8.4 Conditionally interruptible program sections (DELAYFSTON,
DELAYFSTOF)
Function
Conditionally interruptible part program sections are called stop delay sections. No stopping
should occur and the feed should not be changed within certain program sections.
Essentially, short program sections - e.g. for machining a thread - should be protected from
almost all stop events. Stops do not take effect until the program section has been
completed.
Syntax
DELAYFSTON
DELAYFSTOF
The commands are programmed separately in a part program line.
Both commands are only permitted in part programs but not in synchronous actions.
Significance
DELAYFSTON
Define a start of a range in which "soft" stops are delayed up to the
end of the stop delay section.
DELAYFSTOF
Define the end of the stop delay section
Note
For machine data MD11550 $MN_STOP_MODE_MASK Bit 0 = 0 (default), a stop delay
section is implicitly defined if
G331/G332 is active and a path motion or G4 is programmed.
Example: Stop events
In the stop delay section, a change in the feedrate and feedrate inhibit are ignored. They
only become effective after the stop delay section.
Stop events are divided into:
"Soft" stop events Response: delayed
"Hard" stop events Response: immediate
