3.2.2.32 G90 Absolute dimensions (reference dimension)
Change−over to the reference dimension system.
G90 AXIS R D
AXES Validity identification of the axes (any value)
R Validity identification for polar radius
D Validity identification for polar angle
In reference dimension programming, the programmed end point of the tool
path always refers to the zero point of the selected coordinate system.
It is possible to change over individual axes or all the axes to reference
dimension programming. If an axis is programmed, only this is changed over
to incremental dimensions; the current dimensioning type remains valid for
the others. If G90 is programmed without DIN addresses, all axes are
changed over into the reference dimension system.
The preparatory function G90 has a modal effect and is only switched off by
the preparatory function G91 (incremental dimension system).
N3 G90 Change over all axes into the reference dimension system.
3.2.2.33 G91 Incremental dimensions (incremental dimension programming)
With the preparatory function G91, the reference dimension system
changes over to the incremental dimension system. Generally, this can be
done for all axes (without address parameters) and also for individual axes.
G91 AXES R D
AXES Validity identification of the axes (any value)
R Validity identification for polar radius
D Validity identification for polar angle
In the incremental dimension system, the end point of the programmed axis
is always programmed relative to its starting point. The sign specifies the
direction of the axis movement; the starting point is the current axis
position.
It is possible to change over individual axes or all the axes to incremental
dimension programming. If an axis is programmed, only this is changed over
to incremental dimension; the current dimensioning type remains valid for
the others. If G91 is programmed without DIN addresses, all axes are
changed over into the incremental dimension system.
The preparatory function G91 has a modal effect and is only switched off by
the preparatory function G90 (reference dimension system).
N7 G91 All axes changed over into the incremental dimension system.
