Implicit global subroutine call at program start

The same recurring initialisations of data must often be executed at the start of different NC main programs. If these initialisations are summarised in a global subroutine, this program can be executed implicitly as the first action at every NC program start with the channel parameter P-CHAN-00119.

The full scope of NC programming functions can be used in this global subroutine. This means that it behaves in the same way as a subroutines call with the L word in the main NC program.

Notice

This mechanism is primarily intended for initialisation, definition and presetting of offsets, G functions, parameter values, variables etc. Concrete machining processes should not be programmed here.
