3.4.3.2 Application parameters
Application parameters describe the basic conditions under which a Motion App is to be executed,
using attributes such as mass during retracting and advancing, travel time, and acceleration. Here, the
application parameters of a parameter set can be individually adapted for each Motion App (
è
3.4.3.9
Parameter sets). This means that, for example, the “mass during retracting” can be defined differently
for different Motion Apps on the same valve.
Not all Motion Apps use application parameters.
The parameters required to run a Motion App must be transferred before starting the Motion App.
