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
Fig. 8-37 Proportional increase in acceleration from 50 to 100 % with a distance between holes of 2
mm to 10 mm
The characteristic shown in the illustration above defines the following acceleration rate:
S Distance between the holes less than 2 mm: The axis accelerates at a rate correspond-
ing to 50 % of maximum acceleration.
S Distance between the holes between 2 mm and 10 mm: Acceleration is increased to
100 %, proportional to the spacing.
S Distance between the holes greater than 10 mm: The axis accelerates at the maximum
rate (100 %).
Example 2
Fig. 8-38 Proportional increase in acceleration from 75 to 25 % with a distance between holes of 3
mm to 8 mm
