The L100 Series inverter front keypad contains all the elements for both monitoring and
programming parameters. The keypad layout is pictured below. All other programming
devices for the inverter have a similar key arrangement and function. The DOP Plus PC
software has an on-screen keypad as well.
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 ( , ) 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 ( ) 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.
