P5: Oscillation

15.3 Oscillation controlled by synchronized actions

Block search
In Block Search the last valid oscillation function is registered and the machine data
OSCILL_MODE_MASK is activated (default) accordingly, either directly after NC start (when
approaching the start position after block search) or after reaching the start position after block
search.
OSCILL_MODE_MASK Bit 0:
0: Oscillation starts after reaching the start position.
1: Oscillation starts immediately after NC start.
REORG
Reversal point 1 is always approached first before oscillation continues.
ASUB
The oscillation movement continues while an ASUB (asynchronous subprogram) is in progress.
15.3 Oscillation controlled by synchronized actions
General procedure
An asynchronous oscillation movement is coupled via synchronized actions with an infeed
motion and controlled accordingly.
The following description concentrates solely on the motion-synchronous actions associated
with the oscillation function.

Functions
You can implement the following functions with the commands described in the following:
1. Infeed at the reversal point (see Section "Infeed at reversal point 1 or 2 (Page 593)").
2. Infeed at the reversal range (see Section "Infeed in reversal point range (Page 594)").
3. Infeed in both reversal points (see Section "Infeed at both reversal points (Page 595)").
4. Stop the oscillation movement at the reversal point until infeed is terminated (see Section
"Stop oscillation movement at the reversal point (Page 596)").
