SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the maximum flux setpoint to measure the saturation characteristic.
Description: Sets the reference quantity for speed and frequency.
All speeds or frequencies 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).
The following applies: Reference frequency (in Hz) = reference speed (in ((rpm) / 60) x pole pair number)
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.
Refer to: p2001, p2002, p2003, r2004, r3996
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 quanti-
ties 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 percent-
age 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 con-
verted to the absolute speed setpoint via reference speed (p2000).
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 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.
