through the multifunction digital input terminals (P5 Group).
1: S curve mode
The output frequency is increasing or decreasing by following S curve. Normally S curve
mode is used in applications which require relatively smooth and gentle start and stop, such as
elevators, belt conveyor. For its parameter definitions, refer to P1.06 and P1.07.

The t1 in following figure is the time defined by P1.06, within which the output frequency is
changed in a gradually increased slope. The t2 is the time defined by P1.07. Within the period
between t1 and t2, the frequency changing slope is constant. The curvature of S curve is
codetermined by the Acceleration range, the Acceleration/Deceleration time, beginning stage
time and the ending stage time.

0: Deceleration stop
After the stop command is enabled, the inverter decreases the output frequency
according to the Deceleration mode and the defined Acceleration /Deceleration time, and the
motor is stopped when the frequency is 0.
1
Free-run stop
Once the stop command is valid, the inverter immediately ends the output. The loading is
freely stopped by its mechanical inertia.
