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 (Used for Back Spin Control on Vertical Turbine Pumps)
When the Run command is removed, the drive coasts to a stop. If parameter b1-11 = 0, the coast-timer (Run Delay at Stop)
becomes a value determined by a combination of output frequency and C1-02. However, if b1-11 > 0, the Run Delay at Stop
timer is set to b1-11. If the Run command is reissued during the Run Delay at Stop timer time, the drive WILL restart when
the timer expires without the need to re-cycle the Run command. The Run Delay at Stop timer will operate for both AUTO
Mode and HAND Mode. The Run Delay at Stop timer will still operate when the drive goes to sleep and then wakes up. During
the Run Delay at Stop timer execution, the HOA keypad will display a Start Delay message.

b1-04: Reverse Operation Selection
For some applications, reverse motor rotation is not appropriate and may even cause problems (e.g., air handling units, pumps,
etc.). Setting parameter b1-04 to 1 instructs the drive to ignore any Reverse run commands.
