5.4.3 Code F2 (soft stop time)
When the stopping time is set to 0, it is a free stop. Too long
stopping time will bring instability to the system.

5.4.4 Code F5 (Starting limit current)
When using this function, code F9 must be set to 0 or 2 or
4, and the starting current of the starter will run below the
set value (50%- -500%). After starting, the current will drop
below the rated value. The larger the set value, the shorter
the starting time. Note that this value cannot be set too
small. If it is too small, a "Tool long starting time" fault will
occur. (Figure 5.4.4)

5.4.5 Code F6 (load regulation rate)
When the rated parameters of the soft starter selected by the user do not match the actual motor, in order to make the
protection function and display parameters correct, the load regulation rate should be reset.
Definition of load regulation
Is the actual rated current of the motor, Pr is the rated current of the soft
starter
For example:The user's motor is 200A, and the rated current of soft starter is 400A, then the set value of code F6 is
changed to 50%
5.4.6 Code F9 (starting mode)
The intelligent controller has 7 starting modes to adapt to various complicated motor and load conditions. Users can select
according to different application conditions.
Working principle
00 limited current starting mode:
When the setting item F9 is 0, set the starting mode to this mode.
Fig. 5.4.4 shows the change waveform of the electrical current in the current limiting starting mode. Where |1 is the set
starting current limit value. When the motor starts, the output voltage increases rapidly until the motor current reaches the
set current limit value|1, and the motor current is not greater than this value, and then as the output voltage gradually
increases, the motor gradually accelerates. When the motor reaches the rated speed, the output current quickly drops to
