(4) Parameters: P073=10 P075=1 P072=40 P074=0 P076=0
[Description] This curve is an extended one of the above curve. 2V-10V (4.8mA-20mA)
is corresponding to 0Hz-40Hz and signals of 0V-2V (4-4.8mA) are invalid. The curve
can be used to avoid noise disturbance. Under severe environment, signals under 1V
shall not be used as far as possible to set operating frequency of the inverter.

0: Not memorized
1: Memorized
This parameter can be used to select whether the value modified through UP and DOWN is
memorized or not after stop. When P077 is set as 1, the value upon stop will be memorized
after re-startup; when P077 is set as 0 or the inverter is restarted after power failure, the
value modified through UP and DOWN as well as the value whose frequency is set as P003
will not be memorized.

0: For 0.01HZ, minimum up/down speed is 0.01HZ
1: For 0.1HZ, minimum up/down speed is 0.1HZ
This parameter can be used to adjust up/down speed unit for UP and DOWN to meet users'
need.

The actual increment of UP and DOWN refers to the result after values of P078 and P079 are
multiplied.
