[OFF])
①
If
and
> reference frequency
: DC injection braking
,
②
If

: Operation at command frequencies,
If
and

③
If an operation command is entered during D.C. braking : D.C. braking is discontinued to restart the
operation.
[Priority to DC injection braking during forward/reverse operation]
(Forward/reverse run D.C. braking priority control
=
(ON))
④
During normal forward/reverse run(
=
)
:
Not recognized as a stop command, so that DC injection braking is not active.
⑤
If a reverse run (or forward) command is entered during forward run (or reverse)
(
=
)
:
DC injection braking starts when the frequency set with
exceeds the
reference frequency during deceleration.
⑥
If an operation command is entered during D.C. braking
:
priority is given to D.C. braking.
