Key and Indicator Legend

•Run/Stop LED - On when the inverter output is running the motor (Run Mode), and Off when the inverter output is Off (Stop Mode).

•Program/Monitor LED - This LED is On when the inverter is ready for parameter editing (Program Mode). It is Off when the parameter display is monitoring data (Monitor Mode).

•Run Key - Press this key to run the motor (the Run Enable LED must be On first).

•Run Enable LED - is On when the inverter is ready to respond to the Run command, Off when the Run command is disabled.

•Stop/Reset Key - Press this key to stop the motor when it is running (uses the programmed deceleration rate). This key will also reset an alarm which has tripped.

•Potentiometer - allows an operator to enter data for selecting a scalar value from a range, associated with the inverter output frequency.

•Potentiometer Enable LED - On when the potentiometer is enabled for value entry.

•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 to alternately 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 the operator has edited a parameter value, press the Store key to write the new value to the EEPROM.
