List Manual, 09/2017, A5E33842890
Description:
Sets the integral time for the DC link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency:
The effective integral time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note:
p1251 = 0: The integral component is deactivated.
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).
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description:
Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller.
Value:
0:
Automatic detection inhibited
1:
Automatic detection enabled
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: 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.
