performs DC injection braking at the DC injection braking 1 level. After DC injection braking
1 level, the AC drive starts to run. If the DC injection braking 1 level is 0, the AC drive starts
directly without DC injection braking. The larger the DC injection braking 1 level is, the larger
the braking force is.

based 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 DC injection braking 1 level or pre-excitation level 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.

0
It is used to set the frequency change mode during the AC drive start and stop process.
‡
0: Linear acceleration/deceleration
The output frequency increases or decreases in linear mode. The MD380 provides four
group of acceleration/deceleration time, which can be selected by using F4-00 to F4-08.
‡
1: S-curve acceleration/deceleration A
The output frequency increases or decreases along the S curve. This mode is generally
used in the applications where start and stop processes are relatively smooth, such as
