K12 transformation definitions with kinematic chains
4.2 Commissioning
Meaning
$NT_T_REF_ELEM:
<n>:
<RefElementName>:
Example
For the first transformation, the name of the element of the kinematic chain that is currently in
effect, which defines the tool reference position, is "ToolRefPoint":
Program code
N100 $NT_T_REF_ELEM[1] = "ToolRef-
Point"
4.2.4.10

$NT_GEO_AX_NAME

Function
A maximum of three names ($NT_NAME (Page 279)) of the elements of the kinematic chain
that is currently in effect, which define the geometry axes (linear axes) of the transformation
type (Page 256) to be parameterized, must be entered in the system variable. The geometry
axes carry out the linear compensating movements, which result from the kinematic
transformation.
Syntax
$NT_GEO_AX_NAME[<n>,<k>] = "<GeoAxElementName>"
