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
When the reference speed / reference frequency is changed, short-term communication interruptions may occur.
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.
