Nt_Close_Chain_T - Siemens SINUMERIK 840DE sl Function Manual

4.2.4.14

$NT_CLOSE_CHAIN_T

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 tool reference point is closed if $NT_CNTRL, Bit 8 == 1
($NT_CNTRL (Page 298)), 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 8, at the end of the last element (tool reference point).
Syntax
$NT_CLOSE_CHAIN_T[<n>] = "<ElementName>"
Meaning
$NT_CLOSE_CHAIN_T:
<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 tool reference point is closed, is: "T_Offset_3"
Program code
N100 $NT_CLOSE_CHAIN_T[1] = "T_Off-
set_3"
