SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the proportional gain for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective proportional gain is obtained taking into account p1243 (Vdc_max controller dynamic factor) and the
DC link capacitance of the power unit.
Description: Sets the integral time for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective integral time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note: p1251 = 0: The integral component is de-activated.
Description: Sets the rate time constant for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective rate time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0: Automatic detection inhibited
