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.
