问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Action %2<A LNX> not possible due to ASUP 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 = Channel ID %2 = Action number/action name Definitions: The action in the 2nd parameter was rejected, sinc e an asynchronous subprogram is currently active. Currently, only the integrated search run is rejected wi th this alarm. The integrated search run is activated, if search run is triggered in the Stop program state. In other words: Parts of a program have already been executed and a following program part is "skipped" with search run in order to continue the program afterwards. The event is not possible if the program is stopped within an asynchronous subprogram or if an asynchronous subprogram had been selected before the ev ent. An asynchronous subprogram is selected, when the triggering asynchronous subprogram event arrives, but the asynchronous subprogram cannot be started (e.g. the asynchronous start program is not started because of a read-in disable or because the Stop key is active). In this case, it is irrelevant whether a user ASUP or a system ASUP has been triggered. User ASUPs are activated via FC-9 or via the fast inputs. The following events lead to system ASUPS: - Mode change - Overstore on - Canceling subprogram level - Switching on of single block, type 2 - Setting machine data effective - Setting user data effective - Change skip levels - Dry run on/off - Program test off - Correction block alarms - Editing modi in Teach - External zero offset - Axis exchange - Delete distance-to-go - Measuring Reaction: Alarm display. Remedy: Repeat the action after the end of the asynchronous subprogram. Program Continuation: Clear alarm with the Delete key or NC START.
