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

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'
