Remedy:
Please inform the authorized personnel/service department. The FC POS-AXIS for linear and rotary axes should be used
or the axis should be declared as an indexing axis. Corresponding machine data for indexing axis declaration:
Modify MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB
Modify MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1
Modify MD10910 $MN_INDEX_AX_POS_TAB_1
Modify MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2
Modify MD10930 $MN_INDEX_AX_POS_TAB_2
Programm
continuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.

[Channel %1: ] Axis %2 cannot be repositioned
Parameters:
%1 = Channel number
%2 = Axis number
Explanation:
The concurrent positioning axis cannot be positioned because it has already been restarted via the VDI interface and is
still active. No repositioning motion takes place and the motion initiated by the VDI interface is not affected.
Reaction:
Alarm display.
Remedy:
None.
Programm
continuation:
Clear alarm with the Delete key or NC START.
20074
[Channel %1: ] Axis %2 wrong index position
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
For a concurrent positioning axis declared as indexing axis, the PLC has given an index number that is not available in
the table.
Reaction:
Alarm display.
Remedy:
Please inform the authorized personnel/service department. Check the indexing axis number given by the PLC and correct
this if necessary. If the indexing axis number is correct and the alarm results from an indexing position table that has been
set too short, check the machine data for indexing axis declaration.
Modify MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB
Modify MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1
Modify MD10910 $MN_INDEX_AX_POS_TAB_1
Modify MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2
Modify MD10930 $MN_INDEX_AX_POS_TAB_2
Programm
continuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
20075
[Channel %1: ] Axis %2 can currently not oscillate
Parameters:
%1 = Channel number
%2 = Axis number
Explanation:
The axis cannot perform an oscillating movement now because it is already being traversed, e.g. in JOG mode.
Reaction:
Alarm display.
Remedy:
End the other traversing motion.
Programm
continuation:
Clear alarm with the Delete key or NC START.
20076
[Channel %1: ] Axis %2 oscillating - mode change not possible
Parameters:
%1 = Channel number
%2 = Axis number
Explanation:
The axis is performing an oscillating movement. Mode change is not possible because oscillation is not allowed in the
selected mode.
