Conditionally interruptible program sections (DELAYFSTON,

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

The commands are programmed separately in a part program line.

Both commands are only permitted in part programs but not in synchronous actions.

Significance

For machine data MD11550 $MN_STOP_MODE_MASK Bit 0 = 0 (default), a stop delay

section is implicitly defined if

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

"Hard" stop events
