b2: DC Injection Braking

b1-07

Local/Remote
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.

b2-01

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.

b2-04

DC Injection
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.
