0: Inhib Vdc ctrl
1: Enables Vdc_max controller
2: Enables Vdc_min controller (kinetic buffering)
3: Enables Vdc_min controller and Vdc_max controller
4: Activates Vdc_max monitoring
5: Activates Vdc_min monitoring
6: Activates Vdc_min monitoring and Vdc_max monitoring
<2> The Vdc controller is switched on when reaching the threshold value. The switch-off hysteresis is 5% of the switch-on level.
<3> As standard, the controller is designed as a P controller.
