Punching and Nibbling (N4)
10.3 Activation and deactivation
Example 2
The characteristic defines the following acceleration rates:
Distance between
holes
< 3 mm
3 - 8 mm
> 10 mm (2.05 in)
If a reduced acceleration rate has already been programmed via ACC, then the acceleration
limits defined with PUNCHACC refer to the reduced acceleration rate.
The function is deselected with:
S
min
The acceleration rate programmed beforehand with ACC remains operative.

Acceleration
The axis accelerates at a rate corresponding to 75 % of maximum acceleration.
Acceleration is reduced to 25 %, proportional to the spacing.
The axis accelerates at the maximum rate (25 %).
