Programming of Traversing Blocks
4.11.3 Loop-over window 1 or 2 (G66, G67)
Block change at the braking point G64 leads to fast sequences of movements, but the large
loop-over results in a great deviation from the programmed path. Block change with exact stop
G60 guarantees that the positions are exactly reached, but the positioning time is increased
because sequences of movements are again and again passed to the PEH window and,
therefore, stopped.
For a more flexible programming, the WF 723 C offers two loop-over windows. For loop-over,
two dimensions can be defined, which lie between the braking point
➀
and the exact stop
➁
.
G66 activates the loop-over window 1 (MD46), G67, the loop-over window 2 (MD47). G66 and
G67 are modally effective.

Range for loop-over window
If the loop-over window is larger than the actual value at the braking point
(
➀
), the block will be changed in the braking point. If the loop-over
window is smaller than the PEH window (
➁
), block change will take
place, like with exact stop G60, as soon as the PEH window is reached.
