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.

b2-04
DC Injection Braking Time
at Stop
Sets DC Injection Braking time at stop.
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. Disabled when set to
0.00.
