DC brake at start s generally used when the motor is restarted after it stops
completely.
If the start mode is direct start, the driver firstly performs DC brake in
accordance with the DC brake current at start, and then start running after the
setup DC brake time at start. If the DC brake time is set to 0, the driver
directly starts without passing through the DC brake.
The higher the DC brake current is, the higher the brake force is.
DC brake current at start refers to the percentage of rated current of the
driver.

S-curve speed-up/speed-down
It is used to select the frequency change mode during the driver start and
stop process.
0: Straight speed-up/speed-down
The output frequency increases or decreases along the straight line. The
speed-up/speed-down time varies with the setup speed-up/speed-down time.
IS300 series driver provides four types of speed-up/speed-down time. It can
select speed-up/speed-down time via the multifunctional digital input
terminals (F4-00 to F4-08).
1: S-curve speed-up/speed-down
The output frequency increases or decreases along the S curve. S curve is
generally used in the applications where start and stop processes are
relatively flat, such as elevator and conveyor belt. Refer to F6-08 and F6-09
for the meanings of the parameters.
