The following functions allow asynchronous oscillation to be activated andcontrolled as a function of NC program execution.NoteIf the setting data is directly written in the part program, then the data change takes effectprematurely with respect to processing of the part program (at the preprocessing time). It ispossible to re-synchronize the part program and the oscillation function commands bymeans of a preprocessing stop (STOPRE).References:Programming Guide1) Activate, deactivate oscillation:● OS[oscillation axis] = 1; Activate oscillation for oscillation axis● OS[oscillation axis] = 0; Deactivate oscillation for oscillation axisNoteEvery axis may be used as an oscillation axis.
