代码 21610: [Channel %1: ] Axis %2 encoder %3 frequency exceeded
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Axis %2 encoder %3 frequency exceeded 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 = Axis name, spindle number %3 = String (encoder number) Definitions: The maximum permissible frequency of the currently active encoder (axis-spec ific interface signal DB31,... DBX1.5 / 1.6 (position measuring system 1/2)) in the axis-specific MD36300 $MA_ENC_FREQ_LIMIT [n] (n... encoder number, 1 or 2) has been exceeded. The reference of the actual value to the mechanical slide position may have been lost. The alarm can be reprogrammed in MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready). Reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Channel not ready. Remedy: Check MD36300 $MA_ENC_FREQ_LIMIT [n] and NC/PLC interface signal DB31,... DBX1.5 / 1.6 (position measuring system 1/2). Program Continuation: Clear alarm with the RESET key in all channel s of this mode group. Restart part program.
