Meaning
$NK_AXIS:
<n>:
<value>:
Example
The 9th kinematic element is assigned the machine axis with the name B1 as rotary axis.
Program code
N100 $NK_AXIS[8] = "B1"
$NK_A_OFF
Function
An additional work offset can be entered in the system variable for the assigned machine axis
($NK_AXIS). This work offset is only effective within the kinematic chain.
Syntax
$NK_A_OFF[<n>] = <value>
