Description: Sets the actual system of units.
Value: 1: SI system of units
2: System of units referred/SI
3: US system of units
4: System of units referred/US
Dependency: The parameter can only be changed in an offline project using the commissioning software.
CAUTION
If a per unit representation is selected and if the reference parameters (e.g. p2000) are subsequently changed, then
the physical significance of several control parameters is also adapted at the same time. As a consequence, the
control behavior can change (see p1744, p1752, p1755).
Note
Reference parameter for the unit system % are, for example, p2000 ... p2004. Depending on what has been selected,
these are displayed using either SI or US units.

Description: Sets the reference values for the specific scaling of BICO parameters.
The specific scaling is active when interconnecting with other BICO parameters, and can be used in the following
cases:
1. Parameter with the marking "Scaling: p0514".
2. Changing the standard scaling for parameters with the marking "Scaling: p2000" ... "Scaling: p2007".
Relative values refer to the corresponding reference value. The reference value corresponds to 100% or 4000 hex
(word) or 4000 0000 hex (double word).
To specifically scale BICO parameters, proceed as follows:
- set the reference value (p0514[0...9]).
- set the numbers of the parameters, which should be active for the scaling, corresponding to the index of p0514
(p0515[0...19] ... p0524[0...19]).
For parameters with the marking "Scaling: p0514", which are not entered in p0515[0...19] to p0524[0...19], the
reference value 1.0 (factory setting) applies.
Index: [0] = Parameters in p0515[0...19]
