Programming
A distinction is made between positioning axes with synchronization at the block end or over
several blocks.
Parameters
POS axes:
Block change occurs at the end of the block when all the path and positioning axes
programmed in this block have reached their programmed end point.
POSA axes:
The movement of these positioning axes can extend over several blocks.
POSP axes:
The movement of these positioning axes for approaching the end position takes place in
sections.
Note
Positioning axes become synchronized axes if they are traversed without the special
POS/POSA identifier.
Continuous-path mode (G64) for path axes is only possible if the positioning axes (POS)
reach their final position before the path axes.
Path axes that are programmed with POS/POSA are removed from the path axis grouping
for the duration of this block.
You will find further information on POS, POSA, and POSP in the section on "Traversing
positioning axes, POS, POSA, POSP".
1.4.8 Synchronized axes
Synchronized axes traverse synchronously to the path from the start position to the
programmed end position.
The feedrate programmed in F applies to all the path axes programmed in the block, but
does not apply to synchronized axes. Synchronized axes take the same time as the path
axes to traverse.
A synchronized axis can be a rotary axis, which is traversed synchronously to the path
interpolation.
