Code 4400: MD alteration will cause reorganiza tion of buffered memory (Art %1), (loss of data!) - %2

Parameters: %1 = Memory type %2 = MD identifier, if required Definitions: A machine data has been altered that configures the buffered memory. If the NCK powers up with the altered data, this will lead to reorganization of the buffered memory and thus to the loss of all buffered user data (part programs, tool data, GUD, leadscrew erro r compensation,...) Meaning of the 1st parameter 0x00 buffered memory (internal) 0x01 buffered memory Reaction: Alarm display. Remedy: If the control includes user data that have not yet been saved, then a data backup must be performed before the next NC 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 Continuation: Alarm display showing cause of alarm disapp ears. No further operator action necessary. Diagnostics Manual (DAsl), 03/2009
