Operation and Simple Running 8-8
AC10 Inverter
8.3.4 Setting the frequency with analog terminal and controlling the
operation with control terminals
i. Connect the wires in accordance with
Figure 8-3. After having checked the wiring
successfully, switch on the mains supply, and power on the inverter. Note: 2K～5K
potentiometer may be used for setting external analog signals. For the cases with
higher requirements for precision, a precise multiturn potentiometer is
recommended, and adopt shielded wire for the wire connection, with near end of
the shielding layer grounded reliably.

ii. Press the “M” key, to enter the programming menu.
iii. Study the parameters of the motor: the operation process is the same as that of
example 1. (Refer to 8.3.1 for tuning of the motor).
iv. Set functional parameters of the inverter:
Function code Values
F203 1
F208 1
v. (5) There is a red two-digit coding switch SW1 near the control terminal block, as
shown in Figure 4-4. The function of coding switch is to select the voltage signal
(0～5V/0～10V) or current signal of analog input terminal AI2, current channel is
default. In actual application, select the analog input channel through F203. Turn
switches 1 to ON and 2 to ON as illustrated in the figure, and select 0～20mA
current speed control. Other switches state and mode of control speed are shown
in table
Table 8-2.
