4.11 Feed Rate, Shaft Speed

Speed limitation G26

G26: Main spindle; Gx26: Spindle x (x: 1...3)
The speed limitation remains in effect until the end of the program or
until a new value is programmed for G26/Gx26.
Parameter
S (Maximum) speed
If S > "absolute maximum speed" (machine parameter),
the parameter value will apply.

Interrupted feed G64

G64 interrupts the programmed feed for a short period of time. G64 is
a modal function.
Parameters
E Interval time (0.01 s < E < 99.99 s)
F Feed period (0.01 s < E < 99.99 s)
For switch-on, program G64 with E and F.
For switch-off, program G64 without parameters.
