$MN_ASUP_START_MASK
The machine data specifies which stop reasons are to be ignored for an ASUB start. The
ASUB is started or the following stop reasons are ignored:
Bit 0:
Reason for the stop: Stop key, M0 or M01
If the NCK is in the reset state (or JOG mode), an ASUB is immediately started (without this
bit, an ASUB cannot be started in RESET/JOG).
NOTICE
This bit is implicitly set if, in $MN_PROG_EVENT_MASK if there is a deviation from zero in
one channel!
This bit is implicitly set, if bit 1 is set in $MN_SEARCH_RUN_MODE!
Bit 1:
Starting also permitted even if not all of the axes are referenced.
Bit 2:
Starting permitted even if a read-in inhibit is active, i.e. the blocks of the ASUB program are
immediately loaded and executed. This means that the machine data IGNORE_INHIBIT_AS‐
UP becomes ineffective. The NCK behavior corresponds to that of the machine data allocation
IGNORE_INHIBIT_ASUP= FFFFFFFF.
When the bit is not set:
The ASUB is selected internally, but processed only when the read-in disable is canceled.
The assignment of machine data IGNORE_INHIBIT_ASUP is evaluated.
If the following also applies: IGNORE_INHIBIT_ASUP = 0, then although an ASUB is internally
initiated, the blocks of the ASUB program are only loaded when the read-in inhibit is withdrawn.
When the ASUB is triggered, the path is immediately braked (except with the BLSYNC option).
The read-in inhibit is set again in the ASUB program.
Bit 3:
Caution:
The following function can always be activated in single-channel systems.
Multi-channel systems required, in addition, bit 1 in machine data $MN_BAG_MASK. The
function is only effective for ASUBs, that were activated from the interrupted program state
(channel status reset). The function does not work in multi-channel systems without
$MN_BAG_MASK bit 1.
If an ASUB is automatically started from the JOG mode, then the user may stop in the middle
of the ASUB program. The JOG operating mode is continuously displayed to the user.
In this situation, the user can jog as BIT 3 is set. Without bit 3, this is not possible. In this
situation, the mode change is interlocked with Alarm 16927.
The user can continue the ASUB program using the "start" key.
It goes without saying that the user cannot jog as long as the ASUB program is running. The
user may jog again once the ASUB program has ended.
