delay area.
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 permits the user to lower the override to 0. The next block
in the stop delay area then begins with an override of 0 and the alarm described above
occurs.) MD11411 $MN_ENABLE_ALARM_MASK Bit 7 activates this alarm.
