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.
• It does not interrupt the execution of function G74 (home search).
• It has no effect when tangential control is active.
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.
ACTGAINT (M5063)
The axes and the spindle can have 3 sets of gains and accelerations.
By default, the first set is always assumed. The one indicated by the axis and spindle parameters:
ACCTIME (P18), PROGAIN (P23), DERGAIN (P24) and FFGAIN (P25).
general parameter ACTGAINT (P185) indicates with which functions or in which mode the third set
is applied, the one set by axis parameters ACCTIMET (P92), PROGAINT (P93), DERGAINT (P94)
and FFGAINT (P95) or spindle parameters ACCTIMET (P81), PROGAINT (P82), DERGAINT (P83)
and FFGAINT (P84).
The gains and accelerations can also be changed from the PLC regardless of the active operating
mode or function. To do this, use general input ACTGAINT (M5063).
ACTGAINT (M5063) = 1 The CNC assumes the third set.
Path 1 Path 2
The solid lines represent the programmed paths and the dashed lines the real paths,
after activating the BLOABOR mark.
The change of gains and accelerations is always made at the beginning of the block.
When working in round corner (G5), the change does not take place until G07 is programmed.
