•Parameter Display - A 4-digit, 7-segment display for parameters and function codes.

•Display Units, Hertz/Amperes - One of these LEDs will be ON to indicate the units associated with the parameter display.

•Power LED - This LED is ON when the power input to the inverter is ON.

•Function Key - This key is used to navigate through the lists of parameters and functions for setting and monitoring parameter values.

• Up/Down ( 1 , 2 ) 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 ( STR ) Key - When the unit is in Program Mode and you have 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 that 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 “A_04” 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 ( 1 or 2 ) 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
