Using the Keypad Devices
The WJ200 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.
Key and Indicator Legend
 Run 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 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 – 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

, 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 indicate 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).
 Escape 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/decrement 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.
