Section 5
For the user it may be advantageous to switch on certain settings, that are
to be activated in the part program, already in the program heading.
If necessary, these modally operative commands can always be reset by
other commands at any stage during the program.

Note:
As the tool progresses towards the centre during facing, the spindle speed
evaluated internally in the control unit increases steadily until eventually
the maximum possible spindle speed would be attained.
Depending on the clamping conditions and the size of the work piece a
speed limitation should always be selected for reasons of safety.
* The explanation of the diameter input will be found in section 6 of this
manual.
