In TO unit, %1 H number %2 assigned more than once. H number linked again.
%1 = TO unit
%2 = H number
This error can only occur when MD $MN_MM_EXTERN_CNC_SYSTEM= 1 or 2. The
Power ON effective machine data bit 10890, $MN_EXTERN_TOOLPROG_MODE, bit 3
has been reset. On reconstructing data handling after Power ON, it has been found that
different edges of the same TO unit have the same H number. They had been linked pre-
viously. They are linked again and MD bit $MN_EXTERN_TOOLPROG_MODE, bit 3 is
set again.
- Alarm display.
H numbers must be assigned only once in a TO unit. Then, machine data bit 10890,
$MN_EXTERN_TOOLPROG_MODE, bit 3 can be set = 0 and a restart can be per-
formed.
Clear alarm with the Delete key or NC START.
Communication job not executable %1
%1 = Reference to which resources are no longer available.
The communication job (data exchange between NCK and MMC, e.g.: loading an NC part
program) cannot be executed because there is insufficient memory space. Cause: Too
many communication jobs in parallel.
- Alarm display.
• Reduce the number of communication jobs taking place at the same time or increase
$MN_MM_NUM_MMC_UNITS
• Restart communication job.
Please inform the authorized personnel/service department. No remedial measures are
possible - the operation triggering the alarm message has to be repeated. Clear the alarm
display with Cancel.
Clear alarm with the Delete key or NC START.
Memory reorganized using standard machine data
The memory management was not able to allocate the NC user memory with the values
in the machine data. Because the total memory available is provided as dynamic and
static memory for the NC user (e.g. for macro definitions, user variables, number of tool
offsets, number of directories and files etc.) and therefore its size is not adequate.
- NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Please inform the authorized personnel/service department. Redefine the NC memory
structure!
A specific machine data for NC user memory allocation cannot be given as the cause of
the alarm. Therefore, the MD initiating the alarm must be determined on the basis of the
default values in the machine data by changing the user-specific memory structure step
by step.
Usually, not just one machine data has been chosen too large and therefore it is advisable
to reduce the memory area by a certain proportion in several MDs.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
