decreases in S curve;
S curve is generally used in cases where smooth
start/stop is required, eg, elevator, conveyer belt,
etc.

Note: When set to 1, it is required to set
P01.06, P01.07, P01.27 and P01.28
accordingly.

Time of starting
section of
acceleration S
curve
The curvature of S curve is determined by
acceleration range and acceleration and
deceleration time.

Stop mode
0: Decelerate to stop; after stop command is valid,
the inverter lowers output frequency based on the
deceleration mode and the defined deceleration
time, after the frequency drops to the stop speed
(P01.15), the inverter stops.
1: Coast to stop; after stop command is valid, the
inverter stops output immediately, and the load
coasts to stop as per mechanical inertia.

Starting
frequency of DC
brake after stop
Starting frequency of DC brake after stop; during
decelerating to stop, when this frequency is
reached, DC brake will be performed after stop.
Demagnetization time (waiting time of DC brake
after stop): Before the DC brake, the inverter will
block output, and after the demagnetization time
elapses, DC brake will start. This function is used
