Stop criteria
A stop event can be triggered by the following
• VDI interface signals from the PLC
• Alarms with NOREADY response
• Stop key
• Read-in disable
• Single BLock
Note
Some NCK events are stopped for a short time, in order to perform a switching operation,
and restart immediately. These include e.g. the ASUB that stops the contour briefly in order
to then start the ASUB program immediately. These events are also allowed in the stop delay
area, however they are pushed back to its end and are thus considered "soft stop events".
Conditions
The following conditions apply while a stop delay area is being processed:
• A change in the feed is ignored while in the stop delay area. A feed disable is thus not effective until the
program area has been exited, and is stopped.
• None of the main run axes, such as command axes and positioning axes, which are traversed with POSA, is
stopped.
• Part program command G4 is permitted in the stop delay area.
Other part program commands that cause a stop in the meantime (e.g. WAITM), are not permitted and trigger
the alarm 16954.
• A stop delay section entered with an override of 0% will not be accepted!
