10.7 Program sections that can be conditionally interrupted (DELAYFSTON, DELAYFSTOF)
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.
Overlapping/nesting
If two stop delay sections overlap, one from the NC commands and the other from machine
data MD11550 $MN_STOP_MODE_MASK, the largest possible stop delay section will be
generated.
The following features regulate the interaction between NC commands

If a "hard" stop event coincides with the "stop delay section", the entire "stop delay section"
is deselected! Thus, if any other stop occurs in this program section, it will be stopped
immediately. A new program setting (new
stop delay section.
If the Stop key is pressed before the stop delay section and the NCK must travel into the
stop delay section for braking, the NCK will stop in the stop delay section and the stop delay
section will remain deselected!
A stop delay section entered with an override of 0% will not be accepted!
This applies to all "soft" stop events.
STOPALL can be used to decelerate in the stop delay section. A STOPALL, however,
immediately activates all other stop events that were previously delayed.
