Clear alarm with the Delete key or NC START.
Channel %1 search run with hold block
%1 = Channel ID
Informational alarm.
The search run was not performed on the interruption block, instead, it touches
down shortly before that. This so-called "hold block" is generated by the part
program command IPTRLOCK, or implicitly defined by $MC_AUTO_IPTR_LOCK.
This is to preven you from performing a search run in critical program areast
(e.g. gear hobbing).
The alarm also displays that, instead of searching for the block that actually
was interrupted before, another block is being searched for.
This behavior is desired and the alarm serves only informational purposes.
- Alarm display.
$MN_SUPPRESS_ALARM_MASK $MC_AUTO_IPTR_LOCK and language command
IPTRLOCK
Clear alarm with the Delete key or NC START.
Channel %1 search run in a program section that cannot be searched
%1 = Channel ID
With the language commands IPTRLOCK and IPTRUNLOCK, the part programmer can
identify part program sections that cannot be searched. Every search run in these
program sections will be acknowledged with alarm 16951.
In other words:
When the alarm appears, the user has started a search run (Serupro type)
and the search target lies in an area that cannot be searched!
An area that cannot be searched can also be defined implicitly with the machine data
$MC_AUTO_IPTR_LOCK.
