Overview of Alarms
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 identi-
fier.
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.
- 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 MD 37000.
• Is a machine axis movement missing in the approach block?
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
20091
Axis %1 has not reached fixed stop
Parameters: %1 = Axis name, spindle number
Definitions: On attempting to traverse against a fixed stop, the programmed end position has been
reached or the traversing movement has been aborted. The alarm can be concealed by
means of the machine data $MA_FIXED_STOP_ALARM_MASK.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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: Correct the part program and the settings:
• Has the traversing block been aborted?
• If the axis position does not correspond to the programmed end position, then correct
the end position.
• If the programmed end position is in the part, the triggering criterion must be checked.
• Has the contour deviation leading to triggering been dimensioned too large? Has the
torque limit been set too high?
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
20092
Axis %1 travel to fixed stop still active
Parameters: %1 = Axis name, spindle number
Definitions: An attempt has been made to move an axis while it is in fixed stop or while the deselec-
tion function has not yet been completed.
