2.2 List of parameters
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.
Description: Sets the lower speed threshold for the Vdc_max controller.
When this speed threshold is undershot, the Vdc_max control is switched out and the speed is controlled using the
ramp-function generator.
Note: For fast braking where the ramp-function generator tracking was active, it is possible to prevent the drive rotating in
the opposite direction by increasing the speed threshold and setting a final rounding-off time in the ramp-function
generator (p1131). This is supported using a dynamic setting of the speed controller.
Description: Sets the proportional gain for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective proportional gain is obtained taking into account p1243 (Vdc_max controller dynamic factor).
