Siemens SINUMERIK 840D sl Function Manual page 197

Example
The 9th kinematic element is assigned the machine axis with the name V1 as linear axis.
Program code
N100 $NK_AXIS[8] = "V1"
$NK_A_OFF
Function
An additional work offset can be entered in the system variable for the assigned machine axis
($NK_AXIS). This work offset is only effective within the kinematic chain.
Syntax
$NK_A_OFF[<n>] = <value>
Meaning
$NK_A_OFF:
<n>:
<value>:
Example
The linear axis zero point of the 9th kinematic element is moved by 30.0 mm compared to the
modelled kinematics.
The unit in which the numerical value is interpreted depends on the current input system (inch/
metric).
Program code
N100 $NK_A_OFF[8] = 30.0
