Blocked parameters
Parameters can be locked in the parameter view to prevent changes. In this case, they are
marked with the symbol
● When the parameter has been set by means of a previous basic parameterization (such
as in the device configuration) and a parameter change would take effect later with an
altered structure.
● For parameters that are generally not to be manually changed by the user, for example

● For parameters that are generally only to be configured in Startdrive via input screens.
The display in the parameter view then only serves as an overview.
