DWELL
The DWELL function temporarily holds the frequency reference at a predefined value for a set
time then continues accelerating or decelerating.
The DWELL function helps prevent speed loss when starting and stopping a heavy load with
induction motors. When running a PM motor in V/f control, the pause in acceleration allows
the PM motor rotor to align with the stator field of the motor and reduce the starting current.
