System information

SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)

Example: *G65 P1402 A500 (calls program #1402 and sets parameter #1 to 500,

parameter #16 to 1402, and parameter #7 to 65)

* Parameters not specified are set to -999.

The addresses refer to the parameters as follows.

X 24

Y 25

Z 26

Notes on Calling a Program with G65

Note 1: If the program specified by address P does not exist, an error will occur.

Note 2: The program called is the rounded value of address P. Example: G65 P12.75

(calls program #13)

ote 3: If no P is in the G65 block, the block is treated as a non-movement block.

Note 4: Addresses not specified are set to -999.

Coordinate system rotation (G68) Cancel Rotation (G69)

G68 can be used to rotate a programmed shape about a predefined center point. The plane of

rotation is defined by G17, G18, G19; the center of rotation is defined by IJK and the angle of

rotation by AA. The command format is as follows.

G68 AA+_____ I____ J____ K____

AA+ is CCW

AA- is CW

IJK specify the center of rotation in the plane selected by G17 G18 G19. The center of rotation

defaults to the current coordinate system zero point at the beginning of each program. If the IJK's

are not present in the G68 block, the center of rotation will be the last center specified. The

rotation angle and rotation center are zeroed at the start of each program.
