Vdc_Max Controller Dynamic Factor (U/F) / Vdc_Max Dyn_Factor; Vdc_Max Controller Time Threshold (U/F) / Vdc_Max T_Thresh; Vdc_Min Controller Switch-In Level (Kinetic Buffering) (U/F) - Siemens SINAMICS G150 Manual

Vdc_max controller dynamic factor (U/f) / Vdc_max dyn_factor

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
1 [%]
Description: Sets the dynamic factor for the DC link voltage controller (Vdc_max controller).
100% means that p1290, p1291, and p1292 (gain, integral time, and rate time) are used in accordance with their
basic settings and on the basis of 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 p1283.
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.
p1284[0...n]

Vdc_max controller time threshold (U/f) / Vdc_max t_thresh

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
0.000 [s]
Description: Sets the monitoring time for the Vdc_max controller.
If the down ramp of the speed setpoint is held for longer than the time set in p1284, then fault F07404 is output.
p1285[0...n] Vdc_min controller switch-in level (kinetic buffering) (U/f) / Vdc_min on_level
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
65 [%]
Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
AC/AC unit: p1286[V] = p1285[%] * sqrt(2) * p0210
DC/AC unit: p1286[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.
r1286 Vdc_min controller switch-in level (kinetic buffering) (U/f) / Vdc_min on_level
VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
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 * p1286 and
the controller output is zero.
