Using the Front Panel Keypad
Please take a moment to familiarize yourself with the keypad layout shown in the figure
below. The display is used in programming the inverter’s parameters, as well as monitor-
ing specific parameter values during operation.
Key and Indicator Legend
• Run/Stop LED - ON when the inverter output is ON and the motor is developing
torque (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 Enable LED - is ON when the inverter is ready to respond to the Run key,
OFF when the Run key is disabled.
• Run Key - Press this key to run the motor (the Run Enable LED must be ON first).
Parameter F004, Keypad Run Key Routing, determines whether the Run key generates
a Run FWD or Run REV command.
• 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 that has tripped.
• Potentiometer - Allows an operator to directly set the motor speed when the potenti-
ometer is enabled for output frequency control.
• 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.
• Alarm LED - ON when an inverter trip is active (alarm relay contacts will be closed).
• 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 alternately to 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 you have edited a parameter
value, press the Store key to write the new value to the EEPROM.
