Example: Axis is programmed incrementally
Axis A is positioned at 11° before the REPOS operation; the programmed operation in the
interruption block (target block for SERUPRO) specifies 27°.
Any number of blocks later, this axis is programmed incrementally by 5° using:
N1010 POS[A]=IC(5) FA[A]=1000
.
With the interface signal:
DB31, ... DBX10.0 (REPOSDELAY)
the axis does not traverse in the REPOS operation and is moved to 32° with N1010.
(The user may have to deliberately acknowledge the travel from 11° to 27°.)
Caution:
The axis is programmed incrementally after the interruption.
In the example, the NC moves to 16° (instead of 32°).
A) Start axes individually
The REPOS behavior for SERUPRO approach with several axes is selected with:
MD11470 $MN_REPOS_MODE_MASK BIT 3 == 1
The NC commences SERUPRO approach with a block that moves all positioning axes to the
programmed end and the path axis to the target block.
The user starts the individual axes by selecting the appropriate feedrate enables. The target
block motion is then executed.
B) Reposition positioning axes in the repositioning block
Positioning axes are not repositioned in the residual block but rather in the repositioning
block, and their effect is not limited to the block search via program test on SERUPRO
approach.
MD11470 $MN_REPOS_MODE_MASK
Bit 3=1
Bit 4=1
Note
If neither bit 3 nor bit 4 is set, "non-path axes" are repositioned in the residual block in this
phase.
