Using the Front Panel Keypad

Front Panel Introduction

Please take a moment to familiarize yourself with the keypad layout shown in the figure below. These are the visible controls and indicators when the front panel door is closed.

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 installation, while others are more useful for maintenance or monitoring.

Parameter Editing Controls

Installation and

Mounting Inverter

 

 

Now, open the front panel (half-door) for second-level access to reveal additional operator keys for parameter editing as shown to the right. In normal operation after installation, parameter editing is unnecessary, so these controls are hidden from view. The front panel controls and indicators are described as follows:

•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).

Keys

•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 potenti- ometer is enabled for output frequency control.

•Potentiometer Enable LED - ON when the potentiometer is enabled for value entry.
