Sinumerik Alarm 20090 Axis %1 travel to fixed stop not possible. Check programming and axis data.
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 MD 37000. 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 movement in the selection block for the axis/spindle for which the “Traverse against fixed stop” function is activated. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Remedy:
Please inform the authorized personnel/service department.
• Check the axis type.
• Check MD 37000.
• Is a machine axis movement missing in the approach block?
Program Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
