问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Maximum number of axes in channel %1 exceeded. Limit %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 = Channel number %2 = Upper limit for the number of axes in the channel Definitions: MD20070 $MC_AXCONF_MACHAX_USED defines which ma chine axes can be used in this channel. This simultaneously defines the nu mber of active axes in the channel. This upper limit has been exceeded. Note: The channel axis gaps may cause certain indices of MD20070 $MC_AXCONF_MACHAX_USED to remain unused and therefore do not count as active channel axes. Example: - CHANDATA(2) - $MC_AXCONF_MACHAX_USED[0] = 7 - $MC_AXCONF_MACHAX_USED[1] = 8 - $MC_AXCONF_MACHAX_USED[2] = 0 - $MC_AXCONF_MACHAX_USED[3] = 3 - $MC_AXCONF_MACHAX_USED[4] = 2 - $MC_AXCONF_MACHAX_USED[5] = 0 - $MC_AXCONF_MACHAX_USED[6] = 1 - $MC_AXCONF_MACHAX_USED[7] = 0 This channel uses the five machine axes 1, 2, 3, 8, 7, i.e. it has 5 active channel axes. Reaction: NC not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Modify MD20070 $MC_AXCONF_MACHAX_USED. Program Continuation: Switch control OFF - ON.
