filtering time, the stronger the anti-interference ability, but the reaction speed becomes slower; the shorter the filtering
time, the weaker the anti-interference ability, but the reaction speed becomes faster.

PUL cutoff frequency:

This parameter defines the minimum recognition pulse frequency of the PUL port. Below the pulse frequency of this
parameter, the inverter no longer recognizes it and processes it according to the "0Hz" frequency value. The smaller the
value is set, the lower the pulse frequency that the PUL port can receive. However, when the PUL port pulse frequency
disappears, the inverter determines that the pulse input is "0 Hz" for a longer period of time.

Terminal UP/DW control mode:

0: Power-down shutdown storage When the terminal UP/DW is adjusted, the frequency record is maintained
after the machine is powered off or stopped. During power-on operation, the inverter performs UP/DW adjustment
operation from the frequency at the last stop.
1: Don't save when unelectrified and save when stopping When the terminal UP/DW is adjusted, the
frequency record is maintained after the machine stops. During the next run, the inverter performs UP/DW adjustment
operation from the frequency at the last stop. Recording is not saved after power failure, starting from 0.00Hz.
2: Valid when running and clear when stopping When the terminal UP/DW is adjusted, the frequency record is
not maintained after the machine stops or powers off. During the next run, the inverter performs UP/DW regulation
operation from a frequency of 0.00 Hz.
Terminal UP/DW controls the frequency increase and decrease rate:
This function defines the rate of change of a given frequency when the terminal UP/DW is adjusted.
F02.37 Timer time unit Setting range: 0～2
F02.38 Timer setting value Setting range: 0～65000
Timer time unit:
This function is used to set the timing unit of the inverter timer.
0: Second The timer is timed in seconds.
1: Minute The timer is timed in minutes.
2: Hour The timer is timed in hours.

Timer setting:

This parameter is used to set the timing of the inverter. The timer starts counting when the external trigger terminal
receives the valid signal, and after the timing time arrives, the pulse signal with a width of 1 second is output from the
corresponding output terminal.

The trigger terminal is determined by the multi-function input terminal selection "40: Timer Trigger Terminal". See
[F02.00~F02.12] for details.
The output terminal is determined by the multi-function output terminal selecting "21: Timer time to". See
[F02.43~F02.50] for details.
When the trigger terminal is invalid, the timer keeps the existing timing value, and the accumulated timing continues
after the trigger terminal is valid.
The timer clear terminal can clear the timing value at any time.
Tip: The timer can work independently, not limited by the running status of the inverter. When some working
conditions require timing, the inverter can be used.The timer, in which the timing time can be displayed in
[C00.30], the time unit is determined by [F02.37].

F02.40 Counter setting value Setting range: 0～65000
F02.41 Reserved
This parameter specifies the counting action of the internal counter and counts the clock type signal of the counter input
terminal.

Counter maximum:

When the count value reaches the value specified by parameter [F02.39], the corresponding output terminal outputs
a valid signal. The output signal width is equal to the clock period of the valid signal of the external input terminal, that is,
when the next count signal is input, the output terminal stops outputting the valid signal.
The input terminal is determined by the multi-function input terminal selection "42: Counter input terminal". See
[F02.00~F02.12] for details.
The output terminal is determined by the multi-function output terminal selecting "22: Counter reaches maximum
value". See [F02.43~F02.50] for details.
Counter setting:
When the count value reaches the value specified by the parameter [F02.40], the valid signal is output at the
corresponding output terminal, and the output signal width is the value of the count value exceeding the value specified
by the parameter [F02.39], causing the output terminal to be cleared when the counter is cleared. The output of the
valid signal is stopped.
The input terminal is determined by the multi-function input terminal selection "42: Counter input terminal". See
[F02.00~F02.12] for details.
The output terminal is determined by the multi-function output terminal selecting "23: Counter reaches the set value".
See [F02.43~F02.50] for details.
The count value of the counter can be cleared at any time by the counter clear terminal set by the multi-function input
terminal [F02.00~2.09].
