Note:
p1240 = 4, 5, 6:
When the threshold in r1282 or r1286 is reached, the DC link voltage monitoring initiates a fault (F07403 or F07404)
with a response and therefore reduces additional negative effects on the DC link voltage.
Description:
Displays the switch-in level for the Vdc_max controller.
If p1294 = 0 (automatic sensing of the switch-in level = off), then the following applies:
AC/AC device: r1282 = 1.15 * sqrt(2) * V_mains = 1.15 * sqrt(2) * p0210 (supply voltage)
DC/AC device: r1282 = 1.15 * Vdc = 1.15 * p0210 (supply voltage)
If p1294 = 1 (automatic sensing of the switch-in level = on), then the following applies:
r1282 = Vdc_max - 50.0 V (Vdc_max: Overvoltage threshold of the power unit)
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 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 p1290,
p1291, 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 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.
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 large value may adversely influence normal drive operation. The values up to 150 % are intended
for operating modes p1240 = 5, 6.
