P1245[3] Switch on level kin. buffering Min: 65
CStat: CUT Datatype: U16 Unit: % Def: 76
P-Group: FUNC Active: Immediately QuickComm.: No Max: 115
Enter switch-on level for kinetic buffering (KIB) in [%] relative to supply voltage (P0210).

P1245[0] : 1st. Drive data set (DDS)
P1245[1] : 2nd. Drive data set (DDS)
P1245[2] : 3rd. Drive data set (DDS)
Warning:
Increasing the value too much, may interfere with the drive normal operation.
Note:
Changing P1254 does not affect the switch-on-level for KIB.
r1246[3] CO:Switch-on level kin buffering Min: -
Datatype: Float Unit: V Def: -
P-Group: FUNC Max: -
Displays switch-on level of kinetic buffering (KIB, Vdc min controller).
Depending on the setting selected, the frequency limit defined in P1245 is used to either hold the speed or
disable pulses. If not enough regeneration is produced, drive may trip undervoltage.
P1247[3] Dyn. factor of kinetic buffering Min: 10
CStat: CUT Datatype: U16 Unit: % Def: 100
P-Group: FUNC Active: Immediately QuickComm.: No Max: 200
Enters dynamic factor for kinetic buffering (KIB, Vdc-min controller).
P1247 = 100 %
means parameters P1250, P1251 and P1252 (gain, integration time and differential time) are used as set.
Otherwise, these are multiplied by P1247 (dynamic factor of Vdc-min).

P1247[1] : 2nd. Drive data set (DDS)
P1247[2] : 3rd. Drive data set (DDS)
Note:
Vdc controller adjustment is calculated automatically from motor and inverter data.
P1250[3] Gain of Vdc-controller Min: 0.00
CStat: CUT Datatype: Float Unit: - Def: 1.00
P-Group: FUNC Active: Immediately QuickComm.: No Max: 10.00
Enters gain for Vdc controller.

P1251[3] Integration time Vdc-controller Min: 0.1
CStat: CUT Datatype: Float Unit: ms Def: 40.0
P-Group: FUNC Active: Immediately QuickComm.: No Max: 1000.0
Enters integral time constant for Vdc controller.

P1252[3] Differential time Vdc-controller Min: 0.0
CStat: CUT Datatype: Float Unit: ms Def: 1.0
P-Group: FUNC Active: Immediately QuickComm.: No Max: 1000.0
Enters differential time constant for Vdc controller.
