SERUPRO approach
The user can change the REPOS behavior of individual axes at specific times to reposition
certain axis types either earlier, later, or not at all. This affects SERUPRO approach in
particular. Repositioning movements of some axes can also be controlled independently of
SERUPRO approach during the REPOS operation.
Caution
The REPOS operation moves all axes from the current position to the start of the target
block in a single block with the appropriate setting of machine data:
MD11470 $MN_REPOS_MODE_MASK Bit 3.
During this process, the NC cannot detect any possible collisions with the machine or the
workpiece!
Protection zones and software limits are monitored.
Set REPOS response
Machine data:
MD11470 $MN_REPOS_MODE_MASK
can be used to set bits that specify the behavior of the NC during repositioning.
Bit 0 = 1
Bit 1 = 1
Bit 2 = 1
Bit 3 = 1
Bit 4 = 1
Bit 5 = 1
Bit 6 = 1
Bit 7 = 1

The dwell time is resumed at the point of interruption in the residual repositioning
block.
Reserved
Prevent repositioning of individual axes using VDI signals.
Reposition positioning axes in the approach block during block search via program
test (SERUPRO).
Positioning axes in approach block on every REPOS.
Modified feedrates and spindle speeds are valid immediately in the residual block.
Otherwise, not until the next block.
After SERUPRO, neutral axes and positioning spindles in the approach block are
repositioned as command axis.
The level of interface signal:
DB31, ... DBX10.0 (REPOSDELAY)
is read if REPOSA is interpreted.
Axes, which are neither geometry axes nor orientation axes, are then excluded from
the REPOS and are not moved.
