and Spindle Speed
6.6 Feed Rate and Spindle Speed
Speed limitation G26/G126
The speed limit remains in effect until a new value is programmed for
G26/G126.
Parameters
 S speed: Maximum speed
Interrupted feed G64
G64 interrupts the programmed feed for a short period of time. This
function is used to ensure continuous chip breaking.
G64 without parameters deactivates the interrupted (intermittent)
feed rate.
Parameters
 E pause duration: Range: 0.01s < E < 999s
 F feed duration: The slide accelerates to the programmed feed
rate and decelerates again to "zero feed" at the end of the period.
Range: 0.01s < E < 999s

G26: Speed limitation for spindle
G126: Speed limitation for spindle 1 (driven tool)
„ The speed limitation remains in effect even after
concluding the DIN program and exiting "Program run"
mode. You can define a new speed limit in the "F, S, T
menu" or via parameters.
„ If the speed programmed with G26/G126 is greater than
the speed set in the machine parameter "General
parameters for spindle—Absolute max. speed," then the
speed limit of this parameter takes effect.
