9.7 9.7 Conditionally interruptible program sections (DELAYFSTON,
DELAYFSTOF)
Function
Conditionally interruptible parts program sections are called stop delay sections. No stopping
should occur and the feed should not be changed within certain program sections. This
essentially means that short program sections used, for example, to machine a thread,
should be protected from stop events. Stops do not take effect until the program section has
been completed.
Programming
N... DELAYFSTON
N... DELAYFSTOF
The commands are programmed separately in a parts program
line. DELAYFeed STop ON/OF
Both commands are only permitted in parts programs but not in synchronous actions.
Parameters
DELAYFSTON Define the beginning of a section in which "soft" stops are
delayed until the end of the stop delay section is reached.
DELAYFSTOF Define end of a stop delay section.
Note
For machine data MD 11550: STOP_MODE_MASK Bit 0 = 0 (default) a stop delay section is
defined implicitly if G331/G332 is active and a path motion or G4 is programmed. See note
below.
Example of stop events
In a stop delay section, changes in the feedrate or feed disable are ignored. They do not
take effect until after the stop delay section.
Stop events are divided into:
"Soft" stop events
"Hard" stop events
Response: delayed
Response: immediate
