Keys, Modes, and Parameters
The purpose of the keypad is to provide a way to
change modes and parameters. The term
function
applies to both monitoring modes and parameters.
These are all accessible through
function codes
that
are primary 4-character codes. The various functions
are separated into related groups identifiable by the
left-most character, as the table shows.

For example, function “A004” is the
base frequency setting
for the motor, typically 50Hz
or 60Hz. To edit the parameter, the inverter must be in Program Mode (PRG LED will
be ON). You use the front panel keys to first select the function code “A004”. After
displaying the value for “A004”, use the Up/Down keys ( or ) to edit it.
N
OTE: The inverter 7-segment display shows lower case “b” and “d”, meaning the same
as the upper case letters “B” and “D” used in this manual (for uniformity “A” to “F”).
The inverter automatically switches into Monitor
Mode when you access “D” Group functions. It
switches into Program Mode when you access any
other group, because they all have editable
parameters. Error codes use the “E” Group, and
appear automatically when a fault event occurs.
“P” group appears when DeviceNet communication
is available. Refer to “Monitoring Trip Events,
History, & Conditions” on page 6-5 for error code
details.
T
IP: Pressing FUNC key continuously for 3 seconds makes the display back to d001.
