6.1 Schedule of Function Parameters 6.1 Schedule of Function Parameters
F0.01 Frequency setting mode selection Setting range: 0~8 Factory default setting: 1
This function is used to select the operation frequency setting mode of the inverter.
0: Operator panel potentiometer setting:
To regulate the operation frequency by operating the potentiometer on the keyboard.
1: Digital setting,1, operator panel
/ key or digital encoder setting
To set the operation frequency by F0.03. The operation frequency can be altered by
pressing the keyboard button or by digital encoder. The modified frequency value will
be stored into F0.03 after power down. If the frequency is not expected to be
saved, just set the parameter F0.02 directly.
2: Digital setting 2, external terminal UP/DOWN setting:
To alter the operation frequency through ON/OFF of external control terminal
defined with UP/DOWN frequency function. When UP-COM closes, frequency rises;
when DOWN-COM opens, frequency falls; when UP/DOWN closes or opens with
COM simultaneously, frequency remains and will not be changed. The modified
frequency value will be stored into F0.03 after power down.
The velocity ratio of operation frequency to be modified by UP/DOWN terminal can
be set by parameter FA.05.
3: Digital setting 3, 485 COM setting:
To set the operation frequency by frequency command of RS485 communication
interface received from the upper (host) machine.
4: External analog voltage signal AVI (0~10V) or external potentiometer setting:
To set the operation frequency by external voltage input terminal AVI. Refer to
F5.00~F5.01 for relevant settings.
: External analog current signal ACI (0~20mA) setting:
To set the operation frequency by external voltage input terminal AVI. Refer to
F5.02~F5.03 for relevant settings.
6: External terminal impulse (0~10KHz) setting:
To set the operation frequency by X6 terminal input impulse signal. Refer to
F5.04~F5.05 for relevant settings.
7: Combined setting:
The operation frequency is set by linear combination of each setting path. The
combination mode is decided by F5.15~F5.16.
8: External terminal selection
To confirm the frequency input path by 8 kinds switching assemblies of external multi-
function terminals. The function terminal is defined by F4.00~F4.05. The path
corresponding to the combination is shown in the table below.

If the operating keyboard provides a digital encoder, it can
substitute the function of / and ENTER keys to realize
regulation of digital frequency, modification of parameters and
store of data. Therefore, when using the function of this digital
encoder, F0.01 shall be set to 1 instead of 0. Otherwise, the
frequency setting by digital encoder will be invalid. If the user
needs an analog potentiometer to realize frequency setting, do use
an analog potentiometer keyboard or an external potentiometer.
If the frequency setting mode is selected to 6, be sure to select
port X6. Others ports are invalid.
If the frequency setting mode is selected to 8, it is applicable to
the occasion of frequency path real-time shifting. E.g., if there is a
need to realize shifting of voltage setting to current setting, it can
be realized by shifting two combinations: the multi-function
terminal "100" and "101". Also, this can be realized by the multi-
function terminal defined with "frequency shifting to ACI"
directly.
