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.
