The following wiring diagram shows the power and motor connec­tions for basic operation. The optional signal input wiring supports
external Fwd and Rev Run command, and a speed potentiometer.

Stop/Reset Key

• Run/Stop LED – ON when the inverter output is ON and the

motor is developing torque, and OFF when the inverter output is
OFF (Stop Mode).

• Program/Monitor LED – 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 – 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 which 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 parame-

ters 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 – 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 to
increment/decrement values.

• Store Key – When the unit is in Program Mode and the operator

has edited a parameter value, press the Store key to write the new
value to the EEPROM.
