Sequence
The machine data MD20194 $MC_IGNORE_NONCSTART_ASUP is set for ASUB channel 1
and activated with NEWCONF. The block N10 is processed. The alarm 65500 appears that
contains the "Display" and "NC Start disable" alarm responses. The part program does not
stop as result. The block N30 is loaded and processed. If the user ASUB is used in the block
middle, it is performed despite pending "NC Start disable" alarm response. The part program
stops at block N122 because of M0. The ASUB can no longer be continued when the NC Start
key is pressed. The "NC Start disable" alarm response is rejected with the alarm 16906. The
previously generated 65500 alarm can be acknowledged only with reset.
