Using Keypad Devices

Inverter Front Panel Keypad
The SJ100 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.

• 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 F_04, Keypad Run Key Routing, determines whether the Run key gener-
ates 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.
• Function Key - This key is used to navigate through the lists of parameters and
functions for setting and monitoring parameter values.
• Up/Down (
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
STR
value, press the Store key to write the new value to the EEPROM.
