5.2 b: Application
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:
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 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.
The wait time t is determined by the output frequency when the Run command is removed and by the active deceleration time.
n b1-04: Reverse Operation Selection
Enables and disables Reverse operation. For some applications, reverse motor rotation is not appropriate and may cause
problems (e.g., air handling units, pumps, etc.).
