Note
$AC_BLOCKTYPEINFO also always includes the value for the block type in the thousands
position (T) in the case that there is an intermediate block. The thousands position is not
accepted in $AC_BLOCKTYPE not equal to 0.

ID application
Significance:
Unchanged programmed block (a block generated by the compressor is also dealt with as
a programmed block)
There is an internally generated block or a shortened original block
The last block in a chain of internally generated blocks or shortened original blocks is
available
E Meaning:
Trigger for intermediate block:
TLIFT block with:
1 Linear movement of tangential axis and without
lift motion
2 Nonlinear movement of tangential axis
(polynomial) and without lift motion
3 Lift movement, tangential axis movement and lift
movement start simultaneously
4 Lift movement, tangential axis does not start until
certain lift position is reached.
Path segmentation:
1 Programmed path segmentation is active without
punching or nibbling
2 Programmed path segmentation with active
punching or nibbling
3 Automatically, internally generated path
segmentation
Compile cycles:
ID of the compile cycle application that generated
the block
