● SD42010 = < 0 to -1:
Starting/braking of the feedrate axis at configured acceleration rate. Jerk according to
current BRISK/SOFT programming.
● SD42010 = 0:
Abrupt starting/braking of the feedrate axis on thread cutting.
● SD42010 = > 0:
The thread run-up/deceleration distance is specified. To avoid technology alarm 22280,
the acceleration limits of the axis must be observed in case of very small run-in and run-
out paths.
Note
DITE acts at the end of the thread as an approximate distance. This achieves a smooth
change in the axis movement.
Pitch change F with G34, G35
If you already know the starting and final lead of a thread, you can calculate the pitch change
F to be programmed according to the following equation:

24.1.2 Feedrate for G63 (tapping with compensation chuck)
Note
The tapping function with compensation chuck is not available for versions G/N plus and pro.
Feedrate F
In the case of G63 it is necessary to program a feedrate F. It must be suitable for the
selected spindle speed S (programmed or set) and for the pitch of the drill:
Feedrate F [mm/min] = speed S [rev/min] x pitch [mm/rev]
