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.
Reaction: 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 Clear alarm with the Delete key or NC START.
Continuation:
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.
Reaction: Alarm display.
Remedy: Preset axis PLC-controlled (declare single axis).
Program Clear alarm with the Delete key or NC START.
Continuation:
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.
Reaction: 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 Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation: 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Definitions: The sign-of-life cell is no longer being updated by the drive.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)
Reaction: NC not ready.
The NC switches to follow-up mode.
Mode group not ready, also effective for single axes
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Restart drive, check drive software.
