2.6 Block search Type 5 SERUPRO
2.6.8.8 REPOS offset in the interface
REPOS offset provided or valid
When the SERUPRO operation is finished, the user can use the OPI to read off the REPOS
offset applied via the REPOS process.
An axial interface bit is offered for this
DB31, ...DBX70.0 (REPOS offset).
Value 0 No REPOS offset has to be applied to this axis
Value 1 A REPOS offset has to be applied to this axis.
Scope: The axis-VDI-interface bit "REPOS offset" is provided when the SERUPRO operation
is finished. The "REPOS offset" is invalid when a SERUPRO ASUB starts or continues. The
axis can be moved in JOG mode with a mode change between the SERUPRO end and start
and the "REPOS offset" bit is continuously updated (i.e., the user traverses the REPOS
offset by hand and the bit changes to 0). In the scope, the axis can also be traversed using
FC18, with the "REPOS offset" continuously being updated.
The scope of "REPOS offset" is displayed with the axial VDI interface bit
DB31, ...DBX70.1 (REPOS offset valid):
Value 0 DB31, ... DBX70.0 (REPOS offset) has not been calculated as valid
Value 1 DB31, ... DBX70.0 (REPOS offset) has been calculated as valid
2.6.8.9 Making the initial settings more flexible
Initial setting/initial SERUPRO setting
Machine data MD20112 $MC_START_MODE_MASK defines the initial setting of the control
for part program start with respect to the G codes (especially the current plane and settable
zero offset), tool length compensation, transformation, and axis couplings. The special option
exists for the SERUPRO operation of using
MD22620 $MC_ENABLE_START_MODE_MASK_PRT
to select an initial setting that differs from the normal part program start. The new setting
must therefore been stored in:
MD22620 $MC_START_MODE_MASK_PRT
The meaning of the bits of MD22620 is identical to those of:
MD20112 $MC_START_MODE_MASK.
Example:
The synchronous spindle coupling at the beginning of the SERUPRO operation is retained
for the part program start.
$MC_START_MODE_MASK = 'H400'
$MC_START_MODE_MASK_PRT = 'H00'
$MC_ENABLE_START_MODE_MASK_PRT = 'H01'

Basic logic functions: Mode group, channel, program operation, reset response (K1)
; synchronous spindle coupling not
configured
; is switched off
; remains active
; $MC_START_MODE_MASK_PRT is
evaluated in SERUPRO instead of
$MC_START_MODE_MASK
