Variable
$NT_BASE_TOOL_COMP
$NT_ROT_AX_OFFSET[n, 0....2]
"x" affects the transformation.
"-" has no effect on the transformation
"~" has no effect on the transformation in the NCK, but can be properly used for purposes outside of NC.
"Numbers" permitted axis indices (0 to 2)
"Column index"; column index of the variables in the operator panel interface in block N_PA (0x35).

Importing the rotary axis offset from the work offset upon selection
of the transformation:
Defines whether the tool length is handled in the transformation or
- if the transformation permits it - outside of the transformation.
Auxiliary position for cycles, e.g. retraction position
Note Has no meaning for the transformation
Identification number for user-specific program management
