Note: After a stop is initiated, any subsequent Run command entered will be ignored until the minimum baseblock time (L2-03) has expired. Do
not enter Run command until it has come to a complete stop. Use DC Injection at Start (Refer to b2: DC Injection Braking and Short
Circuit Braking on page 284) or Speed Search (Refer to b3: Speed Search on page 285) to restart the motor before it has completely
stopped.
Setting 2: DC Injection Braking to Stop
When the Run command is removed, the drive will enter baseblock (turn off its output) for the minimum baseblock time
(L2-03). When the minimum baseblock time has expired, the drive will inject the amount DC current set in parameter b2-02
into the motor windings to brake the motor. The stopping time in DC Injection Braking to Stop is significantly faster compared
to Coast to Stop.
Note: This function is not available in OLV/PM control mode (A1-02 = 5).

DC Injection Braking time is determined by the value set to b2-04 and the output frequency at the time the Run command is
removed. It can be calculated by:
DC Injection brake time
(b2-04) x 10 x Output frequency
