230 ISO Programming
4.11 Feed Rate, Shaft Speed
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.
Interrupted feed G64
G64 interrupts the programmed feed for a short period of time. G64 is
a modal function.
For switch-on, program G64 with E and F.
For switch-off, program G64 without parameters.
Example: G26
. . .
N1 G14 Q0
N1 G26 S2000 [maximum speed]
N2 T3 G95 F0.25 G96 S200 M3
N3 G0 X0 Z2
. . .
Parameter
S (Maximum) speed
If S > “absolute maximum speed” (machine parameter),
the parameter value will apply.
