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 primarily 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 60 Hz. 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 (
or ) keys to edit it.
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.
