9-11
AC10 Inverter
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
8-2.
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.

: 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.
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.

value: 0
When secondary 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 secondary frequency is set by F155. When secondary frequency
controls speed independently, polarity setting F156 is not valid.
When F207=1 or 3, and F204=0, the initial value of secondary frequency is set by F155, the polarity of
frequency is set by F156, the initial value of secondary frequency and the polarity of secondary
frequency can be checked by F157 and F158.
When the secondary frequency is set by analog input (AI1, AI2), the setting range for the frequency is
set by F205 and F206.
When the secondary frequency is given by keypad potentiometer, the main frequency can only select
stage speed control and modbus control (F203=4, 10)
Note: secondary frequency source Y and main frequency source X cannot use the same frequency
given channel.
