Programming feed F
This feed value is effective from point P
3
(or from point P
2
, if
FAD
is not programmed). If no F command is
programmed in the SAR block, the speed of the preceding block is valid. The velocity defined by
FAD
is not used
for following blocks.
18.5.4.3 Velocities
Velocities at approach
In both approach diagrams below, it is assumed that no new velocity is programmed in the block following the
SAR block. If this is not the case, the new velocity comes into effect after point P
4
.
