You can adjust the feed rate and spindle speed with the
override knobs.
It is possible to reduce the feed rate when starting the NC
program using the FMAX soft key. The reduction applies
to all rapid traverse and feed rate movements. The value
you enter is no longer in effect after the machine has been
turned off and on again. In order to re-establish the
respectively defined maximum feed rate after switch-on,
you need to re-enter the corresponding value.
The behavior of this function varies depending on the
respective machine. Refer to your machine tool manual.
