Description: Sets the normalized integral time for the infeed current controller.
Note: A value of 100 % corresponds to the basic setting derived from loop control parameters (p3421, p3422).
Description: Displays the integral component of the active current controller.
Description: Displays the integral action component of the reactive current controller.
Description: Sets the switch-in threshold for the current controller adaptation.
The value refers to the maximum power modular current (r0209). From the starting threshold onwards, the induc-
tance value (p3421) used for current control is reduced linearly as a function of the current value. The inductance
value for the maximum power unit current is therefore p3421 * p3622.
Dependency: Refer to: p3410, p3415, p3622
Note: The parameter can be set automatically set using the line supply identification (p3410 = 4, 5) (also refer to p3622).
Prerequisite for a reliable measurement of p3622 is that the current magnitude for run 2 (p3415[1]) is at least 10 %
higher than the current magnitude for run 1 of the line supply identification. Otherwise, the measurement result is
rejected.
In the case of a correct measurement, p3620 is set to 80% of the current magnitude for run 1 (p3415[0]).
For chassis power units, it is generally not necessary to adapt p3620 and p3622 to the characteristics of the line
supply. However, when required, the current controller adaptation can be optimized by selecting suitable current
magnitudes for p3415.
For booksize power units, p3620 and p3622 are automatically adapted with the then valid default setting of the line
identification p3415.
