You can change the feed rate and spindle speed
using the potentiometers.
If you want to retract the NC Program, you can
reduce the feed rate using the FMAX soft key.
The reduction applies to all infeed 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 The value you enter is no longer in
effect after the machine has been turned off and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 respective
specified 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 manual.
