BLOABORP (M5061)
It is similar to general logic input BLOABOR (M5060), but for the PLC channel.
When the PLC sets this mark high, the CNC ends the movement in progress and starts executing
the next block. If the interrupted block had M functions to be executed after the block, they will be
executed before going on to the next block.
This mark only affects the execution in automatic mode and the simulation with motion.
This mark does not stay active after the execution. Once executed, the CNC deactivates it. Likewise,
if they are activated in a block that does not accept them, they will also be deactivated; they do not
stay active for the next block.
These marks affect the following functions.
• It affect motion blocks G0, G1, G2, G3.
• They affect the dwell programmed with G4.
• It affects the look-ahead. In this type of programs with very small blocks, it is not possible to stop
at the same block where the "BLOABOR" mark is detected. In these cases, it will be canceled
at the block where the axis is fully decelerated.
These marks do not affect the following functions.
• It does not affect motionless blocs, which will be executed.
• It does not affect the M functions that are executed after the block. These functions are always
executed, even if the movement of the block is interrupted.
• It does affect not affect threading blocks G33. Nor does it affect the regular tapping or rigid tapping
cycles regardless of the value of parameter STOPTAP.
• It does not affect spindle positioning blocks M19. If the spindle positioning is in a block containing
axis movement, it aborts the movement of the axes, but it completes the positioning of the
spindle.
Considerations for the execution
These marks do not affect block preparation. When canceling the execution of a block, the next
movement is carried out up to the prepared target coordinates; no preparation is done.
On the other hand, only the programmed axes are involved in the next movement. The rest of the
axes are ignored, even if there is a real difference in position because the previous block has been
aborted.
If a block is aborted and then the RETRACE function is activated, the retraced path (backwards)
will not be the same as the one traveled forward. The two paths will not coincide either when aborting
a block while the RETRACE function is active.
Path 1 Path 2
The solid lines represent the programmed paths and the dashed lines the real paths,
after activating the BLOABORP mark.
