List Manual, 09/2017, A5E33842890
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.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description:
Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1286[V] = p1285[%] * sqrt(2) * p0210
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Warning:
An excessively high value may adversely affect normal drive operation.
Description:
Displays the switch-in level for the Vdc_min controller (kinetic buffering).
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
The Vdc_min controller is not switched back off until the DC link voltage rises above the threshold 1.05 * r1286 and
the controller output is zero.
Description:
Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
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, this can be carried out using the dynamic factor. In this case, p1290, p1291,
and p1292 are weighted with the dynamic factor p1287.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
