Rapid lift from contour, LIFTFAST
When the input is switched, LIFTFAST retracts the
tool rapidly from the workpiece contour.
If the SETINT instruction includes an interrupt
routine as well as LIFTFAST, the liftfast is executed
before the interrupt routine.
Example:
N10 SETINT(2) PRIO=1 LIFTFAST
or
N30 SETINT(2) PRIO=1 LIFT_Z LIFTFAST
In both cases, the liftfast is executed when input 2
with top priority is enabled.
•
With N10, execution is stopped with alarm 16010
(as no asynchronized subprogram, ASUP, was
specified).
•
The asynchronized subprogram "LIFT-Z" is
executed with N30.
Sequence of motions with rapid lift
The distance through which the geometry axes are
retracted from the contour on liftfast can be defined
in machine data.
Programmable traversing direction, ALF=...
You enter the direction in which the tool is to travel
on liftfast in the NC program.
The possible traversing directions are stored in
special code numbers on the control and can be
called up using these numbers.
Example:
N10 SETINT(2) PRIO=1 LIFT_Z LIFTFAST
ALF=7
The tool moves – with G41 activated (direction of
machining to the left of the contour) – away from the
contour perpendicularly as seen from above.
ALF = 7
G41
