Parameters
7.3 Parameters
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
Can be changed: T
Unit group: -
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.
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
Can be changed: T
Unit group: -
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).
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.
