SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Enter the inductance of a filter connected at the power unit output.
Dependency: This parameter is automatically preset when you select a filter via p0230 if a SIEMENS filter is defined for the power
unit.
Refer to: p0230
Note: When exiting the quick commissioning using p3900 = 1, the parameter value is set to the value of the defined SIE-
MENS filter or to zero. For this reason, the parameter value of a third-party filter only has to be entered outside the
commissioning phase (p0010 = 0) and then the controller calculation (p0340 = 3) is carried out.
The parameter cannot be changed if the power unit (e.g. PM260) is equipped with an internal sine-wave filter.
Description: Enters the capacitance of a sine-wave filter connected at the power unit output.
Dependency: This parameter is automatically preset when you select a filter via p0230 if a SIEMENS filter is defined for the power
unit.
Refer to: p0230
Note: The parameter value includes the sum of all of the capacitances of a phase connected in series (phase - ground).
When exiting the quick commissioning using p3900 = 1, the parameter value is set to the value of the defined SIE-
MENS filter or to zero. For this reason, the parameter value of a third-party filter only has to be entered outside the
commissioning phase (p0010 = 0).
The parameter cannot be changed if the power unit (e.g. PM260) is equipped with an internal sine-wave filter.
Description: Displays the internal resistance of the power unit (IGBT and line resistance).
Note: For a parallel circuit, the value corresponds to the resistance of a power unit.
Index 0 refers to the first line filter from p0220[0].
Index 1 refers to the optional second line filter from p0220[1].
Description: Sets the absolute value by which the threshold to initiate the undervoltage fault (F30003) is reduced.
Dependency: Refer to: p0210, r0296
Refer to: F30003
Notice: When using a Control Supply Module (CSM) for 24 V supply from the DC link, the minimum continuous DC link volt-
age may not lie below 430 V. DC link voltages in the range 300 ... 430 V are permissible up to a duration of 1 min.
Note: The resulting shutdown threshold can be read in r0296 and is dependent on the selected rated voltage (p0210) and
the power unit being used.
