4.2 Checking and modification of function code
Three-level menu structure is used by the operation panel of JAC200 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.
