Description
Output frequency f
fmax
t1
Note: If mode 1 is selected, set P01.06, P01.07,
P01.27, and P01.28 accordingly.
The curvature of S curve is determined by the
ACC range and ACC/DEC time.
Output frequency f
t1 t2 t3
Setting range: 0.0–50.0s
0: Decelerate to stop. After a stop command
takes effect, the VFD lowers output frequency
based on the DEC mode and the defined DEC
time; after the frequency drops to the stop speed
(P01.15), 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 DC 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 DC 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.
