Switch On Level Kin. Buffering; Co:switch-On Level Kin Buffering; Dyn. Factor Of Kinetic Buffering; Gain Of Vdc-Controller - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P1245[3]

Switch on level kin. buffering

CStat: CUT
P-Group: FUNC
Enter switch-on level for kinetic buffering (KIB) in [%] relative to supply voltage (P0210).
P1245 [V] =
Index:
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

P-Group: FUNC
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

CStat: CUT
P-Group: FUNC
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).
Index:
P1247[0] : 1st. Drive data set (DDS)
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

CStat: CUT
P-Group: FUNC
Enters gain for Vdc controller.
Index:
P1250[0] : 1st. Drive data set (DDS)
P1250[1] : 2nd. Drive data set (DDS)
P1250[2] : 3rd. Drive data set (DDS)
P1251[3] Integration time Vdc-controller
CStat: CUT
P-Group: FUNC
Enters integral time constant for Vdc controller.
Index:
P1251[0] : 1st. Drive data set (DDS)
P1251[1] : 2nd. Drive data set (DDS)
P1251[2] : 3rd. Drive data set (DDS)
P1252[3] Differential time Vdc-controller
CStat: CUT
P-Group: FUNC
Enters differential time constant for Vdc controller.
Index:
P1252[0] : 1st. Drive data set (DDS)
P1252[1] : 2nd. Drive data set (DDS)
P1252[2] : 3rd. Drive data set (DDS)
