• Function Key - This key is used to navigate
through the lists of parameters and functions
for setting and monitoring parameter values.
• Up/Down ( , ) Keys - Use these keys
alternately to move up or down the lists of
parameter and functions shown in the display,
and increment/decrement values.
• Store ( ) Key - When the unit is in
Program Mode and the operator has edited a
parameter value, press the Store key to write
the new value to the EEPROM.
Keys, Modes, and Parameters
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, which are primarily 3-character codes. The various functions are
separated into related groups identifiable by the left-most character, as the table shows.
For example, function “A04” is the base frequency setting for the motor, typically 50 Hz
or 60 Hz. To edit the parameter, the inverter must be in Program Mode (PGM LED will
be On). You use the front panel keys to first select the function code “A 04.” After
displaying the value for “A 04,” use the Up/Down ( or ) keys to edit the value.
NOTE: The inverter 7-segment display shows lower case “b” and “d”, which means 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 param-
eters. Error codes use the “E” group, and appear
automatically when a fault event occurs. Refer to
page 6–5 for error code details.
