Advantages of the stop delay section
A program section is processed without a drop in velocity.
If the user aborts the program after a stop with RESET, the aborted program block is after
the protected section. This program block is a suitable search target for a subsequent block
search.
The following main run axes are not stopped as long as a stop delay section is in progress:
● Command axes and
● Positioning axes that travel with
Parts program command
commands that cause a temporary stop (e.g.,
Like a path movement,
Example: Feedrate intervention
If the override is reduced to 6% before a stop delay section, the override becomes active in
the stop delay section.
If the override is reduced from 100% to 6% in the stop delay section, the stop delay section
is completed with 100% and beyond that the program continues with 6%.
The feed disable has no effect in the stop delay section; the program does not stop until after
the stop delay section.
