Behavior for active frame with mirroring
When determining the lift direction, a check is performed to see whether a frame with mirror
is active. In this case, for the retraction direction, right and left are interchanged referred to
the tangential direction. The direction components in tool direction are not mirrored. This
behavior is activated with using the MD setting:
MD21202 $MC_LIFTFAST_WITH_MIRROR = TRUE
132
Command: Assign input <n> to an interrupt routine. The assigned
interrupt routine starts when input <n> switches.
Parameter: Input number
Type: INT
Range of values: 1 ... 8
Defining the priority
Priority value
Range of values: 1 ... 128
Priority 1 corresponds to the highest priority.
Name of the subprogram (interrupt routine) that is to be executed.
Command: Fast retraction from contour
Command: Programmable traverse direction (in motion block)
Regarding the possibilities of programming with ALF refer to the subject
"Traversing direction for fast retraction from the contour (Page 134) ".
