17.4 Keypad Navigation
When attempting to control and set various parameters for the inverter it would be useful for the user to become
familiar with keypad navigation and to go through a few function changes before making the final settings.
17.4.1 Basic Keypad Control
(
Factory Default
,
b000=0000 & b004=0000
)
In its basic form as received from the factory, the inverter output is controlled from the keypad. Please refer to the
A
and
b
parameter list (Sec. 19.0) to view the factory default settings for the various parameters. When the inverter is
powered up, the display will be flashing and momentarily show the inverter
input voltage
. The flashing display will
then switch to a minimum output frequency of
05.00Hz,
the
FWD
LED will be flashing and the
Hz/RPM
LED will be
on
.
By pressing the
STOP / RUN
key the output is active (
RUN
) and the display is on solid as is the
FWD
LED. Using the
<
/
RESET
key to select the digit
position
and the
UP/DOWN
keys to select the digit
value
, the output frequency
may then be set from
00.0 to 50.0/60.0Hz
with minimum increments of
00.1Hz
. The
FWD/REV
key may be toggled to
set the output direction. Both the output frequency and the output direction can be set when the inverter is in the
RUN
or
STOP
mode. When the
RUN/STOP
key is toggled to
STOP
, the set frequency is displayed and the display is again
flashing. The
<
/
RESET
key also functions to initiate a
RESET
after a Fault is cleared
.
