b2: DC Injection Braking
b2 parameters
set the DC Injection Braking functions.
•
DC Injection Braking: A braking method that injects DC current into the motor windings. This function should not
be used too frequently, because it generates a fair amount of heat in the motor.

b2-01
(0189)
DC Injection/Zero
SpeedThreshold
Sets the frequency to start DC Injection Braking.
0.5 Hz
(0.0 - 10.0 Hz)
Note:
This parameter is available when
b1-03 = 0 [Stopping Method Selection = Ramp to Stop]
.
Function of b2-01
b2-01
sets the frequency to start DC Injection Braking at stop. When the output frequency is less than or equal to the value set in
b2-01
, the drive will inject the quantity of DC current
set in
b2-02 [DC Injection Braking Current]
into the motor for the time set in
b2-04 [DC Inject Braking Time at Stop]
.

Note:
When
b2-01 ≤ E1-09 [Minimum Output Frequency]
, the drive will start DC Injection Braking from the frequency set in
E1-09
.
