Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
AC/AC device: r1286[V] = p1285[%] * sqrt(2) * p0210
DC/AC device: r1286[V] = p1285[%] * p0210
Warning: An excessively high value may adversely affect normal drive operation. The values up to 150 % are intended for
operating modes p1240 = 5, 6.
Description: Displays the switch-in level for the Vdc_min controller (kinetic buffering).
Note: The Vdc_min controller is not switched back off until the DC link voltage rises above the threshold 1.05 * r1286 and
the controller output is zero.
Description: Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
100% means that p1290, p1291, and p1292 (gain, integral time, and rate time) are used corresponding to their basic
settings and based on a theoretical controller optimization.
If subsequent optimization is required, this can be carried out using the dynamic factor. In this case, p1290, p1291,
and p1292 are weighted with the dynamic factor p1287.
If several modules are connected to the DC link, then the dynamic factor must be increased corresponding to the
ratio of the additional capacitances to the capacitance of the module involved.
Note: The pre-setting of the dynamic factor is based on the power units connected to DRIVE-CLiQ. It is assumed that the
power units connected via DRIVE-CLiQ are also electrically connected to the DC link. If this is not the case, then the
dynamic factor must be optimized manually.
Description: Sets the feedback factor for the ramp-function generator.
Its ramp times are decelerated relative to the output signal of the Vdc_max controller.
