SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Parameter P0210 defines the supply voltage. Its default value depends upon the type of inverter.
If P0210 does not correspond to the supply voltage, then it must be modified (see Dependency).
Dependency: Optimizes Vdc controller, which extends the ramp-down time if regenerative energy from motor would otherwise
cause DC-link overvoltage trips.
Reducing the value enables controller to cut in earlier and reduce the risk of overvoltage.
Set P1254 ("Auto detect Vdc switch-on levels") = 0.
Cut-in levels for Vdc-controller and compound braking are then derived directly from P0210 (supply voltage).
Description: Shows the selected output filter.
Values: 0: No output filter
1: Output choke
2: du/dt-filter
3: AppropiateSiemens sinus-/LC-filter
4: Custom sinus-/LC-filter
Dependency: If a sinus-/LC-filter [P0230 = 3 or (P0230 = 4 and P0234 > 0)] is selected:
• the modulation index is limited to 100 % (P1803 = 100) what limits the output voltage.
• -the modulation type is set to SVM (P1802 = 2).
• -the resultant max. output frequency r1084 is limited depending on the filter and motor specifications.
Caution: Inverter size and motor size (nominal power) should fit together.
Do not start the drive if a LC-filter is connected and no load is present.
This could damage the filter.
Note: If a filter type is not available for the used inverter, the option is not selectable.
The paramter is only changeable in quick commissioning. In case of an internal sinus-/LC- output filter it will be set
to LC-filter (P0230 = 3) and is not visible and changeable.
Description: Indexed parameter to display maximum allowable cable length between inverter and motor.
Index: [0] = Max. allowed unscreened cable length
[1] = Max. allowed screened cable length
Notice: For full EMC compliance, the screened cable must not exceed 25 m in length when an EMC filter is fitted.
