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.
