9.8 Block search Type 5 (SERUPRO)
The effects of this signal on the relevant axis are as follows:
Value 0:
Value 1:
Range of validity
Interface signal:
DB31, ... DBX70.0 (REPOS offset)
is supplied at the end of the SERUPRO operation.
The REPOS offset is invalidated at the start of a SERUPRO ASUB or the automatic ASUB
start.
Updating the REPOS offset within the scope
Between the SERUPRO end and SERUPRO start, the axis can be moved in JOG mode with
a mode change.
In JOG mode, the user manually moves the axis over the REPOS offset path in order to set
interface signal:
DB31, ... DBX70.0 (REPOS offset) to the value 0.
Within the range of validity, the axis can also be traversed using FC18, whereby the IS
DB31, ... DBX70.0 (REPOS offset) is continuously updated.
Displaying the range of validity
The range of validity of the REPOS offset is indicated with interface signal:
DB31, ... DBX70.1 (REPOS offset valid)
It is indicated whether the REPOS offset calculation was valid or invalid:
Value 0:
Value 1:
REPOS offset after an axis interchange
The group signal:
DB21, ... DBX319.5 (Repos DEFERRAL Chan)
can be used to determine whether a valid REPOS offset has taken place:
Value 0:
Value 1:
504
No REPOS offset is applied.
REPOS offset is applied.
The REPOS offset of this axis is calculated correctly.
The REPOS offset of this axis cannot be calculated, as the REPOS has not yet
occurred, e.g. it is at the end of the ASUB, or no REPOS is active.
All axes currently controlled by this channel have either no REPOS offset or their
REPOS offsets are invalid.
Miscellaneous.
