Note: p3555[0]:
Vdc system deviation as a percentage of the setpoint of the DC link voltage (first condition to initiate fast controller
intervention). The threshold is also used to internally change over the modulation depth calculation for high system
deviations and should therefore generally not be changed!
p3555[1]:
Vdc threshold as a percentage of the rectified value of the actual line supply voltage (second condition to initiate the
fast controller intervention). Both threshold conditions must be fulfilled to initiate the controller intervention.
p3555[2]:
Percentage overall level of the fast intervention (scaling factor). For a line supply identification with p3410 >= 2, the
factor is automatically adapted or, for weak line supplies with a high inductance, set to 0.
p3555[3]:
Percentage correction of the pre-control for a fast voltage dip (dead time compensation).
p3555[4]:
Percentage minimum time between controller interventions (100% corresponds to 100 ms). If high load change fre-
quencies occur with the application, the minimum time between two controller intervention can be reduced using
p3555[4].
p3555[5]:
Percentage overall level of the fast intervention (scaling factor). With p3555[5] = 0, the fast controller intervention is
inhibited. For weak line supplies with a high inductance, it makes sense to de-activate the fast intervention.
Description: Sets the normalized proportional gain for the DC link voltage controller (Vdc controller).
Note: A value of 100 % corresponds to the basic setting derived from loop control parameters (p3421, p3422).
Description: Sets the normalized integral time for the DC-link voltage controller (Vdc).
Note: A value of 100 % corresponds to the basic setting derived from loop control parameters (p3421, p3422).
Description: Sets the filter time constant for the DC link voltage monitor (Vdc).
