Appendix
CHV series inverter function parameters, which are grouped by functions, have P0-PF total 16
groups among which the PF is the expanded function parameters that user can visit if the inverter has
been installed with extension card. Each function group includes a number of function codes, which
adopts three-stage menu, for instance, “P8.08”means the 8
th
function code of P8
th
function.
For the convenience of setting function code by using operation panel, the function group
number is corresponding to Stage 1 menu, the function code is corresponding to Stage 2
menu and the function code parameter is corresponding to Stage 3 menu.
1. The column of function table is described as follows:
The 1
st
column “Function Code” is the function parameter group and parameter code.
The 2
nd
column “Name” is the complete name of the function parameter.
The 4
th
column “Setting Range” is the effective setting value range of the function parameter,
shown on the operation panel LCD (liquid crystal display).
The 5
th
“Default” is the original factory setting value of this function parameter.
The 6
th
“Modification” is the modification performance of the function parameter (i.e. whether
or not it is permitted to modify and the modification conditions), explained as follows,
“
”: indicates that the setting value of this parameter can be modified when the inverter is
either in stop or operating status;
“
”: means that the setting value of this parameter cannot be modified when the inverter is in
operating status;
(Inverter has done the automatic detection restriction to the modification performance of each
parameter, helping user to prevent mis-modification.)
The 7
th
column “LCD Display” is the brief description of function parameter name on the
operation panel LCD (liquid crystal display);
The 8
th
column “Serial No.” is the serial number of this function code in the whole function
codes, and also is the communication register address.
2. “Parameter Digital System” is the decimal system. If parameters are expressed in
hexadecimal system, the value at each digit is independent when the parameter is edited, and
the numeric area of some digits can be hexadecimal (0-F).
3. “LCD Display Description” is only valid when using external LCD operation panel.
4. “Default” indicates the value of the function code after it is refreshed while doing the
manipulation of restoring the factory parameters; but the actually detected parameters or
record values cannot be refreshed.
5. In order to effectively protect the parameters, the inverter provides the cryptoguard for the
function code. After the user’s password is set up (i.e. user’s password P7.00 parameter is not
0), when the user press PRG/ESC button to enter function code edit status, the system first
