Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Notice: If the activation level of the Vdc_max controller is already exceeded in the deactivated state (pulse inhibit) by the DC
link voltage, then the controller can be automatically deactivated (see F07401), so that the drive is not accelerated
the next time that it is activated.
Note: The Vdc_max controller is not switched back off until the DC link voltage falls below the threshold 0.95 * r1242 and
the controller output is zero.
Description: Sets the dynamic factor for the DC link voltage controller (Vdc_max controller).
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 p1243.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1246[V] = p1245[%] * sqrt(2) * p0210
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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.
