Locking a program section for "Continue machining at the contour"

Programmed interrupt pointer
If because of manufacturing and/or process-related reasons, "Continue machining at the
contour" may not be possible within a certain program section at a program abort, this program
section can be locked for the target block of a block search.
If after a program abort there is a block search for the interruption point within the locked
program section for "Continue machining at the contour", the last executable block (main run
block) before the start of the locked section is used by the control as target block (hold block).
Programming
Syntax
IPTRLOCK()
Functionality
Marks the beginning of the program section as of which "Continue machining at the contour"
is locked. The next executable block (main run block) in which IPTRLOCK becomes active is
now used as target block for a block search with "Continue machining at the interruption point",
until the release with IPTRUNLOCK. This block is referred to as the hold block in the following.
Effectiveness: Modal
Syntax
IPTRUNLOCK()
Marks the end of the program section locked for "Continue machining at the contour". As of
the next executable block (main run block) in which IPTRLOCK becomes active, the current
block is used again as target block for a block search with "Continue machining at the
interruption point". This block is referred to as the release block in the following.
