Note
Second gear-stage data block
To achieve effective adaptation of spindle speed and motor torque and be able to accelerate
faster, a second gear-stage data block for two further configurable switching thresholds
(maximum speed and minimum speed) can be preset in axis-specific machine data deviating
from the first gear step data block and also independent of these speed switching thresholds.
The specifications of the machine manufacturer must be observed.
For further information see the "Axes and Spindles" Function Manual.
Examples
● Example: Tapping with G331 / G332 (Page 765)
● Example: Output the programmed drilling speed in the current gear stage (Page 765)
● Example: Application of the second gear-stage data block (Page 766)
● Example: Speed is not programmed, the gearbox stage is monitored (Page 766)
● Example: Gearbox stage cannot be changed, gearbox stage monitoring (Page 766)
● Example: Programming without SPOS (Page 767)

Tapping
The tapped hole is defined by the traversing motion of the axis (drilling depth)
and the thread pitch.
Effectiveness: Modal
Retraction motion when tapping
Retraction motion must have the same pitch as when tapping (G331). The
direction of rotation of the spindle is reversed automatically.
Effectiveness: Modal
Traversing distance/position of the geometry axis (X, Y or Z) at the end of the
thread, e.g. Z50
Thread pitch I (X), J (Y) or K (Z):
● Positive pitch: Right-handed thread, e.g. K1.25
● Negative pitch: Left-handed thread, e.g. K-1.25
Range of values: ±0.001 to ±2000.00 mm/revolution
Spindle speed
The last active spindle speed is used if a spindle speed is not specified.
