Default zero offset
The active NPV after program start is parameterisable (P-ZERO-00002).
In the NC program, the operator can use the V.G.NP_DEFAULT variable to access the default index. The change is valid across all programs.
Programing Example
Starting with this program line, G55 (NPV2) will be the new default NPV. This means that G55 is automatically active at next program start.
N100 V.G.NP_DEFAULT = 2
