Parameterisation
Compared to the representation in section (
è
3.4.3 Parameter), the value ranges for the parameters
may be restricted by the specific Motion App. The specific value ranges for the Motion Apps are
described in the manuals for the various Motion Apps.
If a system parameter is outside the valid value range for a Motion App to be started because it was
set for another Motion App or with addressed target = 0, an error is returned if an attempt is made to
start the Motion App.
Example
The system parameter "Tubing internal diameter at (2)" (ID 14) should be parameterised in parameter
set 2 in order for a tubing internal diameter of 5.7 mm to be used from Motion App #04.
