Description: Sets the reference quantity for voltages.
All voltages specified as relative value are referred to this reference quantity. This also applies for direct voltage val-
ues (= rms value) like the DC-link voltage.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
Dependency: p2001 is only updated during automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning has been carried
out first for drive data set zero and as a result overwriting of the parameter has not been blocked by setting p0573 =
1.
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
For infeed units, the parameterized device supply voltage (p0210) is pre-assigned as the reference quantity.
Example:
The actual value of the DC link voltage (r0070) is connected to a test socket (e.g. p0771[0]). The actual voltage
value is cyclically converted into a percentage of the reference voltage (p2001) and output according to the param-
eterized scaling.
Description: Sets the reference quantity for currents.
All currents specified as relative value are referred to this reference quantity.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
Dependency: p2002 is only updated during automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning has been carried
out first for drive data set zero and as a result overwriting of the parameter has not been blocked by setting p0573 =
1.
Notice: If various DDS are used with different motor data, then the reference quantities remain the same as these are not
changed over with the DDS. The resulting conversion factor must be taken into account.
Example:
p2002 = 100 A
Reference quantity 100 A corresponds to 100 %
p305[0] = 100 A
Rated motor current 100 A for MDS0 in DDS0 --> 100 % corresponds to 100 % of the rated motor current
p305[1] = 50 A
Rated motor current 50 A for MDS1 in DDS1 --> 100 % corresponds to 200 % of the rated motor current
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
For infeed units, the rated line current, which is obtained from the rated power and parameterized rated line supply
voltage (p2002 = r0206 / p0210 / 1.73) is pre-assigned as the reference quantity.
Example:
The actual value of a phase current (r0069[0]) is connected to a test socket (e.g. p0771[0]). The actual current
value is cyclically converted into a percentage of the reference current (p2002) and output according to the param-
eterized scaling.
