DBX70.1 REPOS offset valid
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The range of validity of the REPOS offset is indicated with the value 1.
The REPOS offset was calculated to be valid.
Signal state 0 or
edge change
1 → 0
A value of zero indicates that the REPOS offset was calculated to be invalid.
Application
example(s)
Updating the REPOS offset in the range of validity:
Between SERUPRO end and start, the axis can be moved in JOG mode with a mode change. The
user moves the REPOS offset to the zero value.
Corresponds to.... DB31, ... DBX70.0 (REPOS offset)

DBX70.2 REPOS Delay Ackn
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The axis was programmed within a traversing block, and the REPOS offset was applied.
Note
A REPOS offset was available for the axis, and REPOSDELAY was active:
DB31, ... DBX10.0 (REPOSDELAY) == 1
This signal behaves the same as:
DB21, ... DBX319.1 - DBX319.3 (Repos Path Mode Ackn)
Signal state 0 or
edge change
1 → 0
The value zero is used to acknowledge that the REPOS offset is not active for this axis. This signal
is cancelled on activation of the remaining block.
Corresponds to.... DB31, ... DBX10.0 (REPOSDELAY)
DB31, ... DBX72.0 (REPOSDELAY)
DB31, ...
DBX72.0 REPOSDELAY
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
After a block search, a REPOS offset is applied for this axis. However it is not applied using the
approach block, but rather using the next traversing block in which the axis is programmed.
Signal state 0 or
edge change
1 → 0
The REPOS offset for this axis is not active.
Special cases,
errors, ......
The signal is not relevant for path axes.
Corresponds to.... DB21, ... DBX31.0 - DBX31.2 (REPOSPATHMODE)
DB31, ... DBX10.0 (REPOSDELAY)
DB31, ... DBX70.2 (REPOS Delay Ackn)
