官方故障排除步骤
Parameters: %1 = Axis name, spindle number Definitions: 1. The "Traverse against fixed stop" function has been programmed with FXS[AX]=1 but the axis does not (yet) support this. Check MD37000 $MA_FIXED_S TOP_MODE. This function is not available for gantry axes and simulated axes. 2. On selection, no movement was programmed for axis AX. AX is a machine axis identifier. 3. It is always necessary to program a traversing mo vement in the selection block for the axis/spindle for which the "Traverse against fi xed stop" function is activated. The alarm can be reprogrammed in the 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: Please inform the authorized personnel/service department. - Check the axis type. - Check MD37000 $MA_FIXED_STOP_MODE. - Is a machine axis movement missing in the approach block? Program Continuation: Clear alarm with the RESET key in all channel s of this mode group. Restart part program.
