Its initial value is the value of F113. The frequency can be adjusted through the key “up” or “down”, or
through the “up”, “down” terminals.
“Memory of digital given” means after inverter stops, the target frequency is the running frequency before
stop. If the user would like to save target frequency in memory when the power is disconnected, please set
F220=1, i.e. frequency memory after power-down is valid.
1: External analog AI1; 2: External analog AI2
The frequency is set by analog input terminal AI1 and AI2. The analog signal may be current signal (0-20mA
or 4-20mA) or voltage signal (0-5V or 0-10V), which can be chosen by switch code. Please adjust the switch
code according to practical situations, refer to fig 4-4 and table 4-2.
When inverters leave the factory, the analog signal of AI1 channel is DC voltage signal, the range of voltage
is 0-10V, and the analog signal of AI2 channel is DC current signal, the range of current is 0-20 mA. If
4-20mA current signal is needed, please set lower limit of analog input F406=2, which input resistor is
500OHM. If some errors exist, please make some adjustments.
3: Pulse input given
When frequency is given by pulse input, the pulse is only input by OP1 terminal. The max pulse frequency is
50K. The related function code are F440~F446.
4: Stage speed control
Multi-stage speed control is selected by setting stage speed terminals F316-F322 and function codes of
multi-stage speed section. The frequency is set by multi-stage terminal or automatic cycling frequency.
5: No memory of digital given
Its initial value is the value of F113. The frequency can be adjusted through the key “up” or “down”, or
through the “up”, “down” terminals.
“No memory of digital given” means that the target frequency will restore to the value of F113 after stop no
matter the state of F220.
6: Keypad Potentiometer AI3
The frequency is set by the potentiometer on the control panel.
9: PID adjusting
When PID adjusting is selected, the running frequency of inverter is the value of frequency adjusted by PID.
Please refer to instructions of PID parameters for PID given resource, PID given numbers, feedback source,
and so on.
10: MODBUS
The main frequency is given by MODBUS communication.

· When accessorial frequency Y is given to channel as independent frequency, it has the same function with main
frequency source X.
· When F204=0, the initial value of accessorial frequency is set by F155. When accessorial frequency controls speed
independently, polarity setting F156 is not valid.
· When F207=1 or 3, and F204=0, the initial value of accessorial frequency is set by F155, the polarity of accessorial
