2.2 b: Application
DC Injection Braking time is determined by the value set to b2-04 and by the output frequency at the time the Stop
command is input or the Run command is removed. It can be calculated by:
Figure 2.3
Note: If an overcurrent (OC) fault occurs during DC Injection Braking to Stop, lengthen the minimum baseblock time (L2-03) until the
fault no longer occurs.
Setting 3: Coast to Stop with Timer
When a Stop command is input or the Run command is removed, the drive will turn off its output and the motor will
coast to a 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.
Figure 2.4
The wait time t is determined by the output frequency when the Stop command is input or the Run command is removed
and by the active deceleration time.
