Parameters: %1 = New value of machine data %2 = Machine data number %3 = Number of bytes requested that exceeded availability %4 = Type of memory Diagnostics Manual (DAsl), 03/2009 Definitions: An attempt was made to enter a new value in the s pecified 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 by tes 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 (thi s 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 negative 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 opti on 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 sy nchronous 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 Continuation: Clear alarm with the Delete key or NC START.
