Startup DC braking is generally used during restart of the AC drive after the rotating motor
stops
.
Startup DC braking is valid only for direct start
(
P4
-

=
0
).
In this case
,
the AC drive
performs DC braking at the set startup DC braking current
.
After the startup DC braking
time
,
the AC drive starts to run
.
The larger the startup DC braking current is
,
the larger the
braking force is
.
The startup DC braking current is a percentage relative to the base value
.
If the startup DC
braking time is 0
,
the AC drive starts directly without DC braking
.
