Influences On Asynchronous Oscillation - Siemens SINUMERIK Series Function Manual

● During the oscillation movement, axes other than the oscillation axis can be freely
● If the PLC does not have control over the axis, then the axis is treated like a normal
● The oscillation axis can act as the input axis for the transformations (e.g. inclined axis,
● The oscillation axis can act as the master axis for gantry and coupled motion axes.
● It is possible to traverse the axis with jerk limitation (SOFT) and/or with kneeshaped
● In addition to this, the oscillation movement can be activated in synchronism with the
● The oscillation movement can likewise be started, influenced and stopped from the
● Interpolatory oscillation is not possible (e.g. oblique oscillation).

Influences on asynchronous oscillation

Setting data
The setting data required for oscillation can be set with special language commands in the
NCK part program, via the HMI and/or the PLC.
Feedrate
The feed velocity for the oscillation axis is selected or programmed as follows:
● The velocity defined for the axis as a positioning axis is used as the feed velocity. This
● When an oscillation movement is in progress, the feed velocity of the oscillation axis can

interpolated. A continuous infeed can be achieved via a path movement or with a
positioning axis. In this case, however, there is no interpolative connection between the
oscillation and infeed movements.
positioning axis during asynchronous oscillation. In the case of PLC control, the PLC
program must ensure via the appropriate stop bits of the NC/PLC interface that the axis
reacts in the desired way to NC/PLC interface signals. These NC/PLC interface signals
also include end of program, operating mode change and single block.

whether the changed velocity must take effect immediately or whether it should be
activated at the next reversal point.
