Vdc controller rate time / Vdc_ctrl t_rate
Access level: 3
Calculated: -
Data type: FloatingPoint32
Can be changed: T, U
Scaling: -
Dynamic index: DDS, p0180
Unit group: -

Function diagram: 6220
Min:
0 [ms]
Max:
1000 [ms]
Factory setting:
0 [ms]
Description:
Sets the rate time constant for the DC link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency:
The effective rate time is obtained taking into account p1243 (Vdc_max controller dynamic factor).

Description:
Sets the time threshold for the Vdc_min controller (kinetic buffering).
If this value is exceeded a fault is output; the required response can be parameterized.
Prerequisite: p1256 = 1
Dependency:
See also: F07406
NOTICE
If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1240 = 3) so that the
drive does not shut down with overvoltage when Vdc_min control is exited (due to the time violation) and in the event
of fault response OFF3. It is also possible to increase the OFF3 ramp-down time p1135.
