Follow-up mode
There is no difference to positioning axes.
End of program
If the axis is not controlled by the PLC, then the program end is not reached until the
oscillation movement is terminated (reaction as for POSA:
Positioning across block boundaries).
If the axis is controlled by the PLC, then it continues to oscillate after program end.
Mode change
The following table shows the operating modes in which oscillation can be implemented.
Changeover to an operating mode which allows oscillation does not affect the oscillation
movement. Changeover to inadmissible operating modes is rejected with an alarm. It is not
possible to traverse an axis in oscillation mode while applying control commands from the
NC program or via operator inputs (JOG) simultaneously; an alarm is output if this is
attempted. The following applies: The type of movement first started has priority.

Single-block processing
If the axis is not controlled by the PLC, then it responds to a single block in the same way as
a positioning axis (POSA), i.e. it continues the movement.
Override
The override is specified by the:
NC/PLC interface
Axial override acts on the oscillation axis.
Programming
The override acts on oscillation axes in the same way as on positioning axes.
