Function

Description
An ASUB can be initiated in various situations, either by the user, the system or event-
controlled. A user alarm with the "NC Start disable" alarm response prevents the ASUB start
in some situations. For a pending alarm response, a user ASUB from reset acknowledges with
the alarm 16906.
With the appropriate setting of a channel-specific machine data it is possible to start and
perform an ASUB although a user alarm with the alarm response "NC Start disable" is active.
The alarm response is overridden for the ASUB start and permits its execution.
Note
NCK alarms with the "NC Start disable" alarm response are not affected by the override. A
user ASUB from reset is still not possible and will be rejected with the alarm 16906.
User alarms that can be overridden
The number range for the user alarms that can be overridden is classified as follows:
Number range
65000 - 65499
65500 - 65999
66000 - 66999
67000 - 67999
68000 - 68999
69000 - 69999
Note
Although it is possible to override the "NC Start disable" alarm response for the following alarm
number ranges, the other responses of the associated alarms ensure for the stop conditions.
The stop conditions cannot be overridden with the function described in this chapter:
● 66000 – 66999
