Several pole traversals
A block can traverse the pole any number of times (e.g. programming of a helix with several
turns). The part program block is subdivided into a corresponding number of sub-blocks.
Analogously, blocks which rotate several times around the pole are likewise divided into sub-
blocks.
Rotary axis as modulo axis
The rotary axis can be a modulo rotary axis. However, this is not a mandatory requirement
as was the case in SW 2 and 3. The relevant restrictions applying in SW 2 and 3 have been
eliminated.
Rotary axis as spindle
If the rotary axis without transformation is used as a spindle, it must be switched to position-
controlled mode with
SPOS before the transformation is selected.
TRANSMIT with supplementary linear axis
With active TRANSMIT, the channel name of posBCS[ax[3]] must have another name in the
part program, like the geometry axes. If posBCS[ax[3]] is written only outside the
TRANSMIT
transformation, this restriction does not apply if the axis has been assigned to a geometry
axis. With active
TRANSMIT, no contour information is processed via ax[3].
REPOS
It is possible to reposition on the sub-blocks produced as a result of the extended TRANSMIT
function in SW 4. In this case, the control uses the first sub-block that is closest to the
repositioning point in the BCS.
Block search
In the case of block search with calculation, the block end point (of the last sub-block) is
approached in cases where intermediate blocks have been generated as the result of the
extended functionality in SW 4.
