G75 FP=<n> X=0 Y=0 Z=0
FPn references with axis machine date MD30600 $MA_FIX_POINT_POS[n-
1]. If no FP has been programmed, then the first
fixed point will be selected.
G75 Fixed point approach
FP=<n> Fixed point that is to be approached. The fixed point number is specified: <n>
Value range of <n>: 1, 2, 3, 4
MD30610$NUM_FIX_POINT_POS should be set if fixed point number 3 or 4 is to be used.
If no fixed point is specified, fixed point 1 is approached automatically.
X=0 Y=0 Z=0 Machine axes to be traversed to the fixed point.
Here, specify the axes with value "0" with which the fixed point is to be approached
simultaneously.
Each axis is traversed with the maximum axial velocity.
; Approach fixed point 1 in Z
N10 G75 FP=2 X=0 Y=0 ; Approach fixed point 2 in X and Y, e. g. to
The programmed position values for X, Y, Z (any value, here = 0) are ignored, but must still be written.
Reference point approach: G74
Functionality
The reference point can be approached in the NC program with G74. The direction and speed of each axis are stored in
machine data.
G74 requires a separate block and is non-modal. The machine axis identifier must be programmed!
In the block after G74, the previous G command of the "Interpolation type" group (G0, G1,G2, ...) is active again.
The programmed position values for X, Y, Z (any value, here = 0) are ignored, but must still be written.
