Implicit global sub-routine call at program start

Often during start of different NC main programs the same recurring initializations of data must be executed. If this initializations are summarized in a global sub-routine, with channel parameter [1]-44 it is possible, that this sub-routine is implicitly executed as a first action at NC program start [CHAN].

In this sub-routine the complete functional scope of the NC programming can be used. This means, it is the same like a sub-routine call with the L word in the main program.

Above all this feature is useful for initialization, definition and presetting of offsets, G functions, parameter value, variables and so on. Concrete steps of operation should not be programmed here.
