Reaction
The reaction to a stop event can be:
● Immediate
Stops immediately even in the stop delay area. Is known as a "hard stop event".
● Delayed
Does not stop (even short-term) until after the stop delay area. Is known as a "soft stop
event".
● Alarm 16954
Program is aborted because illegal program commands have been used in the stop delay
area.
● Alarm 16955
Program is continued, an illegal action has taken place in the stop delay area.
● Alarm 16957
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
area allows the user to reduce the override to 0. The next block in the stop delay area then
begins with override 0 and the described alarm situation occurs.)
Note
MD11411 $MN_ENABLE_ALARM_MASK (activation of warnings) Bit 7 activates this alarm.
