Goodrive3000 series medium voltage VFD
The curvature of S curve is determined by the ACC range, ACC/DEC time, starting time, and ending time.
Function
code
P01.08
0: Decelerate to stop. When a stop command takes effect, the VFD lowers output frequency based on the DEC mode and
the defined DEC time; when the frequency drops to 0Hz, the VFD stops.
1: Coast to stop. After a stop command takes effect, the VFD stops output immediately; and the load coasts to stop
according to mechanical inertia.

Starting frequency of braking for stop: During the deceleration to stop, the VFD starts DC braking for stop when running
frequency reaches the starting frequency determined by P01.09.
Wait time before braking: The VFD blocks the output before starting DC braking. After this wait time, DC braking is started
so as to prevent overcurrent caused by DC braking at high speed.
DC braking current for stop: It indicates the applied DC braking energy. Stronger current indicates greater DC braking
effect.
DC braking time for stop: It indicates the hold time of DC braking. If the time is 0, DC braking is invalid, and the VFD
decelerates to stop within the specified time.
