The User Manual of 580 Series General Frequency Converter

4.2 Checking and modification of function code

Three-level menu structure is used by the operation panel of 580 frequency converter for parameter setting and other operations.

Three-level menus comprise: Function parameter set (Level I menu) →Function code (Level II menu) → Set value of function code (Level III menu). The operation flow chart is as shown in Fig. 4-2.

Fig. 4-2 The operation flow chart of three-level menus

Note: Level III menu can be returned to Level II menu by means of PRG key or ENTER key. The difference between two keys is as follows: Press ENTER key to save the set parameter, return to Level II menu and transfer to the next function code; press PRG key to cancel current parameter modification and directly return to Level II menu of current function code.

For example: Function code F3-02 is changed from 10.00Hz to 15.00Hz.

In Level III menu, if the parameter does not have flicker bit, this situation indicates that the function code can not be modified, for which the possible reasons are as follows:

1) This function code is an unchangeable parameter, e.g. frequency converter type, actual detecting parameter, running record parameter, etc.

2) This function code can not be modified in the running state, but shall be modified after the equipment is stopped.

4.3 Organization mode of function code of frequency converter

Table 4-2 The organization mode of function code of frequency converter

Function code block	Function description	Description
F0～FP	Function code of general-purpose frequency converter
A0～AC	Enhanced function code block	Multi-motor parameters, AI/AO characteristic calibration and optimal control
U0～U3	Running state parameter set	The display and reference of basic characteristic parameter of frequency converter

In the browse of function code, select the function code block No. expected for reference by means of Key or Key , as shown in the following figure:

Fig. 4-3 The browse of function code block No.

Therein, Function Code FP-02 is used to control the display of Function Code Block A, U.

FP-02	Default value: 11
	Set value	Tens place	Ones place
	Function	A group display selection	U group display selection
	Set range	0: Not displayed; 1: Displayed	0: Not displayed; 1: Displayed
