3-2 Using the Keypad Devices
The MX2 Series inverter front keypad contains all the elements for both moni-
toring and programming parameters. The keypad layout is pictured below. All
other programming devices for the inverter have a similar key arrangement
and function.
3-2-1 Key and Indicator Legend
• Run LED - ON when the inverter output is ON and the motor is develop-
ing torque (Run Mode), and OFF when the inverter output is OFF (Stop
Mode).
• Program LED - This LED is ON when the inverter is ready for parameter
editing (Program Mode). It is OFF when the parameter display is monitor-
ing data (Monitor Mode).
• Run Key Enable LED - This 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.
• 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 indi-
cate the units associated with the parameter display.
• Power LED - This is ON when the power input to the inverter is ON.
• Alarm LED - ON when an inverter trip is active (alarm relay contact will
be closed).
• Cycle Key - This key is used to escape from the current situation.
• Up/Down keys - Use these keys alternatively to move up or down the lists
of parameter and functions shown in the display, and increment/decre-
ment values.
• Set key - This key is used to navigate through the lists of parameters and
functions for setting and monitoring parameter values. When the unit is in
Program Mode and you have edited a parameter value, press the Set key
to write the new value to the EEPROM.
