performs DC braking at the set startup DC braking current. After the startup DC braking
time, the AC drive starts to run. If the startup DC braking time is 0, the AC drive starts
directly without DC braking. The larger the startup DC braking current is, the larger the
braking force is.

on the set pre-excited current. After the pre-excited time, the AC drive starts to run. If the
pre-excited time is 0, the AC drive starts directly without pre-excitation.
The startup DC braking current or pre-excited current is a percentage relative to the base
value.
 If the rated motor current is less than or equal to 80% of the rated AC drive current, the
base value is the rated motor current.
 If the rated motor current is greater than 80% of the rated AC drive current, the base
value is 80% of the rated AC drive current.
