P1233[3] Duration of DC braking Min: 0.00
CStat: CUT Datatype: Float Unit: s Def: 0.00
P-Group: FUNC Active: Immediately QuickComm.: No Max: 250.00
Defines duration for which DC injection braking is to be active following an OFF1 or OFF3 command. When
an OFF1 or OFF3 command is received by the drive, the output frequency starts to ramp to 0 Hz. When the
output frequency reaches the value set in P1234, the drive injects a DC braking current P1232 for the time
duration set in P1233.
