2 Parameters
2.2 List of parameters
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
The following applies: Reference frequency (in Hz) = reference speed (in ((rpm) / 60) x pole pair number)
Dependency:
Refer to: p2001, p2002, p2003, r2004
Note:
For the automatic calculation (p0340 = 1, p3900 > 0) an appropriate pre-assignment is only made if the parameter is
not inhibited from being overwritten using p0573 = 1.
If a BICO interconnection is established between different physical quantities, then the particular reference quantities
are used as internal conversion factor.
Example 1:
The signal of an analog input (e.g. r4055[0]) is connected to a speed setpoint (e.g. p1070[0]). The actual percentage
input value is cyclically converted into the absolute speed setpoint using the reference speed (p2000).
Example 2:
The setpoint from PROFIBUS (r2050[1]) is connected to a speed setpoint (e.g. p1070[0]). The actual input value is
cyclically converted into a percentage value via the pre-specified scaling 4000 hex. This percentage value is
converted to the absolute speed setpoint via reference speed (p2000).

Reference voltage / Reference voltage

B_INF, VECTOR_G
Can be changed: T
Data type: FloatingPoint32
P-Group: Communications
Not for motor type: -
Min
10 [Vrms]
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
values (= rms value) like the DC-link voltage.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
Note:
This reference quantity also applies to direct voltage values. It is not interpreted as rms value, but as DC voltage
value.
Note:
For the automatic calculation (p0340 = 1, p3900 > 0) an appropriate pre-assignment is only made if the parameter is
not inhibited from being overwritten using p0573 = 1.
If a BICO interconnection is established between different physical quantities, then the particular reference quantities
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 parameterized
scaling.
p2002

Reference current / I_ref

B_INF, VECTOR_G
Can be changed: T
Data type: FloatingPoint32
P-Group: Communications
Not for motor type: -
Min
0.10 [Arms]
Description:
Sets the reference quantity for currents.
All currents specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
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 should be taken into account (e.g. for trace records).
Example:
p2002 = 100 A
Reference quantity 100 A corresponds to 100 %
p0305[0] = 100 A
Rated motor current 100 A for MDS0 in DDS0 --> 100 % corresponds to 100 % of the rated motor current
