Parameters
List of Parameters
p1251[0...n] Vdc controller integral time / Vdc_ctrl Tn
PM230 Access level: 3
PM240
Can be changed: U, T
Min
0 [ms]
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).
Note: p1251 = 0 deactivates the integral component of the Vdc controller.
p1252[0...n] Vdc controller rate time / Vdc_ctrl t_rate
PM230 Access level: 3
PM240
Can be changed: U, T
Min
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).
p1254 Vdc_max controller automatic ON level detection / Vdc_max SenseOnLev
PM230 Access level: 3
Can be changed: U, T
Min
0
Description: Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0:

p1254 Vdc_max controller automatic ON level detection / Vdc_max SenseOnLev
PM240 Access level: 3
Can be changed: U, T
Min
0
Description: Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0:
1:
p1255[0...n] Vdc_min controller time threshold / Vdc_min t_thresh
PM240 Access level: 3
Can be changed: U, T
Min
0.000 [s]
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: 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.
