BI: Enable DC braking
0:0 - 4000:0
0:0
--
Enable DC braking via a signal applied from an external source. Function remains active while external input
signal is active.
DC braking causes the motor to stop rapidly by applying a DC braking current (current applied also holds
shaft stationary).
When the DC braking signal is applied, the inverter output pulses are blocked and the DC current is not applied
until the motor has been sufficiently demagnetized.
Possible settings:
722.0
Digital input 1 (requires P0701 to be set to 99, BICO)
722.1
Digital input 2 (requires P0702 to be set to 99, BICO)
722.3
Digital input 3 (requires P0703 to be set to 99, BICO)
Cautions:
With the DC braking, the kinetic energy of the motor is converted into heat in the motor. The drive could
overheat if it remains at this status for an exessive time period.
DC braking is not possible when using a synchronous motor.
P1232
DC braking current
0 - 250
100
%
Defines level of DC current in [%] relative to rated motor current (P0305).
P1233
Duration of DC braking
0 - 250
0
s
Defines duration for which DC injection braking is to be active following and OFF1 or OFF3 command.
Setting this parameter between 0.01 and 250.00 sets the time duration (in seconds) of the DC injection starting
with the OFF1 or OFF3 command.
