2.2 List of parameters
Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
AC/AC device: r1246[V] = p1245[%] * sqrt(2) * p0210
DC/AC device: r1246[V] = p1245[%] * p0210
Dependency: Refer to: p0210
Warning: An excessively high value possibly negatively influences normal drive operation, and can mean that after the line
supply returns, the Vdc minimum control can no longer be exited.
The values up to 150 % are intended for operating modes p1240 = 5, 6.
Note: For SINAMICS GM/SM, the following applies:
Minimum value = 0.75
Maximum value = 0.90
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 * p1246 and
the controller output is zero.
Description: Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
100% means that p1250, p1251, and p1252 (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 p1250, p1251,
p1252 are weighted with the dynamic factor p1247.
If several components 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 component involved.
