p1245[0...n] Vdc_min controller switch-in level (kinetic buffering) / Vdc_min on_level
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: REL
Min
65 [%]
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
r1246 Vdc_min controller switch-in level (kinetic buffering) / Vdc_min on_level

Data type: FloatingPoint32

Not for motor type: REL
Min
- [V]
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.
p1247[0...n] Vdc_min controller dynamic factor (kinetic buffering) / Vdc_min dyn_factor
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: REL
Min
1 [%]
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.
