4.3 Continuous-path mode
Impact on synchronization conditions
The programmed blocks between which the rounding contour is added are shortened during
rounding. The original programmed block boundary disappears and is then no longer available
for any synchronization conditions (e.g. auxiliary function output parallel to motion, stop at
block end).
Note
We recommend that when the "Rounding" function is used, synchronization conditions apply
to the end of the block before the rounding location rather than the end of the inserted rounding
block. The following block would then not be started and with a stop at the block end, the
contour of the following block can still be changed.
4.3.3.1

Rounding according to a path criterion (G641)

Function
In continuous-path mode with rounding according to a path criterion, the size of the rounding
area is influenced by the path criteria ADIS and ADISPOS.
The path criteria ADIS and ADISPOS describe the maximum distances which a rounding block
can occupy before and after a block.
Note
Acute angles produce rounding curves with a large degree of curvature and therefore cause
a corresponding reduction in velocity.
Note
ADISPOS is programmed in the same way as ADIS, but must be used specifically for
movements in rapid traverse mode G0.
