Note
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. r0755[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).
p2001 Reference voltage / Reference voltage
Access level: 3 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
10 [Vrms] Max:
100000 [Vrms] Factory setting:
1000 [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.
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.

p2002 Reference current / I_ref
Access level: 3 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0.10 [Arms] Max:
100000.00 [Arms] Factory setting:
100.00 [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).
Dependency: This parameter is only updated during the automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning was
carried out beforehand for drive data set zero. This means that the parameter is not locked against overwriting using
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 %
p0305[0] = 100 A
Rated motor current 100 A for MDS0 in DDS0 --> 100 % corresponds to 100 % of the rated motor current
p0305[1] = 50 A
Rated motor current 50 A for MDS1 in DDS1 --> 100 % corresponds to 200 % of the rated motor current
When the reference current is changed, short-term communication interruptions may occur.
