5.00Hz means the startup frequency is 5.00Hz.
F4-04
˙
2.0s means that the startup frequency retention time is 2.0s.
In this case, the inverter directly starts at 5Hz and remains for 2 seconds,
and then accelerates to the setup frequency 10Hz.
Caution:
1)
The startup frequency and retention time is not limited by the
frequency lower limit.
2)
The retention time is not included in the acceleration time.
3)
At the time of switching between forward and reverse rotations,
the startup frequency and retention time has no action.

The DC brake at startup is generally used when the motor is restarted upon
stopping completely.
If the startup mode is direct startup, it will firstly perform DC brake with the
DC brake current at startup and then start running after the period of DC
