Travel-dependent acceleration
An acceleration characteristic can be defined with PUNCHACC (Smin, Amin, Smax,
Amax). This command can be used to define different acceleration rates depending on the
distance between holes.
Example 1
The characteristic defines the following acceleration rates:
Distance
between holes
< 2 mm
2 - 10 mm
> 10 mm
(2.05 in)

Acceleration
The axis accelerates at a rate corresponding to 50 % of maximum acceleration.
Acceleration is increased to 100 %, proportional to the spacing.
The axis accelerates at the maximum rate (100%).
