbers (typically for the main programs)

O8000 to O8999

Macro program number Group 1

Can be locked by a setting

Macro program numbers for special applications

O9000 to O9049

Can be locked by a parameter

(used with G, M, S, and T functions)

O9000 to O9999

Macro program number Group 2

Can be locked by a parameter

Macro Pro gram Pro tec tion

The ma jor ity of stan dard CNC pro grams do not need pro tec tion of any kind When the word

Visibility of the pro gram on the control screen (pro gram di rec tory display)


Ed it ing of the pro gram contents (also in clud ing pro gram de le tion)

Macro pro grams need pro tec tion more than subprograms, and subprograms need more pro tec –

tion than the stan dard pro grams When plan ning a macro pro gram, it is im por tant to un der stand

In or der to se lect any level of pro tec tion, the ac tual set ting of an ap pro pri ate pa ram e ter must be
