Parameters
List of Parameters
p1250[0...n] Vdc controller proportional gain / Vdc_ctrl Kp
PM230 Access level: 3
PM240
Can be changed: U, T
Units group: -
Min
0.00
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.
p1251[0...n] Vdc controller integral time / Vdc_ctrl Tn
PM230 Access level: 3
PM240
Can be changed: U, T
Units group: -
Min
0 [ms]
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.
p1252[0...n] Vdc controller rate time / Vdc_ctrl t_rate
PM230 Access level: 3
PM240
Can be changed: U, T
Units group: -
Min
0 [ms]
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).
p1254 Vdc_max controller automatic ON level detection / Vdc_max SenseOnLev
PM230 Access level: 3
Can be changed: U, T
Units group: -
Min
0
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0:
