Function
The DRF (Differential Resolve Function) offset allows an additional
incremental zero offset to be set using the handwheel. "DRF" is an
axial traverse that works in the basic coordinate system. The
handwheel selection is only permitted via the axial interface, i.e., only
machine axes can be used.
The DRF offset can be switched on and off for specific channels by
means of the "Program control" function.
It remains stored until
