Inverter Front Panel Keypad

The CR100 Series inverter front keypad contains all the elements for both monitoring and

programming parameters. The keypad layout is pictured below. The fan VFD is programmed in

the factory before shipment and no field programming is required.

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 F_04,

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 potentiometer 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 (

) 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.
