Overview of Alarms
NCK alarms
Definitions: An attempt was made to enter a new value in the specified memory configuration machine data. It was
not possible to modify the value, as this would have cleared the contents of the user memory. This
was because the memory requested exceeded the available capacity.
The third parameter specifies the number of bytes by which the maximum user memory was
exceeded.
The fourth parameter specifies the type of memory whose limit was exceeded.
- "D" stands for dynamic or non-buffered user memory (this is where, for example, the LUD variables
are stored and the interpolation buffer size is entered). The capacity of this memory type is defined by
the current memory configuration and the value in MD18210 $MN_MM_USER_MEM_DYNAMIC.
- "S" stands for static or buffered user memory (this is where part programs, offset data, R parameters,
tool data, etc. are stored). This memory type is defined by the current memory configuration and the
value in MD18230 $MN_MM_USER_MEM_BUFFERED.
- "iS" stands for internal static or buffered user memory. This memory type is defined by the current
memory configuration (not settable). A few NCK functions use this memory.
Reaction: Alarm display.
Remedy: If the modification was unintentional, ignore the error message and continue. The alarm has no neg-
ative effects. The remedy depends on the access right and the current memory configuration of the
NCK:
- The intended change is not possible -> Try again with a smaller value. Observe the change in the
number of bytes.
- Is it possible to expand the memory? This option depends on the model in use. (Not possible if
parameter 4 equals "iS").
- The NCK user memory may have been set smaller than it could be. With the appropriate access
authorization, the machine data (see above) can be changed.
- If parameter 4 equals "iS" and no synchronous actions are used, then MD18232
$MN_MM_ACTFILESYS_LOG_FILE_MEM[2] = 0 can be set. Otherwise the desired machine data
change cannot be made.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
4080 Incorrect configuration of indexing axis in MD %1
Parameters: %1 = String: MD identifier
Definitions: The assignment of a position table to an indexing axis or the contents of a position table contains an
error, or the length of a position table has been parameterized with 0.
Reaction: 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.
Remedy: Please inform the authorized personnel/service department. 3 MD identifiers are output, depending
on the type of error.
1. MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB: the error is due to multiple assignment of a posi-
tion table MD10910 $MN_INDEX_AX_POS_TAB_1 or MD10930 $MN_INDEX_AX_POS_TAB_2) to
axes with different types (linear/rotary axis).
2. MD10910 $MN_INDEX_AX_POS_TAB_1 or MD10930 $MN_INDEX_AX_POS_TAB_2: the con-
tents of the displayed tables are incorrect.
- The entered positions must be arranged in increasing size.
- A particular position must not be set more than once.
- If the table is assigned to one or several modulo axes, then the contents must be within the 0 to <
360 degree range.
3. MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1 or MD10920
$MN_INDEX_AX_LENGTH_POS_TAB_2: the length of the displayed position table n was specified
with 0.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
2-36
