MONITORING CONTROL SIGNALS
AND
OUTPUT
When monitoring functions other than faults, perform
the following procedures. (See Figures 5-2 and 5-3.)
OPERATION PROCEDURE
Function Codes 00 through OA provide “Read
access to inverter control signals and output informa-
tion. These can be very useful in troubleshooting
problems quickly.
Function Codes 06 and 07 will be covered first be-
cause they take an additional step, due to the Func-
tion Code extension, to get to the signal status infor-
mation,
1. Press
RESET
key and confirm that the Function
Selection LED under the second digit of the Func-
tion
Code
Display is lit and that
of it is
2. Press the SHIFT key once to move the Function
Selection LED to the first digit of the Function
Code 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.
3. Press the UP ARROW or DOWN ARROW key to
set the first digit of the Function Code to
4. Press the SHIFT key once to turn off the Function
Selection LED and permit data retrieval.
-- The 4th digit of the Data Display will indicate the
Function Code Extension
(A, b, C, d,
or
E)
of
Function Code “06”.
-- Function Code
be displayed in
and 1 st digits of the Data Display and data
units are shown by the Unit Indicator.
-- Display symbols are “Signal Received = [0],
No Signal Received =
5.
Press the UP
ARROW
key
to
display (in order) the
contents of
b,
C, d, and
E
(of Function Code 06).
6.
Press the
SHIFT
key
light the Function Se-
lection LED under the second digit of the Function
Code Display.
7.
Press the
SHIFT
key a second time to move the
Function Selection LED to the first digit of the
Function Code Display.
-- The Function Selection LED under
digit
will now be lit and the value of this first digit will
be changed in the next step.

All other signals from Function Codes 00 through OA
are obtained using the
same
procedure as Function
Codes 06 and 07, except that the Function Code
extension does not exist.
NOTE: After any operations with the Keypad Panel
have been completed, it is recommended to return
display to Function Code
(Output Frequency)
unless your particular application deems otherwise.
