Unit
For SINAMICS G120, the units of a particular parameter involve the physical quantity (e.g.
m, s, A). Quantities are measurable properties/characteristics of physical objects, operations,
states and are represented using characters of a formula (e.g. V = 9 V).

Grouping
The parameters are sub-divided into groups according to their functionality. This increases
the transparency and allows a quicker and more efficient search for specific parameters.
Furthermore, parameter P0004 can be used to control the specific group of parameters that
are displayed on the OP.
