2 Parameters
2.2 List of parameters
Description: Enters the capacitance of a sine-wave filter connected at the power unit output.
Dependency: This parameter is automatically pre-set 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
SIEMENS 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: Sets the number of reactors connected in series at the power unit output.
Dependency: Refer to: p0230
Notice: The reactor inductances should be the same.
If the number of motor reactors connected in series does not correspond to this parameter value, then this can result
in an unfavorable control behavior.
Description: Displays the internal resistance of the power unit (IGBT and line resistance).
Description: Sets the configuration for the output voltage measurement of the power unit.
Note: The motor data identification must be executed when using the voltage measurement.
