代码 12650: Channel %1 block %2 axis identifier %3 different in channel %4

问题描述与安全警告

Siemens SINUMERIK 840D CNC 触发了严重的 Channel %1 block %2 axis identifier %3 different in channel %4 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 number %2 = Block number %3 = Source symbol %4 = Channel number with different axis definition Definitions: In cycles that are preprocessed at Power On, onl y those geometry and channel axis identifiers may be used that exist in all channels with the same meani ng. In different channels, different axis indices are assigned to the axis identifier. The axis identifiers are defined via MD 20060 $MC_AXCONF_GEOAX_NAME_TAB and MD20080 $MC_AXCONF_CHANAX_NAME_TAB. Example: C is the 4th channel axis in channel 1 and the 5th channel axis in channel 2. If the axis identifier C is used in a cycle that is preprocessed at Po wer On, then this alarm is issued. Reaction: Interpreter stop NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: Please inform the authorized personnel/service department. 1. Modify machine data: Select the same identifi ers for geometry and channel axes in all channels. Example: The geometry axes are called X, Y, Z in all channels. They can then also be programmed directly in preprocessed channels. 2. Do not program the axis directly in the cycle but define it as a parameter of the axis type. Example: Cycle definition: PROC DRILL(AXIS DRILLAXIS) G1 AX[DRILLAXIS]=10 F1000 M17 Call from the main program: DRILL(Z) Program Continuation: Clear alarm with the RESET key. Restart part program
