2.2 b: Application
The time for DC Injection Braking is determined by the value set in b2-04 and by the output frequency at the time the
Stop command is input or the Run command is turned OFF. It can be calculated by:
Figure 2.3
Note: If an overcurrent (oC) fault occurs during DC Injection Braking to a 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 turned OFF, the drive will turn off its output and the motor will
coast to a stop. If a Run command is input before the time t has elapsed, the drive will not start.
Figure 2.4
The wait time t is determined by the output frequency when the Stop command is input and by the active deceleration
time.
