1.3Name and function of each part

1.3.1Operation keypad panel

1	Monitor key

Switches among operation, setting and status monitor modes.

PRG lamp

Lights when the inverter is in parameter setting mode.

Up/down key

Enter key

Reads and writes frequency and parameter data.

Input main circuit terminal block

Used to connect a power source.

RUN lamp

Blinks while the inverter is in operation.

RUN key

Pressing this key while the RUN key lamp is lighted starts operations.

STOP key

Every pressing of this key while the RUN key lamp is lit will cause a slowdown stop.

Frequency adjusting knob (potentiometer)

Allows you to adjust the operation frequency when the inverter is placed in a mode in which the potentiometer can be used to enter operation commands.
