According to the preceding figure, the running frequency of the AC drive can be set by
means of function codes, manual adjustment, analog input, multi-speed terminal, external
feedback signal, internal PID regulator, or the host computer.
Set the corresponding function codes of each frequency setting mode, as shown in the
preceding gure.
4.8.2 Frequency Setting by the Auxiliary Frequency Source
The frequency setting by the auxiliary frequency source is the same as the frequency setting
by the main frequency source. You can set the auxiliary frequency source in F0-04.

The relationship between the target running frequency and the main frequency source and
auxiliary frequency source is set in F0-07, as follows:
1) Main frequency source X: The main frequency source is directly used to set the target
running frequency.
2) Auxiliary frequency source Y: The auxiliary frequency source is directly used to set the
target running frequency.
3) X and Y operation: There are four operation methods, namely, X+Y, X-Y, maximum of X
and Y, and minimum of X and Y.
4) Frequency switchover: A DI terminal is used to switch over between the preceding
three frequency setting channels.
