2 Parameters
2.2 List of parameters
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.
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.
Description: Sets the proportional gain for the Vdc controller (DC link voltage controller).
Note: The gain factor is proportional to the capacitance of the DC link.
The parameter is pre-set to a value that is optimally adapted to the capacitance of the power unit.
Description: Sets the integral time for the Vdc controller (DC link voltage controller).
Description: Sets the rate time constant for the Vdc controller (DC link voltage controller).
