2: MAX (master and auxiliary) take the largest absolute value in frequency source
master setting and frequency source auxiliary setting as command frequency.
3: MIN (master and auxiliary) take the smallest absolute value in frequency source
master setting and frequency source auxiliary setting as command frequency. In addition,
when the arithmetic result of master and auxiliary is selected as frequency source, you can set
offset frequency by F0.08 and overlay offset frequency to the arithmetic result of master and
auxiliary, so as to respond flexibly to various needs.
4: frequency source master setting X frequency source auxiliary setting and divided by
the maximum value of frequency as the frequency command.
Frequency source
F0.08
offset frequency when
superimposing
The function code is only valid when the arithmetic result of master and auxiliary is
selected as frequency source.
When the arithmetic result of master and auxiliary is selected as frequency source, F0.08
is used as offset frequency, and it overlays with the arithmetic result of master and auxiliary
as the set value of final frequency so that the frequency setting can be more flexible.

selection for digital set
frequency
This feature is only frequency source for the digital set.
"W/O memory" refers to that the digital set frequency value will recovered to F0.01
(preset frequency) value when the inverter stops, and the frequency correction by the ▲/▼
key on the keyboard or terminals UP, DOWN is cleared.
"W/ memory" refers to that the digital set frequency is reserved when the inverter stops,
and the frequency correction by the ▲/▼ key on the keyboard or terminals UP, DOWN
remains valid.
Frequency command
F0.10
UP / DOWN reference
when running
This parameter is valid only when the frequency source is the digital set value.
when determining the keyboard ▲ ▼ keys or terminal UP/DOWN action, the method
to correct the set frequency that is, the target frequency decreases or increases on the basis of
the operating frequency or the set frequency.
The obvious difference between two settings appears when the inverter is in the process
of ac/deceleration, that is, if the inverter operating frequency is not same as the set frequency,
the different choices of the parameters has very different effect.
