$NT_ROT_AX_CNT

Function
The system variable $NT_ROT_AX_CNT provides the number of the relevant rotary axes in the
workpiece or in the tool chain. The relevant rotary axes in this sense are the rotary axes that are
defined in the system variable $NT_ROT_AX_Name.
Syntax
$NT_ROT_AX_CNT[<n,m>] = <NumberRotAxes>
Meaning
$NT_ROT_AX_CN
T:
<n>:
<m>:
Example
Provides the number of rotary axes for the subchain:
Program code
N100 $NT_ROT_AX_CNT[1,0] = 2
