same time.
18：PLC investment
When the programmable PLC operation selection condition [F5.00] is valid, the
external terminal defined by this parameter can realize the input and removal of
PLC operation.
19：Swing frequency operation input
When the condition of selecting the swing frequency function is valid
([F4.14]=XXX2). The external terminal defined by this parameter can realize the
input and removal of swing frequency operation.
20：UP
21：DW
The inverter can set the operating frequency through the external terminal and
realize the remote frequency setting operation. When the terminal is valid, the set
frequency increases or decreases according to the set rate; when the terminal is
invalid, the set frequency remains. When both terminals are valid at the same time,
the set frequency is maintained. The frequency increases when UP is valid, and
decreases when DW is valid.
[F3.09], [F3.10] define the AI range of the analog input channel, which should be
set according to the actual situation of the connected signal.
The external analog input is filtered to effectively eliminate the interference
signal. When the setting is too large, the anti-interference ability is strong but the
response speed to the set signal will be delayed.
The corresponding relationship between the analog input AI and set frequency
is shown in the figure 6-10.
