SETTING FUNCTION CODES
To change Function Codes settings, perform the fol-
lowing procedures. (See Figure 5-2)
NOTE: For convenience, always change the second
digit of a Function Code first since changing the
second digit always returns the digit to a value of
zero.
NOTE: the inverter is running and a Function Code
is changed that is not permitted to be changed while
running, an
fault be displayed. Press RE-
SET key to clear this fault and continue.
NOTE: Function Code data is “protected’ (Function
Code
it cannot be changed until Function Code
99 is changed to See ‘Data Protection’
paragraph in this section.
OPERATION PROCEDURE
1. Press RESET key and confirm that the Function
Selection LED under the second digit of the Func-
tion Display is lit and that the value of it is
2. Press the UP ARROW or DOWN ARROW key to
set the second digit of the Function Display to the
second digit of the Function Code to be changed.
3. Press the SHIFT key once to move the Function
Selection LED to the first digit of the Function
Display.
-- The Function Selection LED under the first digit
will now be lit and the value of this first digit will
be changed in the next step.
4. Press the UP ARROW or DOWN ARROW key to
set the first digit of the Function Display to the first
digit of the Function Code to be changed.
5. Press the SHIFT key once to turn off the Function
Selection LED and permit Function Code data
changes.
6. Press the UP ARROW or DOWN ARROW key to
change data of the Function Code selected to the
desired new value.
To make large changes, use FAST key to-
gether with UP or DOWN ARROW keys. Press
UP or DOWN ARROW key first (data will change
in tenths of units), then press FAST key once to
change data in single units, or press FAST key
twice to change data in tens of units.
-- Data Display data will blink durning change
procedure and when desired value is reached.
7. Press the SET key to set the new Function Code
value into memory.
-- Data Display will cease to blink after the data
has been set into memory.
8. If additional Function Codes changes are desired,
press SHIFT key and repeat steps 2 thru 7 of this
procedure.
NOTE: After any operations with the Keypad Panel
have been completed, it is recommended to return
the display to Function Code
(Output Frequency)
unless your particular application deems otherwise.
FUNCTION OF RESET KEY AFTER
CHANGING FUNCTION CODE DATA
Pressing RESET after finishing Function Code changes
will always return the display to one of the Operation
Monitoring Function Codes (Function Codes that
begin with zero). The particular one that it is returned
to can be changed by selecting the desired Function
Code and leaving it there for approximately two or
three minutes without pressing any of the keys on the
keypad.
NOTE: The “Power-Up will be the same
Function Code as the ‘Return Via Function
Code.
FAULT INDICATION AND RETRIEVAL
When a fault occurs, the mode is automatically switched
to the Fault Monitoring mode. The fault Function
Code will be displayed in the Function Display, the
number (in order) and type of fault will be shown in the
Data Display (blinking), and the Function Selection
LED for the first digit of the Function Code will be lit.
The fault indication function is composed of the fol-
lowing three parts:
Indication of present fault.
2. Indication of operating conditions at the time that
the fault took place.
3. Indication of previous faults.
If the fault is a multiple fault, indication can be re-
trieved in the order of (up to seven faults)
by Function Code FO,
In addition, the operating conditions at the time of the
first fault can be indicated by Function Codes
through
F4 (only for present fault; after RESET, this
information is lost).
Also, the first fault for the past three fault trips can be
indicated by F5 through F7.
NOTE: First fault means the first detected fault when
mu/tip/e faults occur at the same time.
