Overview of Alarms
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Reset VDI interface signal "PLC controls axis", then activate "axial reset" and repeat pro-
cess.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
26080
Channel %1 retraction position of axis %2 not programmed or invalid
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: No retraction position has been programmed for the axis trigger time or the position
became invalid.
Reactions: - Alarm display.
Remedy: Preset value by means of POLFA(Axis,Type,Pos), with type = 1 (absolut) or type = 2
(incremental); type = 0 specifies the position as invalid.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
26081
Channel %1 axis trigger of axis %2 was activated, but axis is not PLC-controlled
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: The axis trigger for single axis was initiated. However, the axis is not PLC-controlled at
the trigger time (therefore no single axis) or the position became invalid.
Reactions: - Alarm display.
Remedy: Preset axis PLC-controlled (declare single axis).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
26082
Channel %1 ESR for PLC-controlled axis %2 has been triggered
Parameters: %1 = Channel
%2 = Axis, spindle
Definitions: An axial ESR has been triggered for an individual axis (PLC-controlled axis):
The display can be suppressed by machine date MD 11410:
SUPPRESS_ALARM_MASK bit28 = 1.
Reactions: - Alarm display.
Remedy: The individual axis is in axial stop after the ESR movement.
If an axial reset is performed for the individual axis, the alarm will be deleted
and the individual axis can be traversed again.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
The individual axis is in axial stop after the ESR movement.
If an axial reset is performed for the individual axis, the alarm will be deleted
and the individual axis can be traversed again.
26100
Axis %1 drive %2 sign of life missing
Parameters: %1 = Axis name, spindle number
%2 = Drive number
Definitions: The sign-of-life cell is no longer being updated by the drive.
On output of drive number=0, this alarm may inform about a computing timeout on IPO
level (also see alarm 4240)
Reactions: - NC not ready.
