Accelerate Block Search - Siemens SINUMERIK 840D sl Function Manual

K1: Mode group, channel, program operation, reset response
9.8 Block search Type 5 (SERUPRO)
Specifying the REPOS mode via the NC/PLC interface
The REPOS mode can be specified via the following NC/PLC interface signal:
DB21, ... DBX31.0 - .2 (REPOS mode A, B, C)
Note
RMNBL is a general REPOS extension and it is not restricted to SERUPRO.
RMIBL and RMBBL behavior identically for SERUPRO.
DB21, ... DBX31.0 - .2 (REPOS mode) affects only the traversing motion of the path axes.
The behavior of the other axis can be changed individually using interface signal DB31, ...
DBX10.0 (REPOSDELAY). The REPOS offset is not applied immediately, but only when it is
next programmed.
For further information on the programming of the repositioning point, see:

Machine data settings
The speed of execution of the SERUPRO operation can be influenced via the following
machine data.
MD22600 $MC_SERUPRO_SPEED_MODE = <value>
<value>
506
Meaning
0 Program test with block search/dry run feedrate:
● Axes: MD22601 $MC_SERUPRO_SPEED_FACTOR * dry run feedrate
● Spindles: MD22601 $MC_SERUPRO_SPEED_FACTOR * programmed speed
Dynamic limitations of axes / spindles are not considered.
1 Program test with programmed velocity:
● Axes: Dry run feedrate
● Spindles: Programmed speed
Dynamic limitations of axes / spindles are considered.
