Programming the feedrate with FAD
FAD programmed with ...
G340
G341
If FAD is not programmed, this part of the contour is traversed at the velocity, which is active
modally from the preceding block, in the event that no F command defining the velocity is
programmed in the SAR block.
Programmed response:
FAD=0 or negative
FAD=...
FAD=PM(...)
FAD=PR(...)
Example:
$TC_DP1[1,1]=120
$TC_DP6[1,1]=7

→ Alarm Output
→ Programmed value acts in accordance with the active G code of
group 15 (feed type; G93, G94, etc.)
→ Programmed value is interpreted as linear feed (like G94), irre‐
spective of the active G code of group 15
→ Programmed value is interpreted as revolutional feed (like G95),
irrespective of the active G code of group 15
or P to P .
