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.
- Alarm display.
None.
Clear alarm with the Delete key or NC START.
Channel %1 axis %2 wrong index position
%1 = Channel number
%2 = Axis name, spindle number
For a concurrent positioning axis declared as indexing axis, the PLC has given an index
number that is not available in the table.
- Alarm display.
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 cor-
rect and the alarm results from an indexing position table that has been set too short,
check the machine data for indexing axis declaration.
Modify MD 30500: INDEX_AX_ASSIGN_POS_TAB
Modify MD 10900: INDEX_AX_LENGTH_POS_TAB_1
Modify MD 10910: INDEX_AX_POS_TAB_1
Modify MD 10920: INDEX_AX_LENGTH_POS_TAB_2
Modify MD 10930: INDEX_AX_POS_TAB_2
Alarm display showing cause of alarm disappears. No further operator action necessary.
Channel %1 axis %2 can currently not oscillate
%1 = Channel number
%2 = Axis number
The axis cannot perform an oscillating movement now because it is already being tra-
versed, e.g. in JOG mode.
- Alarm display.
End the other traversing motion.
Clear alarm with the Delete key or NC START.
Channel %1 axis %2 oscillating - mode change not possible
%1 = Channel number
%2 = Axis number
The axis is performing an oscillating movement. Mode change is not possible because
oscillation is not allowed in the selected mode.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Please inform the authorized personnel/service department. Do not initiate mode change.
Cause the PLC to check the axis and make sure in the PLC program that the axis ends
oscillation if such mode changes take place.
Clear alarm with the RESET key. Restart part program
