REPOS display Offset
Once the search target has been found, for each axis of the
FXS
-state prevailing on the machine through the
axis VDI-signals:
IS DB31, ... DBX62.4 ("Activate travel to fixed stop")
and
IS DB31, ... DBX62.5 ("Fixed stop reached")
displayed.
Example:
If the machine is at the fixed stop and the block search has reached a block after deselection of
FXS
, the new
target position is displayed via IS DB31, ... DBX62.5 ("Fixed stop reached") is displayed as
REPOS
offset.
FXS fully automatically in REPOS
With
REPOS
the functionality of
FXS
is repeated automatically and designated
FXS-REPOS
below. This
sequence is comparable to the program "fxsSeruproAsup.mpf." Every axis is taken into account and the torque
last programmed before the search target is applied.
The user can treat
FXS
separately in a SERUPRO-ASUP.
The following then applies:
Every
FXS
action executed in SERUPRO-ASUP automatically takes care of
$AA_FXS[X] == $VA_FXS[X].
This deactivates
FXS-REPOS
for axis X.
Deactivate FXS REPOS
FXS-REPOS
is deactivated by:
• an
FXS
synchronous action which refers to
REPOSA
Or
• $AA_FXS[X] == $VA_FXS[X] in SERUPRO_ASUP.
Note
A SERUPRO-ASUP without
FXS
handling or no SERUPRO-ASUP results in fully
automatic
FXS-REPOS
.
CAUTION
FXS-REPOS
moves all path axes in a path grouping to the target position. Axes with and
without
FXS
treatment thus traverse together with the G code and feedrate valid at the
time the target block is processed. As a result, the fixed stop may be approached in rapid
traverse(
G0
) or higher velocity.
