When the setting item F9 is 4, set the starting mode to this mode. Fig. 5.4.6c is the output current waveform of the current
ramp start mode, where 11 is the current limit value set by F5, and T1 is the time value set by F1.
The current ramp starting mode has a strong acceleration capability, which is suitable for two-pole motors and can also
shorten the starting time within a certain range.

05 Double closed loop starting mode of voltage current limit:
When the setting item F9 is 5, set the starting mode to this mode.
Double closed loop starting mode of voltage current limit
uses voltage ramp and current-limiting double closed-loop
control. It is a comprehensive starting mode that requires both stable starting and strict current limiting. It uses a predictive
algorithm for estimating the working state of the motor.
The output voltage waveform of this starting mode will vary according to the motor and load conditions.
06 Monitor starting mode:
Starting in this mode, it will run in direct starting mode. It can monitor the parameters such as the motor running current.
When the operation is overloaded, over-voltage or under-voltage, the fault output 5 and 6 terminals are disconnected from
the output, and the corresponding fault information is displayed at the same time.
5.4.7 Code FA (protection level)
In order to adapt to different applications, the protector has five protection levels, namely 00: primary, 01: light load, 02:
standard, 03: heavy load, 04: advanced, which are set by the setting item FA. among them:
·The primary protection only retains the overheating, short circuit and input phase loss protection during starting, which is
suitable for occasions requiring unconditional emergency starting.
·The three protection levels such as light load, standard and heavy load have complete protection functions. The
difference is that the protection time curve of motor overload is different. The motor thermal protection time parameters are
shown in Table 5.4.7 and Fig.5.4.7.
·The protection standard of advanced protection is stricter when starting, and other protection function parameters are the
same as the standard protection setting time.
