$NT_CLOSE_CHAIN_P

Function
The name ($NT_NAME (Page 279)) of the element of the currently active kinematic chain, at
the end of which the subchain for the workpiece reference point is closed if $NT_CNTRL, Bit 7
== 1, can be entered in the system variable.
If no name is entered in the system variable, the subchain is closed independently of
$NT_CNTRL, Bit 7, at the end of the last element (workpiece reference point).
Syntax
$NT_CLOSE_CHAIN_P[<n>] = "<ElementName>"
Meaning
$NT_CLOSE_CHAIN_P:
<n>:
<ElementName>:
Example
For the first transformation, the name of the element of the kinematic chain, at the end of which
the part chain for the workpiece reference point is closed, is: "P_Offset_3"
Program code
N100 $NT_CLOSE_CHAIN_P[1] = "P_Off-
set_3"
