Detailed Description
2.6 Block search Type 5 SERUPRO
Interface signal:
DB31, ... DBX70.2 (Repos Delay Ackn)
is defined in the same way.
DB31, ... DBX70.1 (Repos offset valid) =1
if:
DB21, ... DBX319.1-319.3 (Repos Path Mode Ackn0 to 2) = 4 (RMN).
Valid REPOS offset
When the SERUPRO operation is complete, the user can read out the REPOS offset via the
axis/spindle VDI signal (NCK→PLC):
DB31, ... DBX70.0 (REPOS offset).
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 DB31, ...
DBX70.0 is continuously updated.
2-52
No REPOS offset is applied.
