Definitions: If this machine data is set, the current machine data values are overwritten by the default
values at the next ramp-up. Under certain circumstances, this may cause data loss (even
in the buffered memory).
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. If the control includes user
data that has not yet been saved, then a data backup must be performed before the next
NCK power-up. By manually resetting the altered MD to the value it had before the last
power-up, reorganization of the memory can be avoided.
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
4502 Channel %1 anachronism %2(%3) -> %4
Parameters: %1 = Channel number
%2 = String: MD identifier
%3 = String: MD identifier
%4 = String: MD identifier
Definitions: Previously, in $MC_RESET_MODE_MASK Bit4 and Bit5, the reset behavior of the 6th or
8th G groupe was determined. This setting is now made in
$MC_GCODE_RESET_MODE.
In order to ensure compatible handling of "old" data backups, the "old" values are taken
from $MC_RESET_MODE_MASK and entered in $MC_GCODE_RESET_MODE.
Reactions: - Alarm display.
Remedy: --
Program Con-
tinuation:
Clear alarm with the Delete key or NC START.
4503 In TO unit, %1 H number %2 assigned more than once. H number linked again.
Parameters: %1 = TO unit
%2 = H number
Definitions: 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.
Reactions: - Alarm display.
Remedy: 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.
Program Con-
tinuation:
Clear alarm with the Delete key or NC START.
5000 Communication job not executable %1
Parameters: %1 = Reference to which resources are no longer available.
Definitions: 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.
Reactions: - Alarm display.
Remedy: • Reduce the number of communication jobs taking place at the same time or increase
$MN_MM_NUM_MMC_UNITS
• Restart communication job.
