B6: Dwell Function - YASKAWA FSDrive-MV1000 Parameter Manual

◆ b6: Dwell Function

The Dwell function is used to temporarily hold the frequency reference at a predefined value for a set time, then continue
accelerating or decelerating.
The Dwell function can help prevent speed loss when starting and stopping a heavy load.
The figure below shows how the Dwell function works.
Note: Using the Dwell function requires that the stopping method for the drive be set to "Ramp to stop" (b1-03 = 0).
