Run Key
The display is used in programming the inverter's parameters, as well as monitoring specific
parameter values during operation. Many functions are applicable only during the initial instal-
lation, while others are more useful for maintenance or monitoring.
Parameter Editing
The front panel controls and indicators are described as follows:
and Controls
• Run/Stop LED – ON when the inverter output is ON and the motor is developing torque,
• Program/Monitor LED – This LED is ON when the inverter is ready for parameter editing
• Run Key Enable LED – is ON when the inverter is ready to respond to the Run key, OFF
• Run Key – Press this key to run the motor (the Run Enable LED must be ON first). Parame-
• Stop/Reset Key – Press this key to stop the motor when it is running (uses the programmed
• Potentiometer – allows an operator to directly set the motor speed when the potentiometer
• 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/Volts/Amperes/kW/% – These LEDs indicate the units associated
• Power LED – This LED is ON when the power input to the inverter is ON.
• Alarm LED – This LED is ON when an alarm condition has tripped the inverter. Clearing

LED is ON. In the case of kW units, both Volts and Amperes LEDs will be ON. An easy
way to remember this is that kW = (V x A)/1000.
