DBX70.1 REPOS offset valid
Signal state 0 or A value of zero indicates that the REPOS offset was calculated to be invalid.
edge change
1 → 0
Application exam‐ Updating the REPOS offset in the range of validity:
ple(s) 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)
DB31, ...
DBX70.2 REPOS Delay Ackn
Edge evaluation: no
Signal state 1 or The axis was programmed within a traversing block, and the REPOS offset was applied.
edge change
Note
0 → 1
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 The value zero is used to acknowledge that the REPOS offset is not active for this axis. This signal
edge change is cancelled on activation of the remaining block.
1 → 0
Corresponds to .... DB31, ... DBX10.0 (REPOSDELAY)
DB31, ... DBX72.0 (REPOSDELAY)
DB31, ...
DBX72.0 REPOSDELAY
Edge evaluation: no
Signal state 1 or After a block search, a REPOS offset is applied for this axis. However it is not applied using the
edge change approach block, but rather using the next traversing block in which the axis is programmed.
0 → 1
Signal state 0 or The REPOS offset for this axis is not active.
edge change
1 → 0
Special cases, The signal is not relevant for path axes.
