Code numbers with traversing directions for LFWP
For
LFWP, the direction in the working/machining plane has the following assignment:
●
G17: X/Y plane
ALF=1: Retraction in the X direction
ALF=3: Retraction in the Y direction
●
G18: Z/X plane
ALF=1: Retraction in the Z direction
ALF=3: Retraction in the X direction
●
G19: Y/Z plane
ALF=1: Retraction in the Y direction
ALF=3: Retraction in the Z direction
1.14.8 Motion sequence for interrupt routines
Interrupt routine without LIFTFAST
Axis motion is braked along the path down to standstill (zero speed). The interrupt routine
then starts.
The standstill position is saved as interrupt position and is approached at the end of the
interrupt routine for
REPOS with RMI.
Interrupt routine with LIFTFAST
Axis motion is braked along the path. The LIFTFAST motion is simultaneously executed as
superimposed motion. If the path motion and
LIFTFAST motion have come to a standstill (zero
speed), the interrupt routine is started.
The position on the contour is saved as interrupt position where the
LIFTFAST motion is
started and therefore the path was left.
The interrupt routine with
LIFTFAST and ALF=0 behaves in precisely the same way as the
interrupt routine without
LIFTFAST.
Note
The absolute value through which the geometry axes move when quickly retracting from the
contour can be set using machine data.
