: Feedrate modification in percent
The value refers to or is combined with the feedrate override set
on the machine control panel.
Range of values: ... 200%, integers
Note:
With path and rapid traverse override, the maximum velocities set
in the machine data are not overshot.
S
and are identical in terms of function.
S<n>
: Spindle number
converts spindle numbers into axis identifiers. The transfer
must contain a valid spindle number.
