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

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