16950 Channel %1 search run with hold block
Parameters: %1 = Channel ID
Definitions: 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 prevent
you from performing a search run in critical program areas
(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.
Reaction: Alarm display.
Remedy: $MN_SUPPRESS_ALARM_MASK $MC_AUTO_IPTR_LOCK and language command IPTRLOCK
Program Clear alarm with the Delete key or NC START.
Continuation:
16951 Channel %1 search run in a program section that cannot be searched
Parameters: %1 = Channel ID
Definitions: 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.
Note:
The alarm can only be generated when the simulation is
completed during the search run. The alarm cannot
be output immediately at the start of the search run.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: $MN_SUPPRESS_ALARM_MASK $MC_AUTO_IPTR_LOCK and language command IPTRLOCK
Program Clear alarm with the RESET key. Restart part program
Continuation:
16952 Channel %1 start program command not possible due to MDI
Parameters: %1 = Channel ID
Definitions: NCK is currently executing an ASUB in MDI mode. In this constellation,
parts program command "Start" is not allowed for another channel.
Attention: If an asup is started from JOG, the NCK can internally change to MDI,
if the NCK was previously in MDI and not in RESET.
Note: Without this alarm, the MDI buffer of the other channel would always be started.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Start ASUB in AUTO or ->JOG in AUTO
Program Clear alarm with the RESET key. Restart part program
