SINAMICS S List Manual (LH1), 07/2007
Description:
Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
AC/AC device: p1245[V] = p1245[%] * sqrt(2) * p0210
DC/AC device: p1245[V] = p1245[%] * p0210
Dependency:
Refer to: p0210
Warning:
An excessively large value may adversely influence normal drive operation. 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).
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, then this can be realized using the dynamic factor. In this case p1250,
p1251, p1252 are weighted with the dynamic factor p1247.
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 at DRIVE-CLiQ. It is assumed that the
power unit, connected via DRIVE-CLiQ is also electrically connected to the DC link. If this is not the case, then the
dynamic factor must be optimized manually.
