The ACTDST display shows 10 mm.
The scaling factor does not have any
influence.
Example with Cycle 11 and tilled working plane:
Tilt A by 45°
Scaling factor 0.2
L IX+10
The ACTDST display shows 10 mm.
The scaling factor and the tilt do not have any
influence.
REFDST Distance remaining to the programmed position
in the machine coordinate system; difference
between actual and target positions
Examples with Cycle 11
Scaling factor 0.2
L IX+10
The REFDST display shows 2 mm.
The scaling factor has an effect on the
distance and thus on the display.
Example with Cycle 11 and tilled working plane:
Tilt A by 45°
Scaling factor 0.2
L IX+10
The REFDST display shows 1.4 mm in the X
and Z axes.
The scaling factor and the tilt have an effect
on the distance and thus on the display.
