代码 4400: MD alteration will cause reorganiza tion of buffered memory (Art %1), (loss of data!) - %2
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 MD alteration will cause reorganiza tion of buffered memory (Art %1), (loss of data!) - %2 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
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
