2.7.12 Control and effect on stop events
Controlling stop events
Stop events can be controlled for a particular program area in a program section. This
program section is designated as a stop-delay section and is activated/deactivated via
language commands:
• Activation: DELAYFSTON
• Deactivate: DELAYFSTOF
References:
/PGA/ Programming Manual Advanced
NCK events that can be stopped on short notice and whose reaction can result in the stop
delay area for a program section are evaluated according to the following criteria:
• Immediate
• Delayed
• Alarm 16954
• Alarm 16955
• Alarm 16957
Basic logic functions: Mode group, channel, program operation, reset response (K1)

Stops immediately even in the stop delay area. Is known as a "hard stop event".
Stop (even a short term stop) takes place after the stop delay area. Is known as a "soft
stop event".
Program is aborted because illegal program commands have been used in the stop delay
area.
Program is resumed because an illegal action has taken place in the stop delay area.
The program area (stop delay area) enclosed by DELAYFSTON and DELAYFSTOF
could not be activated. As a result, every stop will take effect immediately and is not
subject to a delay! This will always occur when the deceleration begins before the stop
delay area but ends within the stop delay area. Likewise, if the stop delay area is entered
with an override of 0, the stop delay area also cannot be activated. (example: a G4 before
the stop delay section allows the user to reduce the override to 0. The next block in stop
delay area then starts with Override 0 and the described alarm situation occurs.)
MD11411 $MN_ENABLE_ALARM_MASK (activation of warnings), Bit 7 activates this
alarm.
