Index:
P1233[0] : 1st. Drive data set (DDS)
P1233[1] : 2nd. Drive data set (DDS)
P1233[2] : 3rd. Drive data set (DDS)
Value:
P1233 = 0.00 :
Not active following OFF1 / OFF3.
P1233 = 0.01 - 250.00 :
Active for the specified duration.
Caution:
With the DC braking, the kinetic energy of the motor is converted into heat in the motor. The drive could
overheat if the remains in this status for an exessive period of time !
DC braking is not possible when using a synchronous motor (i.e. P0300 = 2).
Notice:
The DC braking function causes the motor to stop rapidly by applying a DC braking current (the current
applied also holds the shaft stationary). When the DC braking signal is applied, the inverter output pulses
are blocked and the DC current not applied until the motor has been sufficiently demagnetized.
Demagnetization time is calculated automatically from motor data.
The inverter will not restart if an ON-command is given during this period.
P1234[3] DC braking start frequency Min: 0.00
CStat: CUT Datatype: Float Unit: Hz Def: 650.00
P-Group: FUNC Active: Immediately QuickComm.: No Max: 650.00
Sets start frequency for DC braking.
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 start frequency of DC braking P1234, the drive injects a
DC braking current P1232 for the time duration set in P1233.
