Using the Front Panel Keypad

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

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.
