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

Note: If an overcurrent (oC) fault occurs during DC Injection Braking to Stop, increase the momentary power loss minimum baseblock time
(L2-03) until the fault no longer occurs.
Setting 3: Coast with Timer
When the Run command is removed, the drive will turn off its output and the motor will coast to stop. The drive will not start
if a Run command is input before the time t (C1-02) has expired. Cycle the Run command that was activated during time t
after t has expired to start the drive.
