10.4.3 Response in connection with single axes
MD26016
The path of single axes programmed in addition to path axes is distributed evenly among the
generated intermediate blocks as standard.
In the following example, the additional rotary axis C is defined as a synchronous axis.
If this axis is programmed additionally as a "Punch-nibble axis":
MD26010 $MC_PUNCHNIB_AXIS_MASK = 1,
then the behavior of the synchronous axis can be varied as a function of machine data:
MD26016 $MC_PUNCH_PARTITION_TYPE.
Programming example:
N10 G90 G1 PON X10 Y10 C0 F10000
N20 SPP=5 X25 C45
N30 G3 SPN=3 X35 Y20 I0 J10 C90
MD26016 $MC_PUNCH_PARTITION_TYPE=0 (default setting)
With this setting, the axes behave as standard, i.e. the programmed special axis motions are
distributed among the generated intermediate blocks of the active path segmentation
function in all interpolation modes.
In block N20, the C axis is rotated through 15° in each of the three intermediate blocks.
The axis response is the same in block N30, in the case of circular interpolation (three sub-
blocks, each with 15° axis rotation).
