Block search
In the case of a search for a block containing a nibbling function, it is possible to program
whether the punch stroke is executed at the block beginning or suppressed.
The setting is programmed in machine data:

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 a rate of 25%.
