Siemens SINAMICS G120 List Manual page 57

p0230 = 4:
--> p0290 (power unit overload response) = inhibit pulse frequency reduction
--> p1802 (modulator modes) = space vector modulation without overcontrol
The user must set the following parameters according to the data sheet of the sine-wave filter and also the user must
check whether they are permitted.
--> p0233 (power unit, motor reactor) = filter inductance
--> p0234 (power unit sine-wave filter capacitance) = filter capacitance
--> p1082 (maximum speed) = Fmax filter / pole pair number
--> p1800 (pulse frequency) >= nominal pulse frequency of the filter
Refer to: p0233, p0234, p0290, p1082, p1800, p1802
Note: The parameter cannot be changed if the power unit (e.g. PM260) is equipped with an internal sine-wave filter.
For sine-wave filters, the test pulse evaluation to detect short-circuits is always de-activated.
If a filter type cannot be selected, then this filter type is not permitted for the power unit.
p0230 = 1:
Power units with output reactor are limited to output frequencies of 150 Hz.
p0230 = 3:
Power units with sine-wave filter are limited to output frequencies of 200 Hz.
r0231[0...1] Power cable length maximum / Cable length max
Access level: 3
Can be changed: -
Unit group: -
Min
- [m]
Description: Displays the maximum permissible cable lengths between the drive unit and motor.
Index: [0] = Unshielded
[1] = Shielded
Note: The display value is used to provide information for service and maintenance.
p0233 Power unit motor reactor / PU mot reactor
Access level: 2
Can be changed: C(2), U, T
Unit group: -
Min
0.000 [mH]
Description: Enter the inductance of a 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: 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) and then the controller calculation (p0340 = 3) is carried out.
The parameter cannot be changed if the power unit has an internal sine-wave filter.
p0234 Power unit sine-wave filter capacitance / PU sine filter C
Access level: 2
Can be changed: C(2), U, T
Unit group: -
Min
0.000 [µF]
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
