• Store ( ) Key – When the unit is in
STR
Program Mode and the operator has edited a
parameter value, press the Store key to write
the new value to the EEPROM. This param-
eter is then displayed at powerup by default.
If you want to change the powerup default,
navigate to a new parameter value and press
the Store key.
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 primarily 3 or 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 50 Hz or

You use the front panel keys to first select the function code "A004." After displaying the value
for "A004," use the Up/Down (
NOTE: 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.
Refer to "Monitoring Trip Events, History, &
Conditions" on page 6–5 for error code details.
