b6: Dwell Function
The reference hold or Dwell function is used to temporarily hold the output frequency at a set reference value, for a set
time, and then continue to ramp up or stop.
The Dwell at start function can be used when driving a permanent magnet motor in V/f Control, or a motor with a heavy
starting load. The pause in acceleration allows the
PM motor rotor to align with the stator field of the motor, thus reducing
the starting current.
Dwell works as shown in the figure below.
Note: Using the Dwell function requires that the stopping method for the drive be set to “Ramp to Stop” (b1-03 = 0).
