drives
The values are displayed in the corresponding sections of the input data (PDI) for confirmation
(

Tab. 60 Structure of the input data (PDI)).
With the description and use of a user-defined drive the user must always ensure that the set
parameters are complete and correctly describe the actual drive.
4.5 Save parameterisation as persistent data
Saving parameterisation on the Motion Terminal controller as persistent data is described in section:
(
