Note: the pulse reference can only be set via DI4.
3: Panel potentiometer setting
The frequency can be set by adjusting the potentiometer on the panel. The rightmost position of the
potentiometer represents 10V and the leftmost position represents 0V. The relation between the
regulation voltage and the reference frequency is similar to that between the AI and the voltage
signal.
4: AI setting
The setup frequency is determined by the analog input terminal AI.0V ~ 24V/0V ~ 10V or 0mA ~
20mA can be selected for AI. Make the selection via J1 jumper. For details, please refer to the
electrical wiring diagram in Section 3.2
Note: The input (0V ~ 24V/0V ~ 10V/0mA ~ 20mA) will be converted by hardware circuit into 0V ~
10V voltage signal before it is fed into the equipment. After the analog signal is converted into 0 ~
10V voltage signal, the relation between the analog input and the setup frequency is determined via
the eight function codes (F3-2 ~ F3-09).
5: Multi-speed setting
If this parameter is selected, the inverter will be in Multi-speed running mode. To determine the
relation between the reference signal and the reference frequency, F0-09 ~ F0-12 (input terminals)
and parameter F6-14 ~ F6-17 shall be defined.
6: Communication setting
It means that the frequency is set by the outside control system via communication means.

1 The adjustment range of the auxiliary frequency source
corresponds to the main reference frequency
Setting range
2 The adjustment range of the auxiliary frequency source
corresponds to the maximum output frequency
The auxiliary frequency source can compliment the main frequency when frequency fine
adjustment/fine tuning is needed. The auxiliary frequency source can be AI only and is valid only
when items 0, 1, 2 and 3 are selected in F0-F02. Its range and direction are determined by the
corresponding main reference frequency, maximum output frequency and F3-06 ~ F3-09.
Note: When the auxiliary frequency source is enabled and the main frequency is digital reference,
