5.2 b: Application
The time for DC Injection Braking is determined by the value set to b2-04 and by the output frequency at the time the Run
command is removed. It can be calculated by:
Figure 5.7 DC Injection Braking Time Depending on Output Frequency
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 the Run command is removed, the drive will turn off its output and the motor will coast to stop. If a Run command
is input before the operation wait time t expires, the drive will not rotate the motor and the Run command will need to be
cycled before operation can occur.
Run Command
Output Frequency
The operation wait time t is determined by the output frequency when the Run command is removed and by the active
deceleration time.
