The above function codes define the input ranges of analog input voltage channels AI1 and AI2 and their
corresponding physical quantity percentages and filtering time constants. Among them, AI2 can be selected as
voltage/current input through J1 jumper, and its digital setting can be set according to the relationship between 0 ~ 20mA
and 0 ~ 10v. The specific setting should be based on the actual situation of the input signal.
The input filtering time constants of AI1 and AI2 are mainly used for filtering processing of analog input signals to
eliminate the influence of interference. The larger the time constant, the stronger the anti-interference ability, the more
stable the control, but the slower the response; On the contrary, the smaller the time constant, the faster the response, but
the weaker the anti-interference ability, and the control may be unstable. If the optimal value cannot be determined in
practical application, the value of this parameter should be appropriately adjusted according to whether the control is stable
or not and the situation of response delay.

When the analog input signal fluctuates frequently near a given value, the frequency fluctuation caused by this
fluctuation can be suppressed by setting 06.12.

When 00.15=1 (high frequency mode), the maximum value of this function code is 500.0Hz.

These two function codes are used to set the zero frequency return control function. Take the analog AI1 current given
channel as an example, as shown in Figure F6-1.
Starting process:
After the running command is issued, only when the analog AI1 current input reaches or exceeds a certain value Ib
and its corresponding stated frequency reaches fb, the motor starts to start and accelerates to the frequency corresponding
to the simulated AI1 current input according to the acceleration time.
Shutdown process:
In the process of running, when the current value of AI1 is reduced to Ib, the inverter will not stop immediately, and
only when the current of AI1 continues to decrease to Ia and the corresponding stated frequency is fa, will the inverter stop
outputting. Here, fb is defined as zero frequency operation threshold, which is defined by 06.13, and the value of fb-fa is
defined as zero frequency return difference, which is defined by function code 06.14.
With this function, the sleep function can be completed, the energy-saving running can be realized, and the inverter
can be prevented from starting frequently at the threshold frequency through the width of the return difference.
