Note
The programmed position values for X1, Y1, Z1 (any value, here = 0) are ignored, but must
still be written.
From SW 1.4 SP7
From SW 1.4 SP7 it is possible to take into account four fixed points.
Prerequisite is that the axis machine data MD30610 $MA_NUM_FIX_POINT_POS=4 is set.
Programming example
N05 G75 FP=1 X1=0
N10 G75 FP=2 X1=0
N15 G75 FP=3 X1=0
N20 G75 FP=4 X1=0
N30 M30
Note
If three or four fixed points are called in the program, and
MD30610 $MA_NUM_FIX_POINT_POS is set to 0 or two, error message "017800" is issued
by the NCK (Channel 1 Block ... incorrectly coded position programmed).
