b2: DC Injection Braking
Use b2 parameters to configure DC Injection Braking operation
b2-01
DC Injection Braking
Start Frequency
Sets the frequency at which DC Injection
Braking starts when Ramp to Stop (b1-03 = 0)
is selected. If b2-01< E1-09, DC Injection
Braking starts at E1-09.

DC Injection Braking
Time/DC Excitation
Time at Start
Sets the time of DC Injection Braking at start in
units of 0.01 seconds. Disabled when set to 0.00
seconds.
Used to stop a coasting motor.

DC Injection Braking
Time at Stop
Sets the time length of DC Injection Braking at
stop in units of 0.01 seconds.
When b1-03 = 2, actual DC Injection time is
calculated as follows:
(b2-04) x 10 x (Output Freq) / (E1-04).
When b1-03 = 0, this parameter sets the amount
of DC Injection time applied to the motor at the
end of the decel ramp.
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.
Disabled when set to 0.00.
