Parameterization by SETINT
An interrupt signal must be assigned to the part programs via NC instruction SETINT. This
turns the part program into an interrupt routine.
The following parameters can be used in the SETINT instruction:
• LIFTFAST: When the interrupt signal arrives, a "Fast retraction of the tool from the
contour" is executed before the interrupt routine starts. The motion direction for the fast
retraction is specified by NC address ALF.
If mirroring is active for execution via frames, machine data
MD21202 $MC_LIFTFAST_WITH_MIRROR can be used to control whether the direction
of retraction is to be mirrored as well during fast retraction.
The displacement for the fast retraction is stored for the 3 geometry axes in
MD21200 $MC_LIFTFAST_DIST (displacement during fast retraction from contour).
If LIFTFAST (fast retraction) is assigned, the maximum axis acceleration for positioning
operations (MD 32300: MAX_AX_ACCEL) is reduced by the factor entered in
MD20610 $MC_ADD_MOVE_ACCEL_RESERVE (acceleration reserve for overlaid
motions).
• BLSYNC: If this parameter is set, the current program block is processed and only then is
the interrupt routine started.
