Parameter Function Adjustment range
p1243 Vdc_max_controller dynamic factor 10 ... 200 %
Factory setting: 100 %
Setting for the dynamic factor of the vdc-max controller.
100% means that the following parameters are used in accordance with their initial settings. The use is based on a theoretical
controller optimization.
● p1250, gain
● p1251, settling time
● p1252, derivative-action time
If subsequent optimization is required, this can be set using the dynamic factor. In this case p1250, p1251, p1252 parameters
are weighted with the dynamic factor p1243.
Parameter Function Adjustment range
p1250 Vdc_controller proportional gain 0.00 ... 10.00
Factory setting: 1.00
Display of the switch-on level of the vdc-max controller.
Parameter Function Adjustment range
p1251 Vdc_controller integral time 1 ... 1000 ms
Factory setting: 40 ms
Setting for the integral-action time of the vdc controller.
The effective integral time can be determined using p1243.
Parameter Function Adjustment range
p1252 Vdc_controller derivative-action time 1 ... 1000 ms
Factory setting: 1 ms
Setting for the derivative-action time of the vdc controller.
The active derivative-action time can be determined using p1243.
Parameter Function Adjustment range
p1254 Vdc_max_controller automatic ON level detection 1 / 0
Factory setting: 0
Activates/deactivates automatic sensing of the switch-on level for the Vdc-max controller.
Values:
0: Automatic detection disabled.
1: Automatic acquisition enabled
Settings
Parameter p1240 functions as a release:
● 0: Controller inhibited
● 1: Controller enabled
