Run Selection Used to set the operation mode by switch-
ing to the Remote mode using the
LOCAL/REMOTE key.
0: Run signals that are input during
mode switching are disregarded.
(Input Run signals after switching the
mode.)
1: Run signals become effective imme-
diately after switching to the Remote
mode.

DC Injection
Braking Start Fre-
quency Sets the frequency at which DC injection
braking starts when decelerate to stop
(b1-03 = 0) is selected. If b2-01< E1-09,
DC Injection braking starts at E1-09.
Note: Zero Speed restrictions are active
in Flux Vector Mode.

DC Injection
Braking Current Sets the DC injection braking current as a
percentage of the MxC rated current.
Note: The DC excitation current is deter-
mined by the setting in E2-03 when
operating in Flux Loop Vector
Control Method.

Braking Time at
Stop Sets the time length of DC injection brak-
ing at stop in units of 0.01 seconds.
1: When b1-03 = 2, actual DC Injection
time is calculated as follows: (b2-04)
× 10 × (OutputFreq) / (E1-04)
2: When b1-03 = 0, this parameter deter-
mines the amount of time DC Injec-
tion is applied to the motor at the end
of the decel ramp.
3: This should be set to a minimum of
0.50 seconds when using HSB. This
will activate DC injection during the
final portion of HSB and help ensure
that the motor stops completely.
