5.2 Parameters
Change state
"P" parameters can only be changed depending on the inverter state. The parameter value is
not accepted if the instantaneous state is not listed in the parameter attribute "Change state".
For instance, the quick commissioning parameter P0010 with the attribute "CT" can only be
changed in quick commissioning "C" or ready "T" but not in operation "U".

Data types
The data type of a parameter defines the maximum possible value range. Five data types
are used for SINAMICS G120. They either represent an unsigned integer value (U16, U32)
or a floating-point value (float). The value range is frequently restricted by a minimum and
maximum value (min, max) or using inverter/motor quantities.
