Examples
● Example: Tapping with G331 / G332 (Page 241)
● Example: Output the programmed drilling speed in the current gear stage (Page 241)
● Example: Application of the second gear-stage data block (Page 242)
● Example: Speed is not programmed, the gearbox stage is monitored (Page 242)
● Example: Gearbox stage cannot be changed, gearbox stage monitoring (Page 243)
● Example: Programming without SPOS (Page 243)

2.9.11.3 Example: Output the programmed drilling speed in the current gear stage
Program code Comment
N05 M40 S500 ; Programmed spindle speed: 500 rpm =>
; Gearbox stage 1 (20 to 1028 rpm)
...
N55 SPOS=0 ; Position the spindle
N60 G331 Z-10 K5 S800 ; Tapping
; Spindle speed 800 rpm => gearbox stage 1
The appropriate gear stage for the programmed spindle speed S500 with M40 is determined on
the basis of the first gear-stage data block. The programmed drilling speed S800 is output in the
current gear stage and, if necessary, is limited to the maximum speed of the gear stage. No
